whats chance new apps pluggins
would be nice Amazon or allexa plugins and a yale plugin
You could always create your own plugins - most of the plugins are written by third parties. If you wanted to suggest an official one I'd go through #feature-request
But what would a Amazon or Alexa plugin even do is what I'd wonder.
conect to my alexa and keys for action
Unfortunately, Amazon doesn't have any easy way to let you control Alexa devices from other places, which you'd need to be able to make that sort of Stream Deck plugin. You might be able to do it with HomeBridge and Home Assistant working together, but that's a deep rabbit hole that you might not want to get into.
You can try this workflow. It's primarily setup through your Alexa device and then using the multiaction and website buttons. https://www.reddit.com/r/elgato/comments/1j6w8k1/integrating_alexa_with_stream_deck_a_stepbystep/
Oooh, I had no idea that was a thing
👍

Sorry if this is the wrong place.... Just got a StreamDeck+, anyone know of a plugin or dial action that lets me adjust volume and also toggle through my active applications by pressing the dial? If anyone is using the Discord "User Volume Control" dial, that's what I'm after but for active applications.
maybe the one labled "volume controller" or the "wave link" one ?
are you using wave link 3.0 beta, or wave link 2.0, or just windows directly?
I am having a hard time with Elgato market place talking to my OBS. The market place plug in is downloading right but when I open it in OBS nothing shows up.. please help.
Can you elaborate on "nothing shows up"? is the plugin just loading an empty window?
Keep in mind Marketplace only works with scene packs, not all the assets as well.
It's somewhat common for folks to expect to to have other assets in it as well, but those still require manual use
So if I download a Overlay Pack like the Dark Matter one on Elgato Market Place and it goes into my Library.. I Open up OBS and I go to tools and them Market place Connect it says " you don't own any scene collection products yet.
Hello. I am having the same issue. Is there a way I can show you via Discord's streaming?
Overlays aren't Scene Collections. You need to add in the Overlay as you would any other overlay from the downloads.
Marketplace connect is generally used for importing (or exporting) an entire scene collection to do a complete setup, not individual components
How can I add a full complete setup? I nothing shows up that I’ve downloaded from Elgato
are you using the elagto markeplace connect plugin for OBS?
oh, i just scrolled up to see the rest.
there was an update I got today, and testing this out
What the hell. I can't log into my elgato account on the offical website. or when using my phone or another laptop/pc. when i go character icon and press login. it just got a spinning icon. Anyone else having issues???
Can't even log into market place either
On offical site. Only shows. Submit.
I have cleared cache, dont all basic stuff.
what browser are you using?
Microsoft Edge. But also Tried firefox and chrome
same result?
Never had issue before. only just happened. Yes same result
strange, as I'm on it, are you in the US, our outside of?
Am in UK
idk if the server is having updates etc... outside of the us, but reach out to #official-tech-support and they might be able to assist.
I want to export a single scene upload it to the marketplace, but the file i get is 0byte...
Anyone else eith this kind of issue?
Hi Alva-
I assume you mean the marketplace connect for OBS plugin? If so, unfortunately, it only has the ability to export an entire scene collection (not just a single scene). The ability to export just specific parts of a scene collection is a feature we are looking at.
That said, you should be seeing a file larger than 0 bytes exported. Can you please try exporting again, and when the export is complete, go to Help -> Logs -> Upload Current Log File, then either post the link it gives you here, or DM it to me? That way I can see if there is any logged error going on.
Hey Finite,
i try it with a complete new OBS Portable, just with the one scene and it works. Dont know why the other OBS dont works, but im fine with it.
If you want to have the log file to improve the Plugin, let me know
I would love the log file if you've got a few minutes to generate one, as it would help with the development.
Also, glad you've at least got it working with the new portable install.
Hopefully this is the right place to ask this question, if not just let me know where I should go.
For the native elgato twitch app, the "send message" includes channels you mod for, this is great, however the list of channels available seems to be capped at 20, leaving some names off the list.
I use another plugin to solve this when I'm at my PC, but it's not compatible with my primary use mac device.
I know it's a small thing, just curious if the channel limited could be increased, or maybe have the option to "ignore" a channel to free up space for it to cycle in new options.
Thank you for your time & Merry Christmas!
That'd probably be best sent to the links in #feature-request
Thank you.
Hello and Happy Holidays everyone! This seems like an utterly basic issue:
From the Windows 11 app (on a Stream Deck+), any plugin I try to install fails. Anything. With this message. I was able to install one plugin ("Windows Display Settings") by downloading and double-clicking it, but have not been able to repeat that workflow. What am I doing wrong?
Make sure your Stream Deck app is actually signed into Marketplace, and that you're using the same account that you used to sign into the Website (I've seen it throw this error if someone signed into the app with an Elgato account, but the Website with a Google account, for example).
If it's signed in correctly in both locations I'd suggest signing the app out and in to be safe. If that doesn't do anything, check in %appdata%\Elgato\StreamDeck and see if you have a cache.db file (seeing this requires you have the option to show hidden files enabled). If you do, you can try exiting the app (don't forget to close it form the system tray down by the clock too), then rename the cahce file to something else (don't delete it in case you need to put it back). Then restart the app and try installing plugins again
Thank you - it was signed into different accounts as you suspected. This happened because signing into the top-level elgato.com web site doesn't offer google login, so I set up a new account for that at some point. Anyway, even after sync'ing the logins, I had to quit the app and restart it but now seems like it's all good. Thanks so much!
Glad you've got it sorted out
Hello, Team! I still have this issue even on a freshly-installed copy of Windows 11. Tried checking stuff by pressing F12 and going to Sources to see where the problem might be lying, et voila.
This has also been happening even to the other two computers I have tried downloading SD plugins off of, as early as last month, even after the BarRaider issue, and even with a new copy of Win11 on this third PC, I'm still not getting a good experience with the site.
Please help. I just want to redo my Deck configurations. 🙏🏻
Hey Elgato team, thanks for all you do! I recently bought this stream package: https://marketplace.elgato.com/product/plasma-e7fedd6b-22c1-4883-8261-21adc7ebd2f2. The readme file is no longer accessible. Is there an alternative I can use to help me set this up?
There is no sales allowed on the server between users, do that on ebay or such.
<@&581565551495741448> a few channels for the same request. (I totally understand they want a special edition, but they'd have to wait for Elgato to mention that it's in stock.)
They're coming from another server I also moderate, and I told them to stop doing it 
Thanks Calu!
Hello people, i need help for my new microphone elgato wave 3. For dowload VST on marketplace is very simple but for me no ... I have the 2.0.6 version and this message appear when i try to download VST.
@wispy mason if you can please send me a DM, I'll help look into this with you.
The message is informing but should not be blocking the download. Can you check that Wave Link was open when this window popped up? It should open it in Wave Link.
I have a general questiuon abour Wave Link. I currently use this software, however, when either PC goes into rest mode after 10 minutes, wave link disconnects and I can no longer hear audio. I have to end task and re connect again. Anyone else having this issue?
Dose anyone know what this is for starcitizen i like it allot
probably just a profile on the Marketplace with a background for the touchstrip
could be one of these https://marketplace.elgato.com/search?q=star citizen&extension=profiles
i have that for the deck pluss. might be for the others. but yet that had diles. or it could be a whole new 1
the guy that made those profiles did get the keyboard early so he could of made them and not released yet
Thank you
Crossover products like this are going to split things a bit awkwardly between 2 different Subreddits and Discord servers. 🫠
Elgato and Corsair have created profiles and worked with makers to create profiles ahead of launch for popular games. These will be available on Elgato Marketplace for launch.
App plugins, key icons, profiles, and more available on Elgato Marketplace
Regular stream deck users are a lot more familiar with profiles than I am, but I thought it was possible to share files directly - outside of the Marketplace.
You can do it without market place but usually it’s more safer if you get them from the marketplace
Thanks for confirming.
Just wanted to make sure it was possible. I'm confident that Phil can be trusted. 😊
Good morning, I would like to know if the XLR hub for Stream Deck Plus is still manufactured, because I can't find it to buy here in Brazil.
yes, it's an awesome combo.
idk about in Brazil though.
Hi Dino, this channel is more for the digital products than our Elgato store front. That said, I believe Brazil is more limited on product sales due to the way our company distributes. If you create a ticket with Elgato Support they'll be better able to assist you with any purchase availability questions.
Thanks Vic
Thanks Klov3r
my cat found my keyboard, sorry for the spam everyone! 

sure blame it on the cat we all know the truth
XLR dock for stream deck + is sold out quite a while… is there any prediction to get on stock?
No we don't know when this will be, they can't provide predictions. They will sometimes announce restocks in #announcements so be on the lookout!
Just a heads up, this channel is for the Elgato Marketplace webpage/app for the Stream Deck.
hello i joined this server cuz i was frustrated with the Elgato Marketplace
i have tried several times but my card keeps getting declined
i double-checked the details and its all correct
what im trying to do was to buy Elgato Voice Focus,i already earned enough to buy it but couldnt
please help?
Is it possible your bank may be rejecting the charge thinking its fraud? Mine does that sometimes.
Anything with payment has to go through customer support - you can go through the link in#official-tech-support to get the email form or phone numbers. This is community support, we don't have access to see why your order isn't processing.
Only other thing we could suggest is trying a different payment method if you have one available, or otherwise following up with your financial institution to see if they can see if the charge is failing (or if they're blocking it for some reason)
I downloaded and installed discord plugin on my new Stream deck + but the plugin doesn't seem to work. I've already deleted the plugin and reinstalled it or even deleted streamdeck and reinstalled streamdeck on my pc again but then adding back the discord plugin it's still not working. I don't get a msg on discord saying that I need to authorize streamdeck or something so I also can't deauthorize it on discord (which is what someone recommended me on reddit).
I have the plugin in the streamdeck app and when I drag a discord function like "go to text channel" to a button then I'd guess that I'd have to select a server and channel but it says "No Server" and "No Channel" and that's it.
hey guys,
Every time i try to purchase something, it comes up with 0 dollars for price and i cant buy it. i have bought before on the store and could download it with no porblem. also i can still add free items, its only the ones with price.
If your buying from icon city you should try there site instead. Could be anything like profile not connecting right or problem with elgato. You could try the #official-tech-support
yeah i bought it on their website in the end. thanks!
I cryptolevel - we are tracking the sales issue that happened over the weekend. If you still see that issue happening on Marketplace please let us know.
best to ask in #stream-deck
ig this is a plugin q sooooooo: i have the official elgato weather plugin and i would like it to be in fahrenheit instead of Celsius, can someone help me with this?
In the settings for the plugin, once you've assigned it to the button.
How we've survived as a species is beyond me. 😐
is there anyone who knows when you can make a application for spotify cause I want to use the plugin for spotify by BarRaider', but I am unable to connect since spotify disabled it.
Only Spotify would know since they're the ones who turned off the APIs
Not for direct control. You cna use the Windows media controls, but they switch to the last used app, so if you wind up opening say Youtube after loading Spotify you have to tell windows to swtich back what you want to control
thank you!! for the information, waiting it is
Have you checked out the latest update to Elgato's Spotify plugin? 🤔
yea but I want to use the playlist shortcut, from the BarRaider plugin, hopfully they give us some news soon
How can i put on my stream deck to change tehj sides of stereo
hey my elgato just says no device connected im trying to stream a switch 2 game? nothing is working
i hope this is the right channel...
It is not, but it looks like you found the right one. This one is for things on the Elgato Marketplace, like unable to purchase plugins and such.
Ah thanks
hello stupid question, but I am unable to find the new updated spotify plugin, is there anyone who has the a link to the plugin
is that the plugin where there was a update for
Yes - see the version history. They also added support for Windows, this one was previously macOS only.
Owh awesome, thank you!!
Heyo! Just got my Galleon 100 SD, and I'm trying to find apps for my dial screen.
I basically want the Now Playing button, but with a progress bar, and that works on my dial screen instead of a button.
prolly be awhile tell that happens or reach out to the person that makes the plugin in u want to use
<@&581565551495741448>
just in the progress for building plugins for Galleon 100 SD slide into my dm's for a chat
When come the ApelMusic Plugin for Windows ?
Is there any plans to be able to pay on the marktplace other then with credit card? i really wanted to get profiles for my Galleon 100 SD but i dont own a credit card
I think they mentioned they were looking into it on a stream a while back, but nothing confirmed or anything. So no solid answer on when or even IF it will happen at this point. I'd suggest lobbing a suggestion in through #feature-request
If you have a debit card, it should work.
Hello , haven't seen anything about it myself. But is it possible to buy a redeem code for Stream Deck Mobile PRO , i would like to gift it to my friend. And i saw on the app when you try and buy it, next to it says , "REDEEM CODE"
Is there tax added onto the wave cast purchase or something? it was £36.77 GBP on the store but just checked and £44 came out
If there's a sales tax in your region, generally yes. It should be showing up in checkout though, after it calculates the subtotal (but not in the cart).
What's the hold up with restocking Green Screen XL? Still shows as sold out.
Hey, i made a plugin (its on draft still and didnt send it) i change my mind and want to make it free. How i delete a draft plugin? i cant find the option
That's a better question for the makers discord that you can find up the pinned posts. That's the place for questions about making plugins and dealing with publishing them
oh i just clicked the link on the Footer. Thanks @round silo
No problem, good luck with it
How can i delete a draft from the maker console, its preventing me from fixing what im working on.
nvm over on the makers disc now
Hey @jaunty violet what payment method are you thinking about?
PayPal would be the best option, since its basicly used everywhere
I mean i was able to buy my keyboard with paypal so i should be able to buy the add on for the streamdeck with it as well
Hi from a perspective of a maker, I would like to know if there's a way for the importer's side to import the scenes in the exported scene collection to their current scene collection instead of creating a new scene collection when merging with the current. Because makers like me are just making scenes for the users instead of a whole scene collection. And it looks like some crashes sometimes happen when merging scene collections, which I think would decrease the confidence of a user about their stuff being intact after creating a new scene collection.
For questions related to Makers check the Maker's Discord in the pinned messages
Anyone know anything about order pending after payment taken?
Money left my account immediately but order’s still stuck on pending so can’t download. Was hoping to use now as there’s normally no wait to download
For something like that check with support - there's a phone number link in #official-tech-support and they can look into it. You can also open the help link and tell the chat system to open a ticket if you'd rather not call in.
When there is a processing delay though it usually doesn't take too long
But doesn't hurt to check in to be sure
Ah good to know, thanks! Will check with them
Dang the wave xlr pro is what I have been looking for in a mixer!
Can't wait to try it. Wish it would come sooner
Hi,
Who is experiencing issues with the Discord integration after the latest update?
Team is looking into it
For now you can backup your profiles and roll back to 7.2.1 if you need to
Okay, that's what I wanted to know about the new Wave Link software: do I need to uninstall the old one first and then install the new one?
You'll have to uninstall first

👍
Home assistant plugin broke for me as well, can it be a similar issue?
gives a fix?
It should work in 7.2.1, yes. The issue is 7.3.0 specific.
If you mean is a fix out for 7.3 yet, no.
I'm having a problem with the Elgato "Discord" plugin.
The plugin is asking for Discord authorization.
I've clicked "Request Access" several times, but nothing happens.
I've already restarted Discord, restarted StreamDeck, and uninstalled and reinstalled the Discord plugin. I don't know what else to do.
This is a known issue, I actually was just looking to see if the update has happened
same problem, i also reinstalled discord and stream deck but still need discord authorization
fix in 7.2.1
7.3.1
ups 7.3.1 xd
Question for the plugin pros out there: I'm looking to have a pop up or some kind of reminder to take a break after an hour and half of stream time. I was hoping for the reminder to just be on my end, not broadcast or twitchside. I was thinking to just add a huge delay after my start stream button, but that seems impractical. Is there a better way out there that ya'll know of?
ty in advance!
I paid it carelessly and need to apply for a refund.
I don't have the relevant equipment
If on Windows, you could utilize the built-in clock or even if you have a stream deck create a flow that opens the clock app....that way when you press the button it will open all of your programs for streaming plus the clock app and start the timer [manually] when you're ready.
If you'd type that in #stream-deck instead so people can possibly help 🙂
my bad, will do. wasn't sure where to put this tbh. 😅
You can apply for a refund here: https://www.elgato.com/es/es/s/contact

hey all marketplace seem to crash my obs any help
There's a beta update to it at www.elgato.com/s/beta you might want to try that might resolve this
👍 
thats works thanks 🙂
Excellent, glad to hear it's working
Any good plugin that can work as de-hummer?
as in a ground loop eliminator? narrow band EQ on 50/60hz or whatever your power grid operates at.
Heya, I got a question..
So I downloaded the Spotify Plugin by Elgato and in the picture is shown, that I can skip to the next or previous track. That is not included...
I reinstalled it already but it didn't fix it.
(Picture will be attached)
I can only speak for the new Corsair/Elgato keyboard. The plugin works perfectly there.
I only got these four... Like play/pause, random playback, repeat and volume..
Jap xD
dann kann ich auch deutsch schreiben fix
Also bei mir bei dem plug in nur multimedia angezeigt
Hätte nich gedacht, dass ich hier nh Deutschen finde so schnell haha
Interessant...
ah hab deinen fehler
geh mal beim steamdeck program auf dials und nicht tasten
das wechseln geht nur mit den Reglern
ok hab noch nen fix
hast du es auf deinem deck auf ner taste belegt?
wenn ja klick das Feld an und unten bei aktion klickst du drauf und wähl weiter aus
OHA
dann machst du noch nen feld mit der belegung und machst zurück
Heißt ja nd umsont "Wiedergabesteuerung" und nich nur "Start/Stop"
<@&581565551495741448>
Mine always asks for request authorization but it never connects...
I have it and it just doesn't work. Idk why... i have a macbook pro m4pro
I don't know why it's not working either
why not use the elgato one i dont have any problems with it? https://marketplace.elgato.com/product/discord-e3559f36-d31d-4529-ab1f-739955e2ac7a
I've been using that too is really good
This one i have also tried. But it still does the same thing that's stuck authorizing discord and it never works
I have tried resetting everything, all the authorization codes match, everything is setup but it just disconnects every time i press something
<@&581565551495741448> it's in most channels
When we take actions it usually cleans the different channels. But it can take some time before it disappears. 
ah, still in wave channel ^^
Someone didn't clean
brings out the mop


I found a bug with a Market Place Plugin with the "Discord by Elgato" using a Stream Deck+. Not sure where to file this bug report. I chatted with the AI bot on the Elgato website but I want to ensure this bug report goes to the right person. I'm going to dump my findings here. Hopefully it goes to the right person.
Steam Deck version: 7.3.1 (22604)
Discord Plugin version (2.2.0.98)
When using the Discord Plugin version (2.2.0.98) the "User Volume Control for Dials" has a bug where when you "press" in on the { Dial } it should be going to the "Next User" if you have the setting set to "Any User".
Currently when you press in on the Dial its "muting" the user instead of moving to the next user. I can also mutes the user by pressing on the touch screen showing that user which is what it should do.
Ask the chat bot to submit a ticket, and it should let you file a ticket to go to support to report the bug.
Thank you for replying. Do you get some type of support ticket number if you need to keep tabs of the bug report?
so the issue is how do i get the plugins to run on 2.0, cuz it keeps saying it's launching 3.0 and since i dont have it, it does nothing ( i reinstalled windows so i had to reinstall 2.0) and now i cant get my plugins to get in
Assuming you're talking about the Stream Deck plugin, go get the Wave Link (Legacy) plugin. That's the version meant for 2.x
Not sure if this is the right place to ask, but felt like the best place. But I was wondering if anyone knows if Elgato plans to update their Apple Music plugin to work for Windows? I see it only works on MacOS. Trying to get rid of Spotify subscription but the Spotify plugin has the album art and title of song being played. So it’s hard to switch fully. Thanks for any info🙂
That's exactly what I submitted a ticket for. I was only told that the idea would be passed on, but I don't know if anything will happen.
I saw that Phil the technical marketer 9 months ago also uses Apple Music on windows
Yeah but we cant download this skill xd
lol I guess not. Going to continue using Spotify for now then, thanks for responding and submitting a ticket to them, I'll see if I can do the same 🫡
Does anyone know if its possible to set up a dual stream pc and mac with pc being the gaming device and macbook being the streaming device? Currently using M4 chip and was looking to buy stream deck + and capture card 4k s
Should be fine yes - though that's a better question for #capture-cards . Only thing I would generally note is macOS can't capture HDR live from the card as it doesn't support P010 in the macOS UVC driver (though you can still game in HDR and the card will tone map to SDR there might be colour shifts).
Ok lemme ask thanks
Where can I find that mount for my wave:3
that mount u get for ur desk stand is broken on mine
I'm not seeing the base plate right away, but you can get everything else here: https://www.elgato.com/us/en/s/spare-parts
okay
its not in there, in trying to find this
I have to tape it to keep it in place
I wanna buy a arm but I first have to know if I still need that part to mount the arm
yes U frame
It's on there
is there any place I can get that part
oh
I couldnt find it, ill look again
oh found it
thanks
One Wave:3 user got that u-frame 3D printed in PETG
i dont have a printer
Makes sense
Well for the time being I used superglue to stick the 2 parts and the desk stand together
do u need the u frame for those shock mounts?
I have no idea cuz I don’t have a Wave:3
okay
hi
hi, did you need help with something from the marketplace?
Why does the marketplace constantly boot me back to sign in?
Hmmm I think the sync from stream deck is also broken for me.
Clicking on view account via Stream Deck goes to a 404 page.
None of the things I "Get" from marketplace shows up on my stream deck. Tried uninstalling / reinstall / rebooting computer. Log in and out. Nothing helps.
did you clear your cookies, etc?
did it for me too when i was setting up my stream deck, really annoying
used a firefox fork so that could be something to do with it, maybe plays nicer with chromium
Yes, it was doing it on a different browser on a different computer too. By the next day I was able to access it again without issue though.
hi
Hi guys, is there any free plugin in elgato wavelink 3.0 market place for audio to make voice deeper, I just cannot get it right using Elagato EQ
Any help is much appreciated
Please add a clipping button for the discord plugin! PLEASE!
Feature requests go to #feature-request - there's a link there to sumbit them. This is a community help channel which is usually users so you want to make sure that those requests go to the right place.
Keep in mind as well that the Discord plugin is limited by actions allowed by the Discord API. As Discord doesn't do clips without Nitro this might not be part of their API.
There is a clipping keyboard shortcut though (that's customizable), so you could just set that up and bind it to a hotkey action on your deck.
Ah yeah i already submitted it through mail xD
Thanks tho
Good luck with it!
Guys, do you have a good plugin for beamng? I dont wanna buy plugins whe n i dont know how good they are
when i try to pay on the marketplace it says "We couldn't complete the purchase for you. Try again in a moment." i have tried it half an hour later and it still diddnt work has anyone got a solution
yeah, the solution is to call ur bank and see if u got enough cub on it
or if ur blocked
for using ur card
If it doesn't resolve after I'd also suggest reaching out to support through #official-tech-support . They can get you to the customer service team to look into it.
is there a plugging that works with stream stickers i use on my twitch save keep using my phone to pick a stciker to use /throw
Hey. Why i cant download Spotify Elgato Plugin ? If Someone could help me
Hi peafox, can you tell me what operating system and Stream Deck version you are on?
Sorry, I forgot to delete my message. I restarted the app and it worked lol
Is there a mic mute plug-in that has hold ptt and has customisable activation and deactivation sounds?
Or a way to edit an existing plugin
Maybe use something like the mic mute plugin or BarRaider's WinTools in a multi action with soundboard?
I can't seem to get a multiaction to do 2 things on press and release
that's my only hurdle with that method
Are Elgato services down?
I cannot login and I am sure my login credentials are correct. Highly doubt an Elgato account of all things was hacked.
Elgato are having tech issues lately especially with streamdeck, either server or software update related , maybe both
Why cant i authorize my discord with elgato discord plugin?
any solves on audio latency delay with elgato studio? both pass through and recording have an audio desync issue where audio slowly desyncs from video
That's a question for #stream-deck , but the usual troubleshooting for that is:
First check that Stream Deck itself is up to date, and that the plugin in the settings is also up to date (Stream Deck is currently 7.4.2, and the plugin is 2.2.0.98). Also Discord itself should be updated. If you have more than one Discord account setup on the same PC check if you previously authorized it on a different account as well.
After that, the usual fixes for Discord auth issues, are first to remove it from the Discord authorization settings in that app, and add/test it again by re-adding the action to you Stream Deck to see if it at least pops up.
If that fails:
Uninstall Discord, rename the %appdata%\Discord folder to something different, and reinstall it. This usually fixes a repeating authorization issue. Don't actually delete the old folder in case you need to put it back, or have to get support involved as it contains useful logs. This should prevent Discord from getting tripped up in leftover data from previous authorizations can can cause it to retrigger. Rebooting between the uninstall and reinstall is also required to make sure none of the old files or settings are locked open or still resident in memory.
Failing that if it still keeps resetting the authorization or failing to authorize, back up your Stream Deck profiles, and note installed plugins, uninstall the app, then rename the %appdata%\Elgato\StreamDeck to something else before reinstalling so you keep the logs in there, but the app doesn't find any old settings. (This is assuming for PC. MacOS it's probably in the application support library for the same files.)
You probably shouldn't make it to the end of that list and still have issues but if it doesn't work past that, reach out to #official-tech-support and file a ticket through the chat system on the website or call in the number on the link in that channel.
That's a question for #capture-cards - but Studio should not get getting desync. Passthorugh to the HDMI OUT definitely should not as that signal is supposed to pass through the card unmodified - getting delay on the passthrough implies an issue with your source (Make sure you're not confusing passsthrough to the HDMI out port, with preview which is what you view in the app, as these are different things). Check that whatever you're recording from is set to Stereo or Linear PCM, and if it has a sample rate setting 48,000 Hz.
