I got a new Hisense 55 inch TV the other day and plugged up my laptop. Audio coming from laptop speakers is fine but when I switch the audio output to the TV, I hear no audio. How would I go about fixing this issue?

#

I am not getting a dummy output.

#

how are you connecting it?

plucky aurora May 14, 2026, 10:36 AM

#

HDMI

#

#

I dont really know how to screenshot the primary screen

#

plucky aurora I dont really know how to screenshot the primary screen

there is a screenshot app that lets you screenshot only the program's window or section of it

#

Also check TV's volume level when hdmi is connected

plucky aurora May 14, 2026, 10:51 AM

#

I have. The volume is up and I have went up higher as well

#

So, when you play a video or something, while hdmi is connected, there is no sound anywhere?

plucky aurora May 14, 2026, 10:53 AM

#

Yeah, no sound. I even tried the Sound Test and nothing comes out

tidal rampart May 14, 2026, 10:55 AM

#

Are there other output profiles you can select on HDMI connection?

plucky aurora May 14, 2026, 10:56 AM

#

I have tried all of them, 5.1 to 7.1 and nothin

tidal rampart May 14, 2026, 10:57 AM

#

Did you check the cable itself? Does it transmit sounds when connected to other devices?

plucky aurora May 14, 2026, 10:58 AM

#

Thats a good question

#

I am pretty sure since it is a new one

tidal rampart May 14, 2026, 10:58 AM

#

Check anyway if you can

plucky aurora May 14, 2026, 11:01 AM

#

Yeah

#

It does support it

#

Would it say the name of the TV for the speakers now thinking about it?

tidal rampart May 14, 2026, 11:05 AM

#

If you have a windows laptop or something, can you test it there? If it works on windows then it's likely not the TV or cable part that's the problem

plucky aurora May 14, 2026, 11:06 AM

#

Dang I do not

#

I could try my Switch 2

#

Yeah I am getting audio

tidal rampart May 14, 2026, 11:14 AM

#

Audio from the notebook on the switch? Or the other way around?

#

Or did you mean switch audio on tv?

plucky aurora May 14, 2026, 11:22 AM

#

There is audio coming from the TV when I have it plugged into my Switch 2

#

With the hdmi cable

tidal rampart May 14, 2026, 11:26 AM

#

Are there multiple hdmi ports on the laptop?

plucky aurora May 14, 2026, 11:30 AM

#

Just HDMI and DisplayPort

tidal rampart May 14, 2026, 11:33 AM

#

Ok, open the terminal and show us the result of these commands (with hdmi connected and selected)

inxi -GAxxx
pactl list short sinks
pactl get-default-sink

#

I got it to work

#

I just had to close my laptop

tidal rampart May 14, 2026, 11:35 AM

#

Close and open the lid?

plucky aurora May 14, 2026, 11:36 AM

#

I think i will just keep it closed because I dont really need the laptop screen for anything

#

I have the laptop sitting down here

tidal rampart May 14, 2026, 11:38 AM

#

I don't get it. Why did you need to connect tv to a laptop if you keep the laptop closed?

plucky aurora May 14, 2026, 11:38 AM

#

Waaait I understand whay is going on.

#

The audio wasnt working because I was watching it at 1440p which doesnt have audio support for this TV I guess?

#

But when I had it at 4k or 1080p the audio was working

tidal rampart May 14, 2026, 11:42 AM

#

.... Why would it not work at 1440p when it works at 4k which is higher?

#

I don't understand the situation anymore, but glad it works for you.

plucky aurora May 14, 2026, 11:43 AM

#

Actually it might be the cable

#

Thanks. Sorry I might be a bit silly

tidal rampart May 14, 2026, 11:45 AM

Alright
