No audio on Linux and mysterious Olympus crashes

[grand lark]

When I launch Everest or Celeste, no game audio plays. On my Linux desktop, it doesn't show Celeste as an app that is playing audio, which makes me think that it has something to do with SDL/GLFW/etc. or whatever Celeste uses to talk to the OS and play audio/show graphics.

The Olympus crashes is as follows:

1. I launch Olympus
2. Everything is fine
3. Some time later, Olympus completely disappears, not to be found anywhere in btop (htop but not quite).
   Sometimes, I get an error message (on a blue screen), shortly after launching (was unable to capture the exact message)
   And finally, Olympus sometimes just stops responding, very shortly after launching.

Of course, it's all terribly inconsistent, and sometimes none of the above cases occur.

Thanks for your help!

can you send celeste's and olympus's log files?
olympus's ones are in ~/.config/Olympus; celeste's are next to celeste.exe

[grand lark]

ok

what should the filenames be for Celeste's

oh wait

for Olympus, just log.txt?

there's a lot of error <date> folders
