In space, no one can hear your game - KSP 1.10 No Audio

[nmd]

Hello everyone, I'm trying to get KSP to play audio on my linux computer but with no luck.

I downloaded a copy of KSP 1.10(.1.2939) from the website, but even when all of the settings in game have the volume up, there's no sound. Worse, if you go to desktop volume settings KSP shows up - you can raise and lower it's non-existent volume - so the computer knows something is suppose to be there.

I tried running ksp with a flag like so:

./KSP.x86_64 -force-glcore

But it didn't help.  I even tried setting some environment variables like so:

LD_LIBRARY_PATH="/usr/lib:$LD_LIBRARY_PATH" LC_ALL=C ./KSP.x86_64

But nothing. Doing both doesn't fix the problem either. I don't really know what to do next and searching leads to a dead end.

Weirdly enough KSP 1.9's sound works perfectly fine.

I'm running Arch Linux 64-bit with KDE (Plasma 5.19), a Ryzen 7 CPU (3700X) and a Nvidia 2080 GPU

Help

Uninstall/reinstall? Your download may have been corrupted in some way, so save your save games somewhere outside the KSP directory then uninstall and reinstall the game from scratch.

The first things I would try are a) testing with a new user account to eliminate per-user pulseaudio configuration, and b) disabling pulseaudio altogether, In which case KSP/Unity will fall back to traditional ALSA for sound.

I don't use pulseaudio myself (in fact I consider it bloatware), but I hear it's the default in Arch, so you'd want to hit up the arch wiki on how to debug and/or temporarily disable/bypass it for testing.

Other than that, a copy of Player.log might be interesting. IME it rarely contains any audio related info, but it wouldn't hurt.

It's a fresh install (downloaded from KSP's store)

I don't have any per-user pulseaudio config (only one user) but I decided to throw security out the window and run KSP as root. It didn't work

I ran

systemctl --user stop pulseaudio.socket
systemctl --user stop pulseaudio.service

And that didn't work either

I couldn't find a player.log, but there is a KSP.log, and I did find something interesting there:

Does anyone know what the FMOD::sound instance is? Is it relevant?

I know what FMOD is, but I've not seen that error before.

Probably.
