[TF2] [Linux] Voice chat not working

[TuukkaMA37]

I have been having issues with voice chat on Linux. Voice chat perfectly fine on Windows, which I have a dual-boot setup for.

Audio in Steam works for other games, having tested with a friend in Dota 2 and non-native games running under Proton, and even on the mic test screen in game. Upon using voice_loopback 1 in console, I can hear myself as well. However, other voices are shown with flickering graphics and no audio. Testing in-game in TF2 with a friend, not only could I not hear him, but he described my voice input as "garbled static". My audio driver is PipeWire, with the pipewire-pulse device as well as 32 bit libraries for PipeWire being installed.

Occasionally it used to say "failed to load audio codec "vaudio_celt"", which the command "sv_voicecodec steam" fixed, but still presenting the above issues. It mentioned something about the userconfig.cfg file being missing, but even a deletion of the cfg file in the files and validation replacing them with original shows no change. A clean reinstall of the game has remedied the failure to load the audio codec, but past that there has been no change.
