Audio stuttering on many Proton games ChimeraOS that had no issue before. (lemmy.ml)

I have been using ChimeraOS on my living room PC and it has worked well most of the time without issues. Recently I had audio stuttering on a new game and fixed it by using an older Proton build. But then I started a game that I have played many hours on this machine without any issue and suddenly had audio stuttering again on this title that previously had no audio issue with. Then I realized it is a problem with most of my library... This is really annoying for some title.

Anyone experienced something similar recently ? I have updated ChimeraOS twice since and updated the Proton Experimental build etc... Don't know if it is related to Proton, to a driver, to Chimera... How could I debug this ?

I've had a similar problem across various distros and several years: everything is fine for a while, then suddenly several games have audio crackling issues. I can usually (but not always) solve this with a PULSE_LATENCY_MSEC=60 %command% in the launch options; sometimes a different number, such as 20 or 30, works better.

PIPEWIRE_LATENCY=1024/48000 %command% if using pipewire. You can change those values as needed.

+1 on latency being an issue/solution
