Hello @arrowgent, why do you suspect that this is a Pressure Vessel / Steam Linux Runtime - Soldier issue instead of a Proton issue? Is there a change in behavior between running games with Proton 5.0 (and older) and Proton 5.13 (and newer)?

[arrowgent]

the games im testing do not work with proton 5.0

if you have a suggestion for a game with voice audio that does not require proton 5.13 (and is free) i will give it a test.

the other game i tested was https://store.steampowered.com/app/408900/Unfortunate_Spacemen/
