Hi, I don't know if my problem is with XAudio2, but the symptoms are the same.
Since Friday 30/05/2025 games that work via proton do not play sound, but native games like Nordhold (3028310) do work.
i should edit the title/issue, it's not specific to xaudio2, i've had it happen in dome keeper, a godot game, which has a native version (native version launches without sound, proton version crashes on launch)
Issue still happens with pipewire 1.4.4

pipewire issues: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4715 & https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4722
Issue is related to 5.1/7.1, to fix it while problem is being worked on, switch your audio ouput to stereo
I changed the audio output from 5.1 to stereo and it works, thank you!
