The beautiful games I own are Snake Pass and Sonic Racing Transformed, both of which have sound issues (muffled audio) when played through a cheap soundbar via bluetooth, audio for all other games with this soundbar works perfectly.

I’m on EndeavourOS (Arch Linux) using repository Steam, KDE Plasma and Pipewire. I’ve tried all the different proton versions (experimental, 9, 8, 7, 3, etc) without success. Maybe I could solve it by removing pipewire but I don’t think it’s worth worsening the entire OS, since it’s only about these two titles.

Q:

• The problem seems to not appear on other distros, like Debian (maybe due to different packages / pulseaudio?).
• Coincidentally it only happens with these two SumoDigital games, could proton be missing some component commonly used in these games?
• Since I can’t find any relevant solutions online, I assume that the problem only exists with this type of Bluetooth audio device.

[edit] AtM I “solved” it by connecting the speaker via cable.
