Some games and all Proton games always fallback to the default audio card.
When I run a game in Steam with Proton, change the audio card to my headset, it will always fall back to the default audio card on the next launch.
This also happens with some native games, while most work fine. For example, Valheim (which uses FMOD Ex App) will always fall back to the default audio card, while Terraformers (which uses FMOD Ex App as well) remembers the state. BUT when Valheim changed the state, it also changes it for Terraformers.
I'm not sure how I could provide more helpful information, please guide me.
