HELP MEEEE

[ENASUPREMACY]

So I haven't been using steam in a while, lets say, a year, and I go to play the stanley parable (amazing game) and I HEAR NOTHING, so i play ultra deluxe and SAME THING. And i think all my games have this so i go and play bugsnax and i hear perfectly? So now, almost all the games i like to play are weird, and i cant play anything now. :( (PS: this does persist with new games as well, as i am trying to play a game - PLEH! - and it is the same muted problem as well, but the weird thing is, another game i just got, a demo for Bits and Bops, works perfectly? If anyone knows why this is happening please help!)

[ReBoot]

With that game running, open the volume mixer. Entirely possible this game's muted.
