I'm spectating a game and initially had no audio. I toggled sound devices and tabbed out and back in, and then toggled various audio settings off an on again and was rewarded with music starting to play and with pings making sounds, but I've got no other in-game sounds and there's a constant feed of sound errors at the top of the screen, listing what looks like the ids for all the in-game sound effects.
Is there a fix for this beyond restarting and hoping? Some sort of game file validation, perhaps, similar to what you might do with Steam if you saw similar, or is it an audio engine issue without a user-facing fix?
