No Audio

[Karutamaru]

Yesterday, Steam VR was working just fine until it wasn’t. Now suddenly it has no audio whatsoever. None in the Steam room and none in the games. My Meta Quest 3’s audio works fine, but in Steam link/vr, it’s all muted.
I have tried everything. I spent 2 hours looking at everything audio-related. All devices are enabled, all audio is maximized, I tested switching to every single headphone option manually and verified the Steam VR files. By every single measure the sound should be working, but it just won’t. What else can I possibly do?
