Audio stopped working on SteamVR games (Beat Saber, Knockout League, SuperhotVR...) at one point, for no identifiable reason.
I've tried most of what there is to try on Windows and SteamVR settings, changing playback devices, mirroring settings, reinstalling USB drivers, nothing works. Sound plays neither on the computer nor in the headset. Here's a full system report from SteamVR : https://pastebin.com/dBXVi8Gh
And here's a screenshot showing what I believe is the root cause of issues, some Vive USB seems to have stopped working.
If anyone has an idea about what I can do about it, you'd be my savior !
