Describe the bug
I thought I would open this up again considering the oldest issues regarding this are over a couple years old

Right now per this issue, I'm not able to get audio output working on the valve index. The microphone fully functions, but the speakers do not show up as a selectable configuration

On pavucontrol-qt the two options I have are Pro Audio and Mono Input. (Currently using pipewire), as of a couple of years ago it sounds like people were able to use pipewire previously with the valve index (with the lack of automatically switching over)

I've yet to test pulseAudio with the index, would be fine with testing it, and am interested in doing that next.

Things I've tried:

1. on the latest nvidia drivers
2. setup the USB rules as seen here
3. Ran the Steam VR beta
4. Ran the base version

I've also tried running with X, but that didn't really do anything, and I figured it wouldn't.

To Reproduce
Steps to reproduce the behavior:

1. Launch Steam
2. Launch Steam VR

Expected behavior
Valve index provides an audio output device on pipewire to manually switch to
