[SOLVED] Unable to get sound output to Valve Index headset

I've been struggling to figure out why my Index isn't receiving sound. I know that the hardware works, because it plays sound when I use it on Windows. I have no other audio problems on Arch that I'm aware of; My headphones play sound just fine.

aplay -l lists all of the outputs on my graphics card (where the Index is plugged in), but it is weird because it lists the displayport slots as HDMI. I haven't yet figured out if that matters or why it's doing that.

I've identified which card and device the Index should be receiving sound through (and tried another possible one just in case). I've tried running speaker-test to it, but there's no sound output. When speaker-test runs for the Index, the terminal output looks like this:

speaker-test 1.2.10

Playback device is hw:0,9
Stream parameters are 48000Hz, S16_LE, 2 channels
Sine wave rate is 440.0000Hz
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 1048576
Period size range from 32 to 524288
Using max buffer size 1048576
Periods = 4
was set period_size = 262144
was set buffer_size = 1048576
 0 - Unknown
 1 - Unknown
Time per period = 10.935558

This is exactly the same as when I run speaker-test for my headphones, except instead of "Unknown" my headphones show "Front Left" and "Front Right".

I don't know what the issue is or how to debug further. Any help or advice is appreciated.

Re: [SOLVED] Unable to get sound output to Valve Index headset

If anyone else has the same problem as me and finds this thread, the issue was that the Index is normally in "standby" mode. It does not show up as an audio output until it exits standby mode. At the moment I'm not sure how to do this other than loading up SteamVR, but once I started SteamVR the Index showed up in aplay -l and I was able to configure it for sound. The audio was weird and fuzzy at first but after I rebooted my PC it started working fine.
