Enable USB Audio Jack Detection

Steam OS supports USB Audio Class 2.0, which allows for jack detection, but this does not currently work with Steam Deck. If you plug in a UAC-2 audio device with jack detection, Steam Deck will default to using it for input and output, even if these jacks have nothing plugged-in (checked with devices that are confirmed working correctly with Windows and macOS).

Ideal behavior would be to not allow the use of "not plugged-in" USB audio devices since the main reason to support jack detection is to eliminate the chance of unwanted audio device switches to devices that aren't in-use (for example, plugging in an external sound card or dock and only using the headphone output but not the microphone input).

Ummm.... Are you sure USB audio jack detection can be serve with generic usb drivers?

Are you sure that your device does not need device specific driver?

[/code]lsusb -t[/code]

It seems like all hardware have various patterns of brokenness.

Yes, I am sure. The device used to test was a HyperX QuadCast 2 S, which is a UAC-2 audio device with jack detection for its built-in headphone jack that does not use any custom drivers (I work as a test engineer for HyperX, so I've done a ton of testing with this kind of stuff on a large number of platforms, but I'm submitting this personally, not on behalf of the company).

The audio device has no problems enumerating and using the playback and recording endpoints. The only part that isn't working is the jack detection.

I am not sure whether Valve modifies Wireplumber. I believe Wireplumber handles Jack detection etc. I personally do not need to touch it.

I believe this directory holds the scripts

ls /usr/share/wireplumber/scripts/

I believe you can get the installed file list with this command

pacman -Ql wireplumber

Here is the upstream link to wireplumber.

Here is the arch wiki for wireplumber too

I do not know which route you choose to take. I hope Valve does take a look at this issue or try to contact you. I hope your issue is resolved.

I do not have enough information to validate to deny your statements.

Good to know, thank you! I'll check it out when I have a chance.

Totally understood on not having enough information :). UAC-2 devices with jack detection are still very rare (it's been very difficult to find other products to validate against lol).
