Audio interface disappeared from Sound panel

Hello,

I have a Behringer UM2 USB audio interface for my microphone input. It’s alsi an audio output devuce (although I just use for my XLR microphone).

It appears as:

PCM2902 Audio Codec

The audio interface was always recognised out of the box in Manjaro. But it suddenly disappeared from the Audio Settings / Input. The interface is now only listed as an output.

I’ve installed pavucontrol and can see the interface as an input device. I can seven select it as input audio in Discord, but not in Audacity and others. I tried to boot on a live USB drive of Manjaro and my input audio is recognised out of the box. So the hardware is functionning.

I don’t know what happened. All my software and kernel updates are disabled, it just suddenly disapeared after my lunch break. I’ve obviously tried to plug the audio interface to different USB ports, rebooted etc… Nothing resolved the issue.

Here is more info:

Can you please help?

Thanks

The kernel of the live Manjaro on my USB drive is 5.10-42-1. It’s not listed under the list of kernels I could install so I reverted to the 5.4.141-1 but it didn’t solve the issue.

You won’t get any result by bumping - other than closed.
