when I updated from kernel 6.0.12 to 6.1.1 the audio playback with my USB audio interface, the Behringer UMC204HD, stopped working. When I want to watch a video on YouTube with Firefox the video only plays for 1 or 2 frames and then stops. When I open a .mp3 with mpv the track stays at 0:00.
The audio interface is recognized though because it shows up in my KDE audio icon as the UMC204HD and I can switch outputs from Line A to Line B and so on.
I have read about HDMI audio issues with kernel 6.1 and I thought this might be related, so I waited for a fix on that. This fix came with kernel 6.1.2 but sadly this did not solve my problem with the Behringer.
Audio works fine on kernel 6.1.2 when I use my other USB audio interface, the Yamaha AG03, or HDMI audio from my RX 6700XT.
When I downgrade to kernel 6.0.12 the Behringer interface is working again, so I’m sure it has to be a kernel issue.
Anyone else has problems with this Behringer interface? Is this a known issue?
I did try that just now and sadly it made no difference.
I actually needed implicit_fb=1 with kernel 5.x because without it I also had choppy sound with the UMC204HD. Starting with kernel 6.x I had clear sound without this tweak.
