I have some trouble with my USB sound card 68878 from goobay.
Alsamixer showing unexpected devices
Secondly when I use alsamixer displaying Playback items. I see both a Speaker and a Mic:
For Capture I see a stereo item called Mic:
I would expect to see both a stereo mic and a stereo speaker, without the Mic in Playback
Flipped labels?
When I run speaker-test -D hw:1,0 -c2 my mic suddenly emits noise.
Additionally all images I've seen on the internet there the yellow plug is the mic and green for the headphones. This is flipped as you can see on my photo:
The problem
So at the moment I can only playback and record audio from the green plug. I haven't been able to play any audio out of the yellow jack.
How do the items I see in alsamixer correlate with the hw:1,0
