Hey there,
I was quite happy to receive my UR22 MKII, it was also immediately found by my laptop, but I don’t get any sound … when I select it in “alsamixer”, I’ll get this:
[Clock Source 41 Validity]
What am I doing wrong here? And, does it work with the ALSA driver, or should I choose Pulseaudio or Jack? I really don’t know what to do. Help appreciated!
(I also created a similar thread in the arch linux forums, maybe I’m being too impatient, but there has been no reply yet, so I hope at least someone on here can offer some advice)
My system:
$ aplay -lL
