Re: [Line6linux-devel] UX2 - sysinfo

Okey, now i have tried everything I could think of and I'm not getting
anywhere. When I'm trying to record with audacity and ALSA I cant get any
sound from the input. And when I use jack it seems like it instead uses the
microphone on the computer. But I can see it with alsamixer and i can
change the input.

One more thing is; I cant start up computer if device is plugged in. Some
sort of error and it goes to text-mode, and then I have to restart without
the device. But all seems right if I plug it in after startup.
