Public bug reported:

To begin with I only had stereo output. When using alsamixer to change
volumes, I can get 5.1 sound output. But no matter what I try, it
doesn't seem possible to get my mic recording anything. Other than the
mic, everything seems to be working now. In Windows 7 - everything is
working great, checked and double-checked.
