Comment 22 for bug 571294

@Snake, have you tried dealing with alsamixer?
In my case, opening alsamixer and hitting F4 shows me the recording
controls, one of which lets me choose between input sources, using the
up and down arrow keys.
To open just type "alsamixer" into a console, without the quotes. Then
navigate with arrow keys and F3, F4, F5.
Cheers!
