Bug Description
On a dell xps m1530, the line input jack doesn't work on Karmic 9.10 (same problem in previous Ubuntu versions). With the command alsamixer there is a switch between 'Line In' and 'Mic in', but in both cases, audio is recorded from the internal microphone of the laptop.

I found a solution:
run alsamixer in terminal, then set the 'digital' switch to analog (the 'front mic jack mode' switch doesn't do anything, as one might think). Anyway, I can't find this option/setting in the gnome-volume- control app.
another thing:
if I run gnome-alsamixer, I can see a 'digital input source' switch, which doesn't do anything and the terminal gives:
** (gnome- alsamixer: 4925): WARNING **: gam_toggle_ get_state (). No idea what to do for mixer element "Digital Input Source"!
