Description of problem:
on a dell d620 and an x200 (ich7 and ich9) i cant figure a way to enable the microphone in jack. both are using snd-hda-intel. internal microphone on the d620 works fine. i am not sure if alsa or pulseaudio is responsible. if necassery please reassign.
the internal mic of the d620 is the default capture device and works (although it is not very loud)

outut of alsa-info on the dell d620:

I have the same problem on a Dell Latitude D820, first reported in https://bugzilla.redhat.com/show_bug.cgi?id=477888.

I had been using a line-in, powered stereo microphone under Fedora 8.  I upgraded from 8 -> 9 -> 10 (did not test at 9, only upgraded as part of the upgrade to 10) and lost sound.  Bug 477888 resolve output issues, but the input selection does not work.

My alsa-info.sh output is at

it would be nice to get points what to do next to get the issues resolved.

The intended way to switch sound input devices is the device list on the input tab of the sound capplet. 

Does that not work ?

After a bit more research, I seem to be able to select between the built-in microphone and the microphone jack.  I am offered two choices: "Mic" and "Front Mic".  I have lost the Line-in choice that Fedora 8 had/.
