Hi, same problem here.

I'm on a HP Pavillion tx1499us
with snd-hda-intel (name nVidia Corporation MCP51 High Definition Audio (rev a2))
(Chip Realtek ALC861-VD according to alsamixer)

- Release: Ubuntu 10.04 LTS
- pulseaudio: 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu14
- alsa-base: 1.0.22.1+dfsg-0ubuntu3

In my case, gnome-volume-control offers only one choice for "sound input":
"Interanl Audio Analog Stereo"

But the internal mic is not working, only external mic works connected to jack.

In my case I've found a different workaround than fab, I just opened alsamixer in a console, went to the Capture tab with F4, and there it was the "Input Source" selector, letting me choose between "Front Mic" (which corresponds to external jack) and "ATAPI Mic" (which enables built-in mic)

After choosing "ATAPI Mic" in alsamixer, no change is seen in gnome-volume-control , but internal mic works as expected.

So in my case, the snd-hda-intel driver seems to behave correctly, but seems like gnome-volume-control is "oversimplified" and doesn't show all the available switches (while they do appear in alsamixer)

Cheers!
