internal mic does not work on Fujitsu P7120

Binary package hint: pulseaudio

On my P7120, running 10.04 final RC, my internal microphones (stereo mic) do not give any signal in sound properties, nor do they record in any application. They work fine in Windows, so the problem is software/driver related.

This seems to be first reported in bug #62891 however that bug was marked invalid, seemingly due to a number of problems reported in the one bug report, many of which were resolved. This one was never resolved however.

I *did* find the following on the redhat forums, I'm not sure how to implement it due to us using pulseaudio rather than alsa, but hopefully if someone could give me some tests to perform using this info, it would be most appreciated!

Workaround:

I am using FC12 and its included alsa driver (1.0.22) on my Fujitsu P7120. I
can use Skype with the built-in mic and headphones by using:

In /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel model=test

Then before running skype:

% amixer --stdin << EOF
sset LOUT2 0% mute
sset LOUT1 60% unmute
sset MIC2 60% unmute cap
sset 'Input Source' 'MIC2 pin'
sset 'MIC2 pin mode' 'Mic 80pc bias'
EOF

That seems to effectively mute the onboard speakers (LOUT2), unmute the
headphones (LOUT1), and unmute/capture the onboard mic (MIC2).

I don't know how to tell alsa to use this configuration "by default", and I
don't know how to have alsa automatically mute the speakers and unmute the
headphones when I plug headphones in, and do the reverse when I unplug them. I
bet it's possible (via .asoundrc?), and I'm just ignirrint.

I'm not sure which pin complex the Mic jack is connected to on the P7120 (I
suspect MIC1).
