Public bug reported:

This may be related to Bug #538383

I have enabled my sound card with an init script like this:
#!/bin/sh
modprobe snd-hda-intel
echo '8086 3b57' > /sys/bus/pci/drivers/HDA\ Intel/new_id

This makes most features work, but the built in microphone still doesn't work. 
I have tried many combinations of the settings in alsamixer (switching to front-mic) etc. but I can't get anything to come through from the mic. 

I'm not sure if a newer version of the Alsa drivers is required. I'm
currently using lucid-backports (but not proposed).

Happy to test upstream changes if anyone thinks it will fix this problem
