Comment 113 for bug 946232

@diwic, thanks for the answer. I tried inserting the line as suggested and rebooted. My microphone inputs (both the internal mics and the mic jack) disappeared entirely, with "Line In" as the only remaining option. "model=dell" was also ineffective (it had the same behaviour that I described above).

This is with the latest alsa-hda-dkms and the pulseaudio patches. I have rerun the alsa-info script and attached the results.
