This doesn't seem to make a lot of difference. The external microphone is marginally better, but still not really usable (recognizable but distorted). The Gnome ALSA mixer shows 3 capture sources plus digital and 3 mux's. Only the first capture source records anything. I verified that you must have an external mic plugged in just to make sure the built-in mic wasn't recording.

I think the problem is that I set the dmux to ADC1MUX instead of ADC0MUX, could you test this patch to confirm? Please let me know your results.
Thanks,
