Oh yeah, sorry, I forgot to add that.

Does ext-mic pin (0x18) jack-sense work with hda-emu at all?
When this pin is selected, the recording is done via another ADC
(0x15) instead of the one for int-mic and dock-mic (0x14).
Try to reopen the recording stream when you plug the ext-mic.
It might be a bug in the dynamic ADC-switching of the running stream.

This is an issue in alsa-lib (and remaining intentionally), no driver
problem.

It should change the headphone auto-mute behavior.
The speaker will be always turned on.
