Ok guys, try setting hint.pcm.0.config="novref" (using kenv) and
reload snd_hda (or using /boot/device.hints, but require a reboot).

If that works, well, that's good. You can ignore the rest of this
message or you may continue reading this and give me another round of
feedback after doing your own thorough test.

I put new source/binary module here (pick any of it):

http://people.freebsd.org/~ariff/test/hdac.c

http://people.freebsd.org/~ariff/test/snd_hda.ko

It provides "igain" control for microphone boost. Try playing with it.
