Automute actually works for a select number of cards.  The problem is
that instead of querying the card for the info the automute feature
needs (which speakers to mute etc.) the driver looks up the values in
a lookup table.  The lookup table only has 10 or so cards in it.  I
added values for my card/codec into the lookup table and automute
worked fine.  I'm going to try and update the auto mute to get rid of
the lookup table.  After that if I'm feeling ambitous, I'll try to
update the driver to have some of the bells and whistles of the
freebsd driver.
Bug #2090: snd_hda does not support headphone automute

Author: Justin C. Sherrill
Status: New
Priority: Normal
Target version: 

The hda sound driver does not notice jack insert/removal events.  Even when
booted verbosely, there's no action, so attaching headphones does not mute
speaker audio.

An update to FreeBSD's sound/pci/hda expressly mentions solving this problem:
