Which is what *should* happen. After all, when you plug headphones into
the proper jack, it's a sort of 'signal' that you want to hear something
without disturbing all the people around with it too :)
When I asked:
"Is automute of headphone/speakers always handled by the snd_hda
driver?"
Ariff explained why this happens to me by writing:
"It all depends on the internal wiring, codecs, vendor preferences,
etc, but mostly yes, it is handled by the driver itself: cheaper,
flexible."

Try contacting Ariff. He is pretty responsive and he will most probably
reply with a patch that fixes the problem for you. This is *exactly*
what happened when I asked him about my own laptop, a Toshiba Satellite
U200, which had the same 'bug'.
The fix for my laptop is now part of FreeBSD 7.0-CURRENT:
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/sound/pci/hda/hdac.c?rev=
=3D1.21&content-type=3Dtext/x-cvsweb-markup
Before contacting Ariff, it will be helpful (and will save you at least
one round-trip of email exchanges), if you boot in ``verbose mode'', and
save a copy of ``/var/run/dmesg.boot''.
Then, make sure you include this file and the output of ``pciconf -lv''
in your report.
Good luck,
Giorgos
