I have a first-gen MacBook Pro (MacBookPro1,1) with an hda soundcard.
Sound does not play through the internal speakers.  Instead, I need to
hook up speakers to the headphone jack.  This laptop runs recent
- -CURRENT, and this has never worked.  The mixer reports:

Mixer vol      is currently set to  75:75
Mixer pcm      is currently set to  75:75
Mixer speaker  is currently set to  75:75
Mixer line     is currently set to  75:75
Mixer rec      is currently set to   0:0

A verbose dmesg can be found at
http://www.marcuscom.com/downloads/gyros_dmesg.txt .  The snd_hda module
is loaded from loader.conf.

I saw a few reports about sound on BOTH speaker and headphone, but this
is just headphone.  A previous commit (rev. 1.12 of hdac.c) made me
think that this sound work, though maybe only for the MacBook (not Pro).
 Any suggestions?  Thanks.

Joe
