HDA sound problem on mac pro running -STABLE

I have a mac pro running -STABLE from a couple of days ago.

If I load the sound and snd_hda modules I can play an mp3 file with
mpg123, BUT even with the mixer vol and pcm set to 100:100 it's only
just barely audible.

There's dmesg and sysctl info at:

  http://shrimp.alerce.com/misc/delicious-sysctl

I've tried picking up Ariff's binary modules, and I've tried setting

  hint.pcm.0.softpcmvol=1

and 

  hint.pcm.0.config="softpcmvol"

using kenv and then reloading the driver, with no improvement.

Anyone know how I can get the volume to behave?

Thanks,

g.
