Yeah, I have tried all the basic stuff.
At this point, I've basically accepted that solving the problem on my
machine is going to involve a whole bunch of technical stuff that I
don't have the patience for - reading the HDA spec and the codec
datasheet, reading the driver code, and making changes to the driver
and default settings where necessary. (The hardware does work fine
with the Linux kernel.)
So yeah... that's probably never going to happen. I'm still wondering
where the numbers in the names for the device special files come from.
And thanks, Frank.

It seems to me that under /dev, you can have the following

dspX.Y

I'm having some trouble getting my sound to work (Dell Inspiron
E1705/Inspiron 9400 with Sigmatel STAC9220 codec). I've read the
manpages for snd and snd_hda (which is the appropriate driver), and
increased the verbosity of the drivers and read the kernel log and
/dev/sndstat, but I still can't quite wrap my head around everything.
What I'm wondering is: what exactly is the meaning of X and Y above?
I'm assuming that X comes from the association numbers in the
snd_hda driver, but I could be wrong. Please correct me!
Thanks,

Have you tried setting the default unit:
# sysctl hw.snd.default_unit=1
If that works, you can make it permanent with:
# echo hw.snd.default_unit=1 /etc/sysctl.conf
If it doesn't, you have to post the output of:
$ cat /dev/sndstat
Make sure your volume is turned up: mixer(8)
HTH.
