This is fairly long, so I have it included as an attachment.

I'd love to do this, but:
atrophy:/etc/modutils# amixer -c1
amixer: Mixer load error: hw:1
atrophy:/etc/modutils# alsamixer -c1
alsamixer: function snd_mixer_load failed: Invalid argument

Hmm, when I load snd-mixer-oss and snd-pcm-oss, only /dev/dsp appears as a
compatibility link to sound/dsp. Sound (which im guessing is the oss stuff in the dev
tree) has:
mark@atrophy:/dev/sound$ ls -l
total 0
crw-rw---- 1 root audio 14, 4 Dec 31 1969 audio
crw-rw---- 1 root audio 14, 10 Dec 31 1969 dmfm
crw-rw---- 1 root audio 14, 9 Dec 31 1969 dmmidi
crw-rw---- 1 root audio 14, 3 Dec 31 1969 dsp
crw-rw---- 1 root audio 14, 2 Dec 31 1969 midi00
crw-rw---- 1 root audio 14, 0 Dec 31 1969 mixer
crw-rw---- 1 root audio 14, 18 Dec 31 1969 unknown
Which I guess makes sense since oss only supports one audio card and I
have two . . .

There is only a stream0:

The two devices popping up seem consistant with the hardware, it has a
midi in/out (no thru).

Thats ok, wavetables suck. I'd rather hook up my own bank via midi, heh.

As shown above, amixer doesnt want to fire up. I hate to do it, but
here is a wishlist:
- have the volume knob on the front of the device work
- be able to turn "cmss" on and off either via the controling client or on
the hardware itself. (its a dsp that fakes surround sound fairly well).
- be able to control the output detection of the unit. apparently it
can tell if you have 2, 4, or 5 speakers hooked up into it. the option
can certainly be automatic (testable when i unplug the card and use it
as a standalone), and I'm fairly certain it can be forced as well (as
evidenced in windows). When I was able to use the hardware with the
current rc release of alsa, it forced 2 speaker selection.
- the remote ir stuff is cute but not really essential -- would be nice to
have hooks to attach triggers to or something.
It's a really tall list, but its just so know where I'm comming from
and where I ultimately want to head with it. I'm more than happy to
help you take me as far you're willing =p
thanks,
