Yes... let me go ahead and re-hash this for those who don't want to read
through the earlier email.

Sagi and I have two different soundcards with somewhat similar, yet
different, problems.  (Ambigious enough?)

His soundcard theoretically supports hardware mixing both in actual
hardware and in the ALSA drivers, yet when he tries to open a second
audio stream, the application attempting to do so simply hangs until the
resource is free.  I think he said his card was a GTXP... I am
unfamiliar with it.

My soundcard also supports hardware mixing, but only in the hardware..
not in the ALSA drivers.  Perhaps two threads would be ideal.  Oh well. 
I'm running on an nForce board using its integrated audio.  The drivers
nVidia provided (for OSS) simply consisted of an Intel i810 audio
patch.  I guess y'all on the ALSA team were able to utilize the
nVidia-released patch and do the same thing to the ALSA i810 drivers.

Anyway... Sagi needs to know how to get the multiple streams working on
his card, globally.

I need to know if it is possible to get the nForce (using the patched
i810 driver) to support hardware mixing so I can send many audio streams
to it at once.  I have basically no programming experience, but may have
a few friends who could help me if I had some clue of the how or the why
of it.  Alternatively, since I cannot afford to send anybody hardware...
if somebody was really interested in working on this, I could give you
ssh access and work with me, here, physically... but I don't know how
useful or feasable such a thing would be.

Anyway... input on either or both topics by you guys who really know
what you're doing would be much apperciated!  :-)
