I've just installed the Alsa drivers for my Turtle Beach Santacruz card (CS46XX)
and everything is working fine except that I can not get surround sound
from it. I can see a device surround40 using "amixer -l" command, but I
cannot use the device to produce sound with aplay, even though I can
independently send sound to the front or rear spekers.
Any ideas what can be wrong?
Thanks in advance for any help.

It should be possible to have surround40 with the Santa Cruz card, with
"aplay -D hw:1,0" you should only have sound from the rear speakers.

Actually the drive that I use to send sound to the rears speakers is
"h:0,1" not "h:1,0". That's because the rear speakers controller is just
a subdevice of my first and only sound card. That works with no problems
sending sound only to the rear speakers but not to the four speakers.
I'm looking for a way to create surround sound using the four speakers.
There must be a way. Help please!
Thanks.

Oops! sorry for my misstake, I mean hw:0,0 -> front speakers and
hw:0,1-> rear speakers (assuming that you got only one soundcard
installed). In such way it's possible to control each speaker
independently, programs like xine can take advantage of this.
Then, whatever you want to do is just a software issue. It's not
possible to send the same output to front and rear just via a simple
"aplay ...", maybe it's possible to do magic via the .asoundrc stuff
crearting a virtual device, but I dont know how to do that.

the latest alsa-lib cvs tree already includes the definition for
cs46xx. you'll be able to play a 4-channel wav file like
% aplay -Dsurround40 4channels.wav

Yes I was able to play surround sound for first time. Very exciting.
Thank you for the good work pushing the penguin army to a more enjoyable
experience with Linux.
Sincerely,
Miguel
