Multichannel audio ?

Multichannel audio ?

[robinud]

Hi!

How does one use the extra channels on a six channel card ?
I can only hear the 2 front speakers.

I remember on a es1370 card, that I had an extra /dev/dsp1 for the rear speaker
pair, but with an on board VIA audio there is only one /dev/dsp.

I also tried playing a 6 channel sound file with sox, but still only the front
speakers make sound.

Any clues ?

HW is VIA 8235 + Realtek ALC650
kernel 2.6.8-debian
driver is OSS via82xxxx ( I'm willing to switch to ALSA, but a quick look says
it is the same there ).

Ideally I would want a second stereo /dev/dsp1, that would produce sound on the
rear speakers.

Thanks for any help,
David

Off topic.  Please switch to ALSA (OSS is deprecated) then ask this
question on the ALSA lists.

What "the ALSA list" is that? I have asked the same question on 
linux-sound several times and gotten no answer. If that list is dead it 
should go away!

Go to http://alsa-project.org/mailing-lists.php and pick one that
seems appropriate.

alsa-devel@alsa-project.org or alsa-user@alsa-project.org, I would
guess, as per the ALSA homepage.

Yes, it should.  linux-audio-user is active too.
