[linux-audio-dev] Multichannel sound ?

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 ---------------------------------------------------------------- Varno.
