Sorry for not replying sooner. I've been fiddling with the onboard intel8x0 chip but I want the cs46xx to work because the Hercules Game Theater XP has such a nice box with digital in/out, etc.

This is strange indeed. But at least the rear speakers are working fine. But when I try aplay -D pcm.surround41 started.wav there'e only sound from the front-right speaker. It's the same with pcm.surround5.1. If I try pcm.suround[4,5].0 I get "aplay: set_params:833: Channels count non available". > Something I've seen mentioned several times: > > $ cat /proc/asound/card0/ac97#0regs > > ... > > 0:7e = 5914 > That register is *supposed* to be some other value, for 4-channel sound > to work right, and I don't know what it means, if it is not. I have 592d but i have no idea what to do with this. > http://alsa.opensrc.org/index.php?page=cs46xx Funny, this page states: "Multichannel PCM has been integrated, and should work on all cs46xx based cards. Basically, the chip can be opened up to 31 times for output, without a daemon like ESD or artsd. (Is there an example somewhere for getting this to work with standard applications? e.g. XMMS?)" So it *should* work. But I think the suggestion Florian Schmidt makes about creating a surround pcm device in the .asoundrc file is a good starting point. I've tried a simple config but this doesn't work: pcm.cs46xx { type hw card 0 device 0 subdevice -1 } If you've got any pointers I like to hear them. When I find out how to solve this I'll post my solution. -- Powered by Debian GNU/Linux ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
