Problems setting up surround sound on a CMI8738 sound card
Hi everyone! Can anyone help me set up four channel and/or 5.1 surround sound in SuSE 8.2? I have a CMI8738 integrated sound card, and I was unable to set it to play on all 6/4 channels (I only get stereo sound). There are no varaibles for surround sound when I try to configure the sound card with Yast. I also tried modifying the /etc/modules.conf file to add 'options cmpci four_ch=1' line, then restarting ALSA, but nothing spectacular happened. On the SuSE site, my sound card appears to be fully supported! Thanks! Srdjan

Check out the documentation here: http://alsa.opensrc.org/index.php?page=cmipci I used to have one of these. My only problem with it was that it didn't do sample rate conversion on the digital out, but 99% of what I put through it was fine. You probably have to run 'alsamixer' to enable what you want. If the variable you want is boolean, you have to unmute it (volume won't do anything). If you want 5.1 you have to use the digital out (optical or coax SPDIF). This is true of any card. I highly recommend using the digital out and avoiding crappy sound systems such as the Creative ones as they use a proprietary digital interface (I had trouble at a computer store with someone who claimed that digital outputs were normally 1/4"...). I have a Yamaha system that works great, takes both optical and coax, and does dts. - -- James Oakley Engineering - SolutionInc Ltd. joakley@solutioninc.com http://www.solutioninc.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2-rc1-SuSE (GNU/Linux) iD8DBQE+5JvY+FOexA3koIgRAkzxAKCDor6/jH3JugI05XYpolNgsEpbVACfUSoD OEMkUyn+HaFGQAISKIxofoE= =z7bw -----END PGP SIGNATURE-----
