Hmmm,

You might want to look at this thread, about ALSA - because, from what I can tell, you have some modules that are using ALSA, and some that I think are NOT alsa -=- ALSA can not "compete" with another sound server, like OSS ( arts ), they will knock your ALSA right out of the water.

Also, ALSA is not a sound server that can be "clicked on" and "clicked off", like OSS within KDE Control Center - you boot up, disable all other sound servers, and run alsaconf to install, detect, configure, and boot with ALSA sound running... The Live CD is fine with a cheatcode, but after you hard drive install, you need to do this by the "Debian" book, so-to-speak...

Lastly, if you are going to use ALSA, you need to realize that it "initializes" the sound mixer as ALL MUTED. Run something like alsamixer to remove the MUTE, and adjust volume settings, then, when you have it the way you like, run alsactl store - this will save those settings. When you boot, if you have a hard drive install, add the following, at the bottom of your /etc/init.d/bootmisc.sh file: alsactl restore -=- and your volume settings will be returned after you boot.

Hope this helps,
