Running slack 11.0 2.6.18.3.
I am so far that i have enabled my soundcard via howto on alsa-project.org but still i have some questions. here is an output of my lsmod:

when i run alsamixer i have four options to unmute

"1)Master 2)PCM 3)Mic Boots 4)Internal"

I hear the sound but i know there must be more options to unmute. With kernel 2.4.33.3 i had more options. And now when i want to watch movie there is a sound but when i want to listen music via
xmms it gives out a message that if my soundcard is configured properly and if i have correct plugin selected no other program is blocking the soundcard. Which modules should i insert into to have the soundcard up totally?

By default alsa mute some sound channel, it is informed after do alsaconf

To automatically unmute when boot, you can add the command-line based mixer called amixerinto a start-up script (e.g rc.local).

/usr/bin/amixer sset Master 100% on

to enable sound sharing, so you can play music using xmms and play a games (with sound too) try to install esd the sound daemon.

When you upgraded your kernel did you download the alsa source packages and recompile alsa? You need the driver, oss, libs. and utils packages. I had the same problem before I did this and now have full mixer controls.
