Hve you tried to upgrade ALSA? Fedora Core 2 comes with a very outdated 
version of ALSA (alsa-1.0.3) so I'd strongly suggest you upgrade to at 
least ALSA 1.0.6 or 1.0.8. You should have something like this in your 
/etc/modoprobe.conf, and make sure you add the alsasound system service 
to the startup sequence:

======Modprobe======
Just make sure you comment out the lines that load the snd-intel8x0 
module in Fedora (I find this way, though more extense in the file, 
easier to maintain and debug).
# ALSA portion

alias char-major-116 snd
alias snd-card-1 snd-intel8x0

# module options should go here

# OSS/Free portion

alias char-major-14 soundcore

# card #0

alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

=====alsasound service=========

When the installation finishes....

At a console (as root, or 'su -') type:

# chkconfig --add alsasound
# service alsasound start

You now can adjust the sound levels with alsamixer.
