If I run alsamixer and make a change, that change will sit there for
seconds, minutes... probably hours or days. It's only after I try to
play a sound that it re-sets itself.

Here's what alsa gave me:
[root@timdl1 root]# cat /etc/modules.conf
alias eth0 8139too
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF verion 1.0.3rc2 ---
alias char-major-116 snd
alias char-major-14 soundcore
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
alias snd-card-0 snd-intel8x0
# --- END: Generated by ALSACONF, do not edit. ---
alias sound-slot-0 snd-intel8x0
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L
>/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S
>/dev/null 2>&1 || :
Can I have more than one post-install and pre-remove?
