After building alsa-utils and alsa-driver, I ran alsaconf to configure my sound card and the information was stored in /etc/modprobe.conf:

   #
   # /etc/modprobe.conf: modprobe(8) configuration
   #
 
   # --- BEGIN: Generated by ALSACONF, do not edit. ---
   # --- ALSACONF version 1.0.14rc2 ---
   alias snd-card-0 snd-via82xx
   alias sound-slot-0 snd-via82xx
   # --- END: Generated by ALSACONF, do not edit. ---

lsmod shows:

   Module                  Size  Used by
   ac97_bus              2048  0
   snd_page_alloc    7816  0
   via_rhine             19208  0

I am assuming that the information in modprobe.conf is not loaded during startup. Please tell me how to load this file during startup. I've tried "modprobe -C /etc/modprobe.conf" but that doesn't seem to do anything.
