Never have that problem here with SB Audigy ES card. Have you tried to modprobe your sound modules when this issue arrises? I believe for your sound you would issue as root
Code:
modprobe snd-intel8x0;modprobe snd-pcm-oss;modprobe snd-mixer-oss;modprobe snd-seq-oss
That is the only module for Intel soundcards, I believe. You can issue "/sbin/lspci" as a normal user and get the Multimedia audio controller output and check at the
ALSA site for the correct modules if that's not it.
