I have not had that problem (yet). Everything is in my modprobe.conf:
# Note: for use under 2.4, changes must also be made to modules.conf:
=========================
[...]
# sound stuff, subject to heavy mods in future
# For Alsa
# 1st, make the SB Live / SB Audigy 2 the default
alias snd-card-0 snd-emu10k1
# 2nd, and then skype can use /dev/dsp1
alias snd-card-1 snd-intel8x0
# For Alsa's Oss emulation?
alias snd-slot-0 snd-card-0
alias snd-slot-1 snd-card-1
# Alsa's Oss emulation
# for emu10k1/SBLive Value/Audigy 2 Value stuff
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
# for nforce2's ac97 chip
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-1 snd-seq-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-8 snd-seq-oss
alias sound-service-1-12 snd-pcm-oss
# But, whats this?
alias char-major-116-* snd
alias char-major-14-* sound
install synth0 /bin/true
# end of sound
=============
Maybe theres some clues in that?
