1.всё делаем от root
Добавьте себя в группу audio:
gpasswd -a <user> audio
2.aptitude install binutils build-essential gawk gcc gstreamer0.10-plugins-bad libasound2-plugins libc6 libesd0 libtool libgtk2.0-0 libgtk2.0-dev libsdl1.2debian-all libsdl1.2debian-oss libsox-fmt-oss libwine-oss sed
3./etc/init.d/alsa-utils stop
4.aptitude remove alsa-base alsa-utils
5.dpkg-reconfigure linux-sound-base
6.modprobe snd-hda-intel
7.alsactl store
Не проверял,но думаю будет не лишним в пункт 6 добавить:
modprobe snd-pcm-oss
modprobe snd-hda-codec
modprobe snd-hwdep
modprobe snd-pcm-oss
modprobe snd-mixer-oss
modprobe snd-pcm
modprobe snd-seq-oss
modprobe snd-seq-midi
modprobe snd-rawmidi
modprobe snd-seq-midi-event
modprobe snd-seq snd-timer
modprobe snd-seq-device
modprobe snd-page-alloc

звук пошёл-донастраиваем в:система>параметры>звук(работает всё до reboot)

сразу после загрузки-modprobe snd-hda-intel
