Comment 68 for bug 477226

Same bug on lenovo U350 on mandriva cooker kernel 2.6.33-desktop586-1mnb is solved by
stopping kmix then as normal user
pulseaudio -k
then as root
modprobe -rv snd-hda-intel ; modprobe -v snd-hda-intel model=dell-vostro

not tried the mic yet
Surely one can edit /etc/modprobe... for mandriva
Thanks for the thread
