Lenovo Y400 sound

[Carsten Aulbert]

What's the output of

lsmod|grep snd

?

For me, somehow the kernel module snd_intel8x0 was not loaded
automatically. Since I'm not 100% certain this module is the right one
for you (though I suspect it might be), try to load it, if not yet loaded:

sudo modprobe snd_intel8x0

If sound is working after this, add this module to /etc/modules and
everything should be set.
