After upgrading to gutsy (in september) the snd-hda-driver started to
misbehave.
Now I have on up-to-date gutsy on Lenovo T60 and I have to always
modprobe (and modprobe -r) the driver at least twice before it works.
And the first modprobe takes more than 10 seconds. After a couple of
load/unload cycles the sound works.
