Public bug reported:
Hi
I had a lot of problems with this chipset. (ADI1981B)
On both (dapper+edgy) I have a strange problem : when the system is
installed, all seems to go ok ; even if I _reboot_ the computer, sound
goes ok. But if I _shutdown_ and then _restart_ my laptop the sound
looks very ugly : I have only a infernal whistle.
It's very strange that shutdown completely the system does it...
So I fix the problem adding : options snd-hda-intel index=0
single_cmd=1 model=laptop-eapd at the end of the file /etc/modprobe.d
/alsa-base
It works on dapper and edgy.
But when I installed Edgy, I had another problem : when I change the
volume with anything (keyboard shortcuts, software, ...) the sound is
cut ! I can't take it back even if I put the volume on his init value.
To fix this problem I use my old alsa-base (taken on dapper) and it
works well.
So, this was my old alsa-base (dapper) I actually use (You can see the
first fix at the end of the file) :

And this was on Edgy (without patch) :

So finally it works with the patched alsa-base of dapper. But I really
don't understand why a simple reboot doesn't do anything and a
shutdown+restart kill the driver :s
It's one of the most incomprehensible bug I ever seen... have you got an
explication ?
