I use a compaq Presario CQ 40 note book.
while I was on 8.10, I experienced illegibel sound output.... The
welcome drum roll was longer than usual and unclear. I resolved this by
just cd to /etc/modprobe.d/alsa-base as root and adding:
options snd-hda-intel model=3stack-dig
options snd-hda-intel enable_msi=1
options snd-hda-intel single_cmd=1
On rebooting, the sound became perfectly alright.
When I upgraded to 9.04, I noticed there was no sound at all. I tried
the same thing as above but it didn't work.
Hoever, I keep getting some garbled sound in the head phone, even when
no sound is playing.
The lspci -v -v out put is as under. Can some one help me with this?

Subject: [Bug 354398] Re: Acer Aspire 8920G has inaudible audio by default
This bug-report seems to have been hi-jacked by a couple of people with
individual problems about this. It seems that the original question has
become slightly buried by these and doubtless we can expect a lot more
people to jump on this as it seems likely to affect a lot of people.
It is, of course, quite legitimate for people to seek help about this
issue here - certainly it's better than separate questions and separate
bug-reports springing up all over the place. I just hope people can
find a work-around!
Good luck and regards from
Tom :)

Bug description:
Binary package hint: alsa-base
The chipset is in an Acer Aspire 8920G laptop. But please note that this
appears to be a generic chipset with a lot of users experiencing the
same problems (and possibly the same solution??)
This bug applies to Ubuntu 8.04 (final), 8.10 (final) and 9.04 (beta
release). In each case all available updates were applied to the Ubuntu
OS release.
I am currently using ALSA 1.0.18 (fully updated from Jaunty
repositories).
Output of lspci -v -v is attached.
I tried following the Ubuntu audio faqs (e.g. switching to Pulse Audio)
to no effect...
Basically I cannot switch on the digital optical SPDIF output or get any
analogue sound output!!
THIS IS A SERIOUS PROBLEM AS JAUNTY IS STILL BROKEN AND SO MANY PEOPLE
ARE AFFECTED!!
NB I know the "snd-hda-intel" kernel driver module supports the audio
device... It still needs a simple work around however and doesn't work
out of the box!!
