I suspect that this chipset isnt always being detected correctly by the kernel. I have completely gotten rid of these problems on 1 machine thats using this module.. vastly improved another and got a 3rd working perfectly from no RO sound at all with playing with the model= parameter of the snd-hda-intel module.

In the case of my laptop the best get was " options snd-hda-intel model=lenovo-sky "

Other may want to look into other options or perhaps try one of these:

/etc/modprode.d/hda-intel.conf

Code:

# Only use 1
#options snd-hda-intel model=3stack 
options snd-hda-intel model=3stack-6ch 
#options snd-hda-intel model=3stack-6ch-intel

Or you can use this script to gather info about your soundcard and find a models= option that better suits your actual hardware.

~/alsa-models.sh

Code:

#!/bin/bash

## Changed this if needed
EDITOR=gedit

mkdir ~/tmp-alsa-info
cd ~/tmp-alsa-info
wget -q http://www.alsa-project.org/alsa-info.sh -O ./alsa-info.sh
chmod +x ./alsa-info.sh
./alsa-info.sh --no-upload --output ./alsa-info.txt
cat  /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz  |gunzip >./HD-Audio-Models.txt
$EDITOR ./alsa-info.txt ./HD-Audio-Models.txt
cd ~
sleep 2
rm -rfd ~/tmp-alsa-info

chmod +x ~/alsa-models.sh
~/alsa-models.sh

This will gather the info and open the needed documents.

yep same here. Three people from my clan have no sound at all. By me the sound is nasty and at the end the game freezes. We all use Ubuntu 9.10. 64-bit.

According to this they forced people to use broken PulseAudio. Nice.
My advice for those that haven't yet upgraded is not to do so. God, compared to Ubuntu guys, NGD people are real angels. Additionaly i have WiFi issues, and i guess i'll switch back to Debian on my desktop ASAP.

Edit: Of course i have those audio problems myself.

On Arch Linux 64 bit I have no problem with sound, so it seems the problems do come from Ubuntu 9.10, and because of that PulseAudio.

I think it's more the version of the packages installed because i have problem on a gentoo too.

Ok people what I did was this:

In the terminal:

sudo gedit /etc/openal/alsoft.conf

change the divice line form Alasa backend stuff to this:

## ALSA backend stuff
##
[alsa]

## device:
# Sets the device name for the default playback device.
device = alsa

remember to un coment it.

Hope this helps.

I think with this setup your sound card will be busy for other sound program using pulseaudio, except if your other program are configured to use alsa too.

yup me too ;P

I've found that the sound issue is not only on the 64 bit. From a fresh install on 32 still get the issue, I simply updated Alsa to the latest, though i know its not an issue with 1.1.20, it's certainly an issue.

of course, I was hoping not to have to use a processor workaround for the high CPU usage...but that's a Regnum issue.

a simply ALSA update works, for those on Ubuntu, theres an upgrade script to the latest alsa on the forum.
