Hi,

I suggest following this procedure:

1. install Ubuntu 9.04 to replace Ubuntu 8.10

2. upgrade alsa to version v1.0.20 using this procedure:

http://monespaceperso.org/blog-en/2009/05/09/upgrade-alsa-1020-on-
ubuntu-jaunty-904/

3. Then copy-paste the following command into the Terminal in Ubuntu
9.04:

gksudo gedit /etc/modprobe.d/alsa-base.conf

4. and add these lines to the end of the file:

# Keep snd-pcsp from being loaded as first soundcard
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=auto

5. Then navigate to System>Preferences>Sound and change everything to
ALSA

6. reboot and retest sound using the speakers AND using headphones

Regards,

Mark
