Mark Rijckenberg proposed the following answer:
Hi,

Please first try this procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (copy/paste each command into the
Terminal and then hit <enter>)

sudo aptitude update
sudo aptitude install gnome-alsamixer asoundconf-gtk

Step 3: copy-paste the following command into the Terminal:

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

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=3stack
options snd-hda-intel enable_msi=1

If that model option does not help, try one of these alternatives:

 AD1988/AD1988B/AD1989A/AD1989B
   6stack 6-jack
   6stack-dig ditto with SPDIF
   3stack 3-jack
   3stack-dig ditto with SPDIF
   laptop 3-jack with hp-jack automute
   laptop-dig ditto with SPDIF
   auto auto-config reading BIOS (default)

Step 4: Then navigate to System>Preferences>Sound and change everything
to HDA ATI HDMI (ALSA)

Step 5; reboot and retest sound

Step 6: Experiment with the audio settings in gnome-alsamixer and
asoundconf-gtk until you get sound (hopefully). Both tools can be
launched through the Terminal


If the previous procedure did not work, please try these 3 alternative procedures:

http://vaioubuntu.wordpress.com/2009/07/08/hdmi-sound-output-switcher-for-pulseaudio/

Make sure to also try this:

You need to enable IEC958 switch for HDA ATI HDMI in volume control in gnome-alsamixer. 
Then select HDA ATI HDMI (ALSA) in sound preferences where you can test the sound.

Regards,

Mark
