In the ALSA supported card list is not yours:

A saw that your card is audio enabled:

HDMI output support

   * Supports all display resolutions up to 1920x1080^2
   * Integrated HD audio controller with up to 2 channel 48 KHz stereo
     or multi-channel (7.1) AC3 enabling a plug-and-play cable-less
     audio solution^4

Try another sound output device and verify alsa-mixer ouput and digital 
output source in volumen control on your desktop (gnome-sound-properties).

Look at this:

Also consult ATI Wiki (Many card and some comment about HDMI Sound):

http://wiki.archlinux.org/index.php/ATI#HDMI_with_sound

Or try to tweak it with this:
