Actually it is video card related. You need to have one that supports
HDMI pass through.

The standard 'Radeon' driver doesn't support HDMI sound pass through.
The get that you must install the Radeon HD video driver and configure
it for Audio support manually - since it doesn't automatically detect
HDMI sound capable devices yet.

apt-get install xserver-xorg-video-radeonhd

Then configure xorg.conf so that it contains the following settings:

Section "Device"
        Identifier      "ATI Radeon HD 3200/RS780"
        Driver          "radeonhd"
        Option          "DRI" "On"
        Option          "Audio" "On"
        Option          "HDMI"  "all"
EndSection

Section "DRI"
        Mode 0666
EndSection

(Change the Identifier as required so that it ties in with the rest of
the configuration).
