HDMI Audio is disabled by default on kernel 3.0+ due to a black screen on some monitors.
To get audio working again go to:
Then change the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"
Type on the terminal:
Reboot and your HDMI sound will work again.
Can't edit the file. It's locked in the GUI. How do I get permission?
