No sound on ATI Radeon HDMI in Debian/Ubuntu

Debian based distribution users- Getting no sound through your ATI radeon hdmi?

I had this problem with the latest ubuntu/mint. Make sure xserver-xorg-video-ati package is installed properly and check sound settings output.

My only fix is to edit grub and add a kernel flag. Use your favourite editor and edit /etc/default/grub.

# sudo nano /etc/default/grub 

Tweak the 11th line.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"

Save an exit (ctrl + x for nano.) Reboot and try. Good luck.

You can also try installing the awful FGLRX package. I wouldn't bother though. Nasty stuff.
