Bug Description
Since kernel 3.0, upstream has disabled audio output for all ATI cards in the Radeon driver by default.
=== Workaround 1 ===
Edit /etc/default/grub and change this line:
GRUB_CMDLINE_
to this line
GRUB_CMDLINE_
Now run "sudo update-grub", then reboot your computer.
=== Or workaround 2 ===
Install the proprietary Catalyst driver.
===
There's no sound at all and videos playback in fast forward when outputting through the HDMI controller. This is a regression since it worked well in previous releases.

Hi Melvin,
nothing looks bad on the audio driver side, so it should probably be reassigned to xserver- xorg-video- radeon (I'm trying to do just that, but Launchpad gets an error when I try :-( ).
Is this a problem both on clean boots as well as returning from suspend/resume?
