** Description changed:
+ 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_LINUX_DEFAULT="quiet splash"
+
+ to this line
+
+ GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"
+
+ 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.
