The upstream 3.13 kernel is currently under development. The
radeon.audio=1 kernel boot option will no longer be necessary with this
kernel. Instead, HDMI audio on ATI/AMD Radeon cards can be enabled and
disabled on the fly by typing the following in a terminal window:

xrandr --output HDMI-0 --set audio on

or

xrandr --output HDMI-0 --set audio off

If your HDMI port is numbered differently (type "xrandr" to check) - you
might need to change HDMI-0 in the above command to HDMI-1 or HDMI-2.

The 3.13-rc2 kernel is currently available at http://kernel.ubuntu.com
/~kernel-ppa/mainline/ and instructions on how to install and uninstall
it are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds

Title:
  1002:9715 HDMI: no sound

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Since the 11.10 upgrade, when Digital stereo (HDMI) is chosen as audio
  ouptut (audio settings, Output tab), no sound comes, and video
  playback is very fast, as if there's no pause between frames.

  There are 2 entries in the output tab. One is RS880 Audio Device
  [Radeon HD 4200] Digital Stereo [HDMI], the other is Internal audio
  stereo analog.

  No problems when the other output is selected. Even video oplayback is
  OK.

  Some search results say that this happen when the HDMI monoitor is
  disconnected and HDMI is selected. In this case, the monitor is
  connected with HDMI and video has no problem. Also. the exact same
  configuration did not have this problem in 11.04

  WORKAROUND: adding "radeon.audio=1" to your GRUB boot options.
