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 auto

or

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

The default setting is auto.

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
