As Luke said HDMI audio on Radeon hardware has been disabled by default by the upstream kernel developers, as it causes blank screens on a lot of systems. You can re-enable HDMI audio by adding "radeon.audio=1" to your GRUB boot options. There are reports here in Launchpad and on Phoronix that this also fixes the fast video playback problem.
