HDMI audio on the ATI Radeon 5000 series requires a 3.3 or later kernel. Ubuntu 12.10 "Quantal Quetzal" has a 3.5-based kernel.
Also, on ATI Radeon cards/chips, HDMI audio has been disabled 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. See https://help.ubuntu.com/community/Grub2/Troubleshooting#Editing_the_GRUB_2_Menu_During_Boot for details on how to do this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/731138 Title: cannot test sound.
