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 Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1097352 Title: [2842DDB, ATI R6xx HDMI, Digital Out, HDMI] Playback problem Status in “alsa-driver” package in Ubuntu: New Bug description: HDMI does not appear as an option in "Sound Settings... / Output / Play sound through" list.
