HDMI audio on AMD/ATI GPUs 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 kernel boot options as described at https://help.ubuntu.com/community/Grub2/Troubleshooting#Editing_the_GRUB_2_Menu_During_Boot There was also a second bug in the original Ubuntu 13.04 "Raring Ringtail" release, which caused no HDMI audio. This was fixed in the 3.8.0-22.33 kernel update. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1176001 Title: [System Product Name, ATI R6xx HDMI, Digital Out, HDMI] Pulseaudio fails to detect card Status in “pulseaudio” package in Ubuntu: New Bug description: After upgrading to 13.04 the sound output option to HDMI has disappeared, it only shows me S/PDIF and Analog outputs. I've seen people saying that after upgrading kernel to some newer version everything is fine. I'll try to boot with the old kernel (from 12.10) and see what happens.
