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/1091762 Title: [, ATI R6xx HDMI, Digital Out, HDMI] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1091762/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
