HDMI audio was 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. There are reports on the Phoronix forums that this also fixes the fast video playback problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1160676 Title: [System Product Name, ATI RS690/780 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/1160676/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
