HDMI audio was disabled by the upstream kernel developers as it causes blank screens on a lot of systems.

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/897008 Title: HDMI: no sound, video too fast To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/897008/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
