GOOD news!! I found a workaround that could be useful for others with the same problem as well as for finding the cause/solution.
I noticed that I do get audio over hdmi when I close the laptop with the hdmi cable connected. It then goes to sleep. When I open it the audio over hdmi magically works! Is there any details I can post for the ubuntu devs so they can find out what causes this bizarre issue? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1264665 Title: [W65_67SZ, Intel Haswell HDMI, Digital Out, HDMI] Playback problem, pavucontrol shows hdmi signal but no sound on tv To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1264665/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
