I also use the open-source Radeon driver with no hdmi-audio, but in Settings / Sound / Output the "HDMI / Displayport builtin audio" is listed. Does this contradict the statement that hdmi audio output is disabled?
I tried booting without and with the suggested option "radeon.audio=1", with no difference. I also used the "test" option in the Settings / Sound configuration screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/912866 Title: No more audio in 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/912866/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
