Have the same problem on Ubuntu 12.04 with Unity. Sometimes when I plug in my HDMI TV to my Dell laptop the audio will not work, the HDMI audio device is not present in Unity, Pulse says "available: no". This could be connected to hibernation, but I'm not 100% sure. A reboot always solves the problem, but that is a very bad option for me.
Just for anyone who wants this solved quickly in a simple way: Write a script that uses "xrandr" to check whether the TV is connected. Then have it check "pacmd list-cards" under ports whether the HDMI output is "available: yes". If the TV monitor is detected with xrandr, but the HDMI output (sound) is not available, have it run "killall pulseaudio". I have this in a loop, causes very little resources, but is a (admittedly dirty) pragmatic fix for the problem. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/974963 Title: [soundnua]: hdmi audio missing in sound settings Status in “alsa-driver” package in Ubuntu: Incomplete Status in “gnome-control-center” package in Ubuntu: Invalid Bug description: When using sound settings, under unity, the option hdmi-audio is missing, while under gnome-panel it is available and works fine.
