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.
