Public bug reported:

Binary package hint: xorg

I'm using Ubuntu 10.10, fully updated from the regular repositories.

I connect my laptop to an HDTV through HDMI, configuring it through
Preferences -> Monitors. I switch sound output to HDMI in System ->
Preferences -> Sound -> Output. This works flawlessly as long as I
somehow use my laptop monitor, meaning that I either mirror the screens
or use an extended desktop. If I turn off the laptop monitor there is no
sound output through the HDMI; turning back on the laptop monitor
restores sound output to the TV. Switching back to the regular output
device works as expected.
