When I connect the laptop to my tv-set I have video (not always, separate topic!) and audio. But when I switch the input on the tv to something else (for example to see if a certain event has started on tv) and I switch back then my sound is gone!! And it stays gone until I switch off the laptop and switch it on again. Even rebooting won't help! I really have to bring it down completely (which is a pain because it takes ages to boot).

 

When I open the sound-window I can see the HDMI-output playing (the green bars to the right). Pulling out the hdmi-cable doesn't return the sound to the laptop-speakers either. Only turning it off and on will work.

 

Anybody else got the same problem?
