Public bug reported: This is a terrible bug:
I have my speakers attached to my monitor, so sound is played via Displayport audio. No problem at all. BUT: My monitor goes to sleep after 10 minutes or so. When it's woken up again, no sound whatsoever is played back any more. Going to audio settings still shows Displayport/HDMI audio selected. When I switch my monitor OFF and ON again, sound is back.
