--- Comment #12 from Metz <metzelket...@gmail.com> ---
I can confirm this behavior. When my 3 displays go to standby its starts with a
disconnect / connect loop. it is relatively inconsistent when the problem gets
triggered. but i just tested with a 60 second timeout and got this:

So my suspicion was that pulseaudio detects the HDMI audio device of one of my
3 dispalys over and over again for some reason. so i disabled only this display
and at first nothing happened. but after powering it back up i got the
disconnect/connect sound again and this:
