I decided to only use the ambient lights for my Chromecast.
But today i noticed that it again doesn't work properly.
When turning on my Raspberry everything works pretty well but after some seconds or minutes (seems to be random) the LEDs go off and on. When checking the live video, there's the same. The screen offen gets black and there's a delay.
After some time the Hyperion Control Website doesn't react and I have to reboot my Raspberry.
It's the same behavior when using my Raspberry 3 and 4. (I use the latest HyperBian version)
What could be the reason for this? A bad digital grabber?
