Does not recognise HDMI connection after a while

[hulster]

I have the same issue with a Samsung TV.  What I started doing is resetting the Dione via the web interface. It takes about a minute to reset. Curious if anyone has a better / different approach.

I ended up with buying a HDMI matrix switch with sound extractor. Using a QN95B Samsung.
But does not solve everything as the switch has not enough ports and there none with more then 3 input ports on the market.
So one  source is still connected on the TV.
The issues seems not to be only the Dione side. The Samsung seems still to have problems to passthrough LPCM properly.
After having such devices like Apple TV or my UHD Player connected via the switch the Dione detect LPCM properly.
But as  I need to use the source behind the TV I always have issue when switching between sources behind the switch and the one behind the TV.
