Yes, there is some sort of incompatibility between Bose and Samsung that doesn't exist with other brand televisions.

I disconnect every evening HDMI cable, and I connect it again before switch on my tv. (Samsung 65HU8500)
This is the only way to have a correct behaviour of HDMI arc.
If the HDMI cable il always connected, by random (by night or day) my TV (and of course my Soundtoch) switchs on alone !!!!!
