I have new Sky-Q, Sonos and Samsung TV. They are all working together but I'm not getting the sound I'm expecting.

Sonos: I have a Playbase, Sub & two Play:1s all paired together.
Samsung TV QE55Q80RAT.

The Sonos plays music as expected and when I'm logged in to my Netflix account via the TV, the sound is awesome, but when watching TV/Cinema/Netflix via Sky-Q, the sound is no better than the sound I got from my old TV with no Sonos. I can hear sound from the two Play:1s but I have to put my ear right against it and the same is with the sub.

Has anyone else experienced the same and if so, have you managed to fix it?

Many thanks for your tips and help in advance.
