55aj90 connected with sky q and bdw7200 surround sound

[Dairbear]

I received my 55a90j yesterday and am having difficulty with the connections.

On my previous Sony I had my sky q connected to the TV with hdmi, connected to my sony bdw7200 surround sound with an optical and then the bdw7200 was connected to the TV with an hdmi to the arc .

This is having problems on the 55a90j

I wondered if connecting the sky q to the bdw7200 with hdmi and then connecting the bdw7200 to the 55a90j with the hdmi arc was a better connection

Any help would be appreciated

Checked youview again via TV and 7200 and weirdly it's now ok, I'm beginning to wonder if the factory reset of the 7200 yesterday and the removal of the optical has fixed it. However the 7200 before the arrival of the new TV had an 4k firestick in the back of it and it regularly went wonky , needing a bluray to play to make it comeback to normal. Now that is out and in the old TV  and maybe the factory reset and only the TV hdmi connection to worry about, it might behave itself from now on.  If it ever gives up the ghost, the plan is to get an av receiver to work with the surround speakers.
