Sky TV won't play right audio

[NBolton · Accepted solution]

I have returned having solved the issue. 

I was able to further define the issue in that on the Sony Bravia TV there is an Arc hdmi (3) next to 2, then 1&4 in the back.

I found 1&4 wouldn't play right, but 2 would. After trying all sorts I eventually factory reset the TV and now all hdmi ports are outputting both right and left.

For those searching; root cause was something to do with the Sony Bravia TV.

The solution was to factory reset the TV.

Thanks for helping me. It was appreciated.
