Hi all

I’ve recently set up a new amp with existing in ceiling speakers and it works great. I’ve also connected the amp to a 2018 LG OLED via hdmi arc which pushes the sound out through the in ceiling speakers - also great.

The issue I have it switching off the amp to return to playing the tv via a sky soundbox (also conducted to the tv via hdmi). This seems impossible to do, other than by physically unplugging the amp from the arc hdmi port on the tv. 
 

I only occasionally play the tv through the in ceiling speakers but it would be nice to find a slicker solution than the above workaround.

I have seen similar posts without a solution from a couple of years ago so I thought perhaps someone might now have found a fix.

cheers.
