I’ve changed my living room from an Arc, Sub and surrounds to an Amp, third party front speakers and Sonos surrounds. 

I’m really happy with the sound and it’s honestly transformational for listening to music. The front speakers have enough bass for movies rid etc. 

My only quibble is that if I’ve been listening to some music with a higher dynamic range on the Amp, and then switch the TV on, the volume is too loud. 

With the line in you can set up the Amp to autoplay with a default volume but you cannot seem to set this for TV via HDMI eARC. 

Is there a way to do this?
