Hi There, I have recently upgraded my entire setup, I bought the Samsung 82" MU7000, The Pioneer VSX932 and a set of Atmos speakers that stand on my Acoustic Energy Aesprit floor standing. System and TV is amazing. But, All of a sudden over the past few days the Amp/TV is not picking up the ARC, all my Sky,4K Blue Ray Player,Xbox, plugs into the AMP and then I have one HDMI 2.2 Lead going from ARC output of Amp to the SAMSUNG Box HDMI 4 (ARC) it works fine for Sky,Blueray, but when I go to watch Netflix or Amazon Prime, there is no sound and when I go into TV setiings the HOME THEATER AMP is not recognised, yet when I leave it all powered off over night, and then power on next day it picks it up and I can watch Netflix and amazon etc via the TV input of AMP, which uses the ARC.. I cannot understand why sometimes it recognises it and other times it doesn't, but when I power off and leave over night it then is fine.. I have attached some pics to show what I mean.. Pic 1 after unplug over night, on power up TV recognises AMP Pic 2 After a few hours TV Doesn't recognise AMP PIC 3 After longer period - Tv doesn't even pick up AMP at all and outputs to TV speakers when watching Net flix or Amazon prime APPs.
