Is there a specific input i should use on the avr (cd,cbl, dvd,??)
Btw, there is no device connected to the tv,I just want to get the sound from netflix app and youtube.
I also had ARC issues with my $3,000 Denon AVR-X7200WA
using brand new high quality HDMI cables. Audio coming back from the TV through the HDMI worked initially, then became buggy, then would not work at all anymore, no matter what I did, including firmware update on the Denon. I gave up and ran an optical cable and it works great now. I will be curious to see if we hear more of this issue as time goes along.
As far as which input to use, my Denon has a TV Audio optical input for just this scenario. Works perfectly. For your situation it would not matter which input you use, as long as it is optical and you use that input when viewing content originating from the TV, such as Netflix, etc.
