For four months I have been running an identical system to that which you describe using a PS6, except the HDMI cable between the AV receiver and TV is only 6' long.
What is still proving difficult to get working the way I want is... achieving the same simple system power on/off control I had when using a Fire Stick. With the Fire Stick, it was easy to have the remote control power button turn the TV, Fire Stick and AV receiver on and off with one click. With the PS6, I am still struggling with this by juggling settings for HDMI-CEC and e.ARC and have not yet achieved the smooth ease of use I had with the Fire Stick. Other common remote control functions work satisfactorily on the PS6 remote control.
My problems may be due to the age of my Samsung TV and Yamaha AV receiver (13+ years but working perfectly). As instructed, I did connect the PS6 directly to my TV for the initial set-up but moved it over to the AV receiver as soon as that was done.
Of course everything else about the PS6 is wonderful and I don't regret the purchase one bit. I just miss the simplicity the Fire Stick remote control provided over the components in my home theatre system.
I should note that, while the all singing and all dancing PS6 BT-500 remote control and its 47 buttons works fine, all members of my family long for the simple 12 button Fire Stick remote control we originally cut the cord with.
If anyone reading this can tell me the answer to a related question, I (and possibly you) would appreciate the answer. Is there a down side to leaving the PS6 on (green indicator LED) 24 hours/day when the TV and AV receiver are off?
