Power Station in Home Theater System

[cyrowth]

Considering a PS6 purchase, but saw several threads online that raised issues with it being plugged into an A/V receiver vs directly into TV  (then using e.arc).  I have a remote electronics cabinet with a 25' 8K HDMI cable running from my receiver to my LG OLED TV.   All current video and audio devices (including 2 Android TV/Google TV boxes) are plugged into the receiver with HDMI-CEC enabled on all devices, and everything seems to work just fine. 

So, a new Power Station 6 would  be connected to internet via ethernet and by HDMI to one of the inputs on the receiver -- with the TV connected to the TV OUT HDMI port on the receiver.

The Buzz PS6 setup says “The PS6 MUST be connected directly to the TV with the included HDMI cable”

One online post claims that this Buzz PS6 "requirement" to connect directly to the TV is only mandatory for initial setup.  However, another user with the PS6 says that he had issues setting up his PS6 by connecting directly to his TV and then moving it into his Home Theater system (setup like my A/V receiver centric system).  He relayed some issues after moving input from TV to receiver (i.e. apps not playing properly, etc.).  

Is this really a HARD requirement to plug PS6 directly into TV ?   What would be the major concern if I plugged a PS6 into my A/V receiver as with my current Formuler Z11 Pro Max and Onn4K Plus devices ???  

Hard for me to believe that any high-quality Android/Google TV box can’t be plugged into an A/V receiver and from there into the TV.  With the expense of the PS6, I don't want any surprises after purchasing.
