1. ONE CHAIN SETUP
SHIELD > INTEGRAL (Default/Custom EDID or AUTOMIX) > MARANTZ > SONY
This should give you 4K30 and HDMI full sound (you might need to set the SHIELD to best resolution instead of best frame rate, otherwise you will have 1080p60)
2. ONE CHAIN SETUP
SHIELD > INTEGRAL (Custom EDID 4K60 4:2:0, use GUI or IR to set it up) > SONY
+ 5.1 Optical out to Marantz
This should give you 4K60 4:2:0 video (PJ MAX) and 5.1 sound.
3. SPLIT CHAIN SETUP
SHIELD > INTEGRAL (Custom EDID 4K60 4:2:0, use GUI or IR to set it up) > TOP OUT SONY, BOT OUT MARANTZ.
This should give you 4K60 4:2:0 bit and MAY BE HDMI FULL SOUND. (need to be tested)
In your testing report, you said AVR display 444 RGB, which might means that Shield is on 1080p60, which might means that you haven't set the custom EDID manually yet to 4K60 4:2:0 or that you are using automix. (or it just means that it deals with 4K60 4:2:0 like if it was getting 4K30 4:4:4 since both share same frequency of 300MHz)
Please confirm or redo test with EDID set as mentioned above.
Since AVR is 4K30 4:4:4 max and if it accepts to decode HDMI sound at 4K60 4:2:0, i don't think you will be able to get it to output anything (like its menu) when it's decoding such signal.
However, this is something you can get fixed later by putting a scaler between Integral and AVR, so 4K60 4:2:0 goes to display, and secondary 4K60 4:2:0 goes to scaler for 1080p60 or whatever else your AVR accept, then you can get picture from AVR output.
To know what's coming in, you don't need to use AVR info, you can use GUI or APP for Integral or even PJ info or shield info.
