Posting this here because it is vexing me and I hope someone can help. I just picked up a Vizio P659-G1 and hooked it up. Because my AVR is the Denon 5200 and it isn't HDCP 2.2 compatible, I'm running HDMI 1 of my UBK90 to the Vizio and HDMI 2 to the Denon. I do use the Denon for my regular Blu-ray player (Oppo BDP-103) and my Uverse box, so it is hooked up to the Vizio as well, and I'm running CEC for ARC only so I can get audio from the Vizio's internal apps.
When I change to the HDMI port for the UBK90 and change my AVR to the right input, I get picture... but no audio. When I change my Vizio to the HDMI port for the AVR, I get the audio from the UBK90 but no picture. I've noticed that when I have picture from the LG on the screen but no audio from the AVR, the system info on the Vizio shows the TV receiving stereo... then nothing... then stereo... over and over again, randomly.
I've tried turning CEC off, turning ARC off, etc. and nothing fixes it. Disconnecting the AVR from the TV is the only way to get both audio and video from the UBK90, which is odd. Anyone know a way to work around this?
