How do I stop receiver input auto-switching?

Hey all, I've recently upgraded my HT gear to 4K and this is what I have:

Display: LG OLED65E6P
Receiver: Yamaha RX-A760
Blu-ray Player: Panasonic DMP-UB900
TV Cable Box: Cisco Explorer 9800 PVR
Others: Apple TV 4 32GB, Playstation 4 launch edition, Playstation 3 launch edition.

All devices are connected to the Receiver via HDMI, with one HDMI output connected to the ARC HDMI input on the Display. (HDMI input 2).

I needed ARC for viewing Netflix on my TV in 4K with Dolby Vision.

My problem is when I watch my PVR, the receiver switches the audio to AV1 as that is the input I have designated for the ARC audio. I need the Simplink HDMI device control (CEC) to be on for both the Receiver and the TV in order to hear Netflix on my Display. That's fine and easy to do... however my Receiver loves to switch on all other devices first, when I switch over to the Explorer 9800. I've turned off the CEC controls on all other devices including the Playstations, Apple TV, and Blu-ray player (all of which the receiver turns on by itself). So now, none of those devices turn on automatically and instead, my Receiver defaults back to AV1 instead of HDMI 2 where I have my Explorer 9800 plugged into. This happens whenever I switch from the Netflix app on my display to the Explorer, and when I turn on my TV in the morning to watch the news, I have to wait for it all to turn on, sound will briefly come from the Explorer until seconds later when the Receiver switches over to AV1 input, forcing me to hit the HDMI 2 input on the remote to get the sound back again.

Simply put, my Receiver does not seem to recognize that it is receiving sound signals from my Explorer PVR and won't stay on that input.

All this of course corrects itself when I turn off the CEC functions, but then I have to turn it back on each time for Netflix.

Is there a way to force the receiver to default to HDMI 2 instead of AV1?

Hope this all makes sense!

Probably the simplest thing to do is plug the PVR into your TV's HDMI and route the audio through ARC to your receiver.

You can change video inputs and audio input assignments with your receiver, but that might only be of use if you're inputting digital optical cables from your PVR.

But I'd plug the PVR into your TV directly and output the audio through ARC when you want surround.

I have not yet seen CEC work correctly when needed for one input as from what I've seen, it screws up functions with other components in the system. that's just been my experience. it's still not at a "it just works" yet stage. perhaps, one day it will work perfectly as intended.

I'm sure for some it does work without exception, this has just been my personal experience with it.

Thanks for the tips.

I could try plugging the PVR directly into the TV, that should work since it doesn't put out anything better than Dolby Digital 5.1 sound anyway. That will work through ARC and when the receiver defaults to AV1, I'll have sound!

Yep, CEC still doesn't work as I'd like it to you're right. It's not the smartest thing on these smart tvs and in smart homes eh? lol
