• Try a different HDMI cable (preferably high-quality and shielded)
• Check the audio output settings on the Rogers box—setting it to PCM may reduce issues

 

It sounds like a handshake failure on the HDMI link. Pioneer does not provide the version of HDMI on this receiver but judging from the video resolution and year of manufacture, it's probably 1.4. HDMI 1.4 is typically limited to HD (1080p) but had provisions for supporting up to 4K, without some of the newer 4K features later introduced in HDMI 2.0 and HDMI 2.1.

Assuming an analog connection is no longer possible, one solution might be to manually lower the resolution in the TV box menus to 720p, 1080i or 1080p. Another would be to replace the HDMI cable with a high speed cable that supports the wider bandwidth of 4K. Connecting the TV box directly to the TV and using the audio output from the TV (ARC or optical) to the AVR is suggested by Pioneer so it sounds like this may be a common issue with this receiver.

 

what kind of rogers cable box is it? is it the xfinity/ignite box? I never had xfinity, so not so familiar with the boxes, do they have toslink digital audio out puts?

No, HDMI only. Suggestions above apply. HDMI resolution change, or HDMI to TV, Optical from TV to AVR. (HDMI cable that comes with the Xfinity box should be adequate when combined with appropriate equipment.)

 

Another possibility might be to use an HDMI to component converter. There are some cheap generic brands on Amazon. There is no guarantee they will resolve the issues so check the return policy.

 

it could even be a problem with your receiver, do you have another device you can try to narrow down the problem?
