Xfinity audio remains when TV is switched to other streaming sources

System: Xfinity account feeding wireless set-top DVR (excellent WiFi signal strength). HDMI from there to sat/cable input on Denon AVR-S570BT, out from AVR to HDMI 4 (eARC) on TCL R635 Roku TV. In addition to Xfinity TV fare, I stream from Netflix and Amazon Prime (subscribed and billed THROUGH Xfinity and Apple TV (subscribed directly) from Apple. I also access content from a PleX server on my desktop PC. 

All of these played well together until very recently: while on Xfinity I could switch to Netflix or Prime or Apple by voice command to the Xfinity remote OR by using the Roku remote to bring up the TV's home screen and select N/P/A. I used only the Roku TV switch for PleX, as Xfinity does not allow choice of a server. In all cases, I got the appropriate audio as well as video.

Starting about ten days ago, with no hardware or setting changes, if I switch from Xfinity to N/P/A by voice command to the Xfinity remote, all is well. But if I switch using the Roku TV interface, I get the video I want but BUT STILL GET THE XFINITY AUDIO CHANNEL non-stop along with video from the other four streaming sources. I have unplugged shut down and restarted the Xfinity gateway, the DVR, and the TV; factory reset the Denon; tried other HDMI cables, all with no luck.

The problem disappears if I run HDMI straight from the DVR to HDMI 4 (eARC), but then I lose the 5.1 sound system and have only the TV's speakers. More to the point, the DVR -> AVR -> smart TV path worked perfectly for a long time and stopped working for no reason I can see. 

Any ideas?

Are you switching the Denon to the TV Audio input when playing a streaming app on the TV?  That's how it knows where to find the sound.

@XfinityThomasA  This doesn't look like an Xfinity issue.   He gets the correct video and audio using the Xfinity apps.  But, when using the apps on the TV, he gets audio on his AVR from Xfinity.  Seems pretty clear that his receiver is on the wrong input.
