New Receiver with Xfinity

I have a new Yamaha RX-A2A Receiver. Xfinity X1 cable plugged into in HDMI 1. Fire TV 4k stick in HDMI 2. Chromecast in HDMI 3.

Connected to 65" LG OLED TV.

Everything works until I switch from either the Fire TV stick or Chromecast back to the HDMI 1 - Xfinity cable box. What happens is that all control of the cable box is lost (no channel change, no guide, etc) unless I reboot the cable box. The last channel previously on will come on with video and sound when I switch back to HDMI 1, but no control. Once the cable box is rebooted all control is returned, until I switch HDMI inputs again. This happens about 80% of the time. The other 20% of the time, when switching to HDMI 1, everything works fine.

Also, one thing I noticed is that when everything is working, the receiver shows "Xfinity" on the screen. When it is not working it says "STB box".

Anyone have any ideas? It's a real pain having to reboot since Xfinity box takes about 5+ minutes to complete.

Thanks.

Thank you for reaching out to us @sbudaj! Just to confirm, is the HDMI from the Xfinity cable box connected to the Yamaha RX-A2A and then the Yamaha RX-A2A sends the signal to your TV?

If so, the HDMI-CEC features may be causing this issue. Are you able to disable HDMI-CEC on your cable box? To disable this feature please follow these steps:

Click the "Xfinity" button
Go to "Settings"
"Device Settings"
"Power Preferences"
Scroll down to HDMI Device Control (HDMI-CEC)
Change "On" to "Off"

Additionally, we may need to disable the power saver settings on the cable box. These settings can be accessed by:

Clicking the "Xfinity" button
Going to "Settings"
"Device Settings"
"Power Preferences"
Scrolling down to "Power Saver"
Changing "On" to "Off"

Thanks for the reply. Yes, the Xfinity HDMI cable is plugged into the Yamaha receiver, then the receiver HDMI output is plugged into the TV.

I changed the HDMI-CEC to off. Power saver was already off. I will try this a few times and report back if this works.
