I have anew Yamaha RX-A2A receiver. Xfinity cable 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 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 is on with video and sound, but no control. Once the cable box is rebooted all control is returned.
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.
