Hi all:
I have a Vizio TV (model name: D65-F1; version: 2.70.33-1) and a Sonos Arc. The only other device in my ecosystem is my Comcast cable box.
Sometimes the audio cuts out, sometimes the picture cuts out, sometimes both cut out at the same time. Sometimes when these issues are occurring, the TV remote is unresponsive.
I’ve had the Arc for a year and didn’t have an issue until the last few weeks. I’m not sure what could have changed.
I have tried running just the TV and Sonos together (while streaming Netflix or Amazon Prime) and have no issues. I have tried just the TV and the cable box together and have no issues.
But put the three together and problems ensue. I have tried a CEC-less adapter at each end of the HDMI cable running between the cable box and the TV, and I’ve tried simultaneously having such an adapter at each end. I’ve toggled on the TV menu under the CEC option between “Enabled” and “Arc Only,” also to no avail.
I have also done factory resets on the TV and the Sonos (which I later read was unlikely to solve the issue). I’ve tried running just the TV and the Sonos together for a few hours under the assumption that this would “re-pair” the two, before re-introducing the cable box. But still nothing works.
My Sonos app confirms my system is up to date. Same with the Vizio.
Pretty much at a loss.
