Hi,

My new Sonos ARC is connected to HDMI ARC TV input.

When Switching from music to TV I get the following message:

Connection Issue We’ve detected an issue with your HDMI connection. We’ll help you fix it.

After selecting Fix it I get the following message:

A device is interfering with the HDMI connection. Disconnect any other home theater products, the try again.

Only after I disconnect the cable box, running the Fix it works (until the same thing happens again)
