Why does my Xfinity Flex 4K XiOne-SC(B) play two tones roughly every 30 minutes to an hour?

TV is off, but flex is plugged in and connected via ethernet and HDMI. Randomly, throughout the day, it will play two tones (lower, then higher pitch). Why is it doing this? I can only make it stop if I unplug the power to it.

Hello tnguy,

Have you attempted to swap your HDMI cable? It seems like there might be some cable issues in the signal chain.
