Channels freezing and audio loss

Hello for almost 4 weeks now my local channels ABC NBC and CBS have been freezing and have audio dropouts.  It’s the Xfinity system that’s doing this because I can go OTA and the channels are perfect and the audio is flawless.

everyone I talk to in the neighborhood and my neighbor is a Comcast employee knows that this has been going on for weeks yet. Comcast refuses to fix the problem. They just drive around the neighborhood in new trucks.
