Audio/Video out of sync on Xfinity app installed on smart TV

I have a TV directly wired to the Xfinity modem and a computer on the home network.  I'm watching the Golf Channel.  On the TV the audio is widely lagging the video.  On the computer it is fine.

What [Edited: "Profanity"] wrong with your app?

mardukes Thanks for reaching out to us about the app audio lagging behind the video. I can understand how that would be rather annoying, and I'm happy to help get this fixed for you. Since the issue started have you tried any troubleshooting like uninstalling the app and reinstalling, as well as, a power cycle of the TV?

@XfinityEricB​ What seems to work at re-synchronizing is changing channel and changing back (about every 15 minutes.)  By my diagnosis, that is a problem with your app; TV has NO IDEA what channel is streaming -- can't imagine it buffering.

We would be happy to assist with troubleshooting the audio sync issues you are experiencing. Have you attempted to log out of the Xfinity Stream app on the TV, then uninstall and reinstall the app?

Why would I do that?  I will look into optimizing my TV, but if y'all can't supply & install legitimate updates...well, you are xfinity.  No one expects any better.

Often times uninstalling the Xfinity Stream app, and reinstalling it can resolve issues. Are you experiencing audio issues with any other channels?
