Audio delay/sync issue on TV after October 2016 update

After the October 2016 update, I have a delay between the video displaying and the accompanying audio.

The delay varies, sometimes it is synced up correctly, other times it's up to 3 seconds behind.

Exceptionally frustrating.

I'll be watching a show and the audio will be synced correctly, fast forward and when play resumes the audio is now out of sync.

Hardware:

Fiber Uverse DVR

HDMI connection

Sharp TV

Direct HDMI connection from DVR to TV
