Fox Channel Lip Synch off with Soundbar

You are better off connecting the sound bar directly to the television.

Whenever I use my soundbar, Fox channel goes out of sync no matter what X1 Audio setting I choose for the HDMI output or the TV input. X1 restarts do not help. Other channels are fine. I’ve been troubleshooting this for weeks now...

find a 'talking head' channel and then use the TV's remote and locate the audio lip-sync menu. adjust the timing (+/-) until it is good. The adjustment affects only the current port.

This is an ongoing problem, yet resolved.  I have a 65" q9 series Samsung tv with a Sonos arc sound bar. Replaced HDMI cables with Auidoquest Cinnamon 4K/8k  on both connections, no difference.  Replaced x1 box with new 4K box, no difference. Better picture though. Have to set audio to stereo to get lip sync correct on CBS. Doesn't help on FOX?  All other channels are fine in expert mode. Same problem on my other TVs.

lip sync to audio is always an adjustment by the 'sink' (TV in this case). go to your TV's settings menu, audio, and find lip sync. tune to a live network channel where people are speaking and adjust for close match.

As suggested, adjusted the Fox station to a close lip sync, however that impacted the other channels that were not an issue previous to the adjustment. What does work is to set the Xfinity "audio" setting to "stereo" from "expert mode". lip sync issues are resolved. The audio is no loger inhanced and sound is not as good is the concession.

In addition to everything else mentioned below, I replaced the X1 box, didnt help. The only fix that works is to get out of "expert" mode and select stereo mode. I have two 4-8k Samsung TV's and a Samsung sound bar on one and a Sonos ARC sound bar on the other. Changed out HDMI cables to Quest cinimon 4k/8k cables, re-booted, adjusted sync - all to no avail. Switch to stereo and the lip sync issue resolved. Not the fix I wanted, full 5.1 dolby sound would be nice with lip sync issue corrected  Not sure who is working on a fix.

My Sony 5.1 Surround System (circa 2014) did require that I turned "on" the ARC function on the S.S. box.   Maybe that's the problem.

Newer Samsung TVs auto detect arc setting and connect sound bar via smart box. Verified both TV's via settings, see below.
