Hey Verizon,
I have a new Fios TV installation and there is an audio delay issue from the STB when Dolby Digital 5.1 (surround) Audio Format is selected.
Switching to LPCM (stereo) Audio Format fixing the issue but I did not sign for the TV service to hear the channels in stereo on my home theater setup and definitely not to watch them with annoying lip sync issues.
The delay happens in both HDMI and OPTICAL outputs from the STB.
Just to clarify, the audio stream is being sent with a delay and lagging the video stream, which means that the "Audio Delay" function that is common in the various devices can't help.
Please provide a solution and by solution I mean something serious and not the: "replug the power", "reconnect the cables", "try different cables", etc.

He tried optical from Fios box to TV. Try optical from TV to soundbar. Also I read in posts on Samsung forums that there is a built in 30ms delay baked into the Samsung TVs. The only way to change it is through the service menu. Don't know if it will help, but there are several posts on Samsungs forums about it and how to change it.
I spent quite a bit of time reading this thread. It seems to describe the issues I'm seeing including the lip sync, changing to PCM working, and using passthrough working. It also describes the issue with the sound bar not turning on automatically when using passthrough.
The solution for changing the HDMI delay level didn't really make much of a difference for me.
Also, multiple people on that thread indicated that using optical to connect TV to the sound bar didn't make any difference.

Good to see someone's actually read about the problem with the Samsung TVs recent firmware updates. I'm just trying to give every possible option for people to try in case any of them work. Also good to note that LPCM isn't necessarily stereo only but can be multichannel. Its system dependent, not sure if the 4100 sends out 2.0 or 5.1 via LPCM. Trying optical can sometimes reduce audio delays that occur with ARC implementation, but sometimes it creates it's own delay. Its unfortunately a problem with the manufacturers not closely following the established standards for AV transmission and we are really lucky when it all works.
I just got a Samsung 7100 65 inch tv and the audio and video are out of sync. The lips are never in sync with these audio. What's going on here? I just also got the fios one box.
How can isolve this?

Are the people speaking before their lips move, or after? Do you use a soundbar or AV Receiver, or is the Fios box going directly into the TV?
Fios box goes directly to the TV. I have no soundbar. I'm thinking the sound is delayed slightly after the picture. Someone slams down something ad a split second later I hear the sound.
So annoying to watch the news. All the lips are off.
I saw something about going into a diagnostic mode (Power, OK, OK) and set the Fios One box to "Pass Through" this seems to have matched up the video to the sound... Not sure if it was appropriate for me to do so...
Is this a Samsung thing, or... ???
You can certainly go into the service menu and change options, just be careful what you change. I usually take a photo of the BEFORE screen then make my changes so I can go back if necessary. Hope the pass-through works for you. It is beginning to look like a dis-proportionate number of people with this issue have Samsung TVs. I read on their forum Samsung programs in a 30ms delay on the audio as standard. If you check, there are posts that tell how to change that in the TVs service menu.
Ifit was Samsung's fault why would passthrough solve it? It should still have a 30ms delay regardless of being pass through or Dolby. Seems to me processing the audio to Dolby in the fios box messed up the audio sync... passthrough, where the signal is unaltered keeps the audio sync perfect... If it wasSamsung's fault the delay would be there even after changing the fios box to passthrough as well.
The 30ms also would affect watching from streaming apps, which are unaffected based on what I'm seeing and everybody else is reporting. I've also experienced significantly different lag on different channels, which would indicate that it's not a fixed delay but rather some kind of bug in processing.
clem53 - can you post links regarding: "The only way to change it is through the service menu. Don't know if it will help, but there are several posts on Samsungs forums about it and how to change it."
I tried to search for it but couldn't find anything.
Pretty sure if you check the links I posted earlier, at least one of them tells how to access the service menu.
Saw this on Samsung forum. Might be worth a try.
FYI For some that are having issues as well:
No matter what I did I couldn't fix it with the audio setting so I took a chance and figured maybe the problem was with the frame rate, so I went to Picture Settings>> Enhanced Settings >> I originally have Motion Plus "off" And Digital Clean View on "AUTO" So I just turned off digital Clean View and toggled Motion Plus "on" then "Off" hoping it just needed a reset and it fixed it. (I have all types off Audio Delays on the TV on 0 and on Sound Bar at 0)
My TV Sound is all set to PCM Hope this helps

Try this, from Samsung forum:
FIXED MINE !
Our Samsung Smart TV 40 (UN40J520DAFX2a) is a simple bedroom TV from antenna, internal speakers only. Nothing else connected. Like many, the audio was delayed from the video and the audio delay setting was already set to zero.
Gooling around I pieced this together.
CHANGE NOTHING ELSE IN ADVANVED SERVICE MENU
> Enter Advanced Service Menu with TV powered off. On the remote, press Mute followed by 1, 8, 2, Power in sequence.
TV will turn on and Advanced Service menu will display on left side screen.
Using remotes Up/DN/LEFT/RIGHT/Enter navigate to:
Control > Sound > Speaker Delay Normal 10
Using left/right on remote I changed Speaker Delay Normal 10 to Speaker Delay Normal 0
Use Return button to back out to the top level of Advanced Service Menu.
I couldn't get out of Advanced menu from here so I powered TV off.
Turned it back on and sound and video is 100% in sync.
Maybe this will help others. Good Luck !!!
