Audio sync delay - 75NU800 & HW-N850

AviFC — Thu, 13 Dec 2018 20:35:50 GMT

Just spent $5000 on this setup and the audio does not sync, Samsung customer service has no clue. The video is processed faster than the audio so all of the built-in sync options just make the problem worse. Any ideas?

I see many threads on this but no actual clean fix. How could Samsung not have a fix for this?

Hello,

can you tell me what type of connection is made between the soundbar and the TV?

Re: Audio sync delay - 75NU800 & HW-N850

HDMI ARC as that is the only way to use Dolby Atmos.

I was on the phone with customer service today for an hour, complete waste of time. I can get into the service menu but they would not provide any guidance on this, only on regular menus. I need the audio to sync -, the menus only allow to sync +.

Hello,

I hope we can found a solution together, so please tell me :
Did you perform a COLDBOOT of both devices?
Have you tested with another high speed HDMI cable?

Yes, we did a factory reset on the TV. The Soundbar I was told to unplug for 30 seconds and replug. Tried a different HDMI no difference.

Can you try this manipulation please.

Press the SOUND CONTROL bouton and select SYNC in Sound Control, and then set the audio delay between 0~300 milliseconds by using the Up/Down buttons

I did that. The problem is I can only DELAY the audio. I need to ADVANCE the audio.

Did you tried to update your soundbar?

Re: Audio sync delay - 75NU800 & HW-N850

AviFC — Sat, 15 Dec 2018 15:24:47 GMT

It is connected to Wi-Fi so should be updated automatically. How can I tell if it is updated?

To update my soundbar via USB key, proceed as follows:
1. Insert a USB flash drive containing the firmware upgrade (downloaded from Samsung's website) into the USB port on the back of the soundbar.
2. Connect the power plug of the soundbar.
3. Turn on the sound bar.
4. Wait 1 to 2 minutes.
NB: you can put the soundbar on any source.

5. After updating the soundbar will turn off automatically.

Done. No difference.

One more last question

do you have the offset sound on all sources?

Re: Audio sync delay - 75NU800 & HW-N850

AviFC — Sat, 15 Dec 2018 21:57:14 GMT

Yes, all sources but some are worse than others. Netflix is really bad.

Sorry for saying that, but i think that your SoundBar needs really to be repaired, there is nothing else to do 😞

Why? This is clearly a software issue. The soundbar works fine, I just need a solution to slow down the audio.

Was this resolved? I have bought this sound bar and netflix sound is out of sync with the visuals!

Re: Audio sync delay - 75NU800 & HW-N850

Nope. Very disappointing service from Samsung on this issue. I just used an optical instead of HDMI, so I gave up Dolby Atmos so I could get lip sync. Not a happy customer.

I just purchased this soundbar and have the same issue. Video is ahead of audio. Was thinking maybe I can slow the video feed on the TV (a TCL). Let me know if you figure out a solution.

Also experiencing extreme audio delay on both hdmi arc and optical outputs of my samsung Q6F 75”. played with all settings including sound resets, PCM HW_N850. Need to slow down picture processing or speed up audio.

I bought an optical switcher on Amazon.

Now I am running an optical direct from the switch with a single out to the soundbar.

No delays, but needed extra equipment but more importantly unable to transmit in Dolby Atmos which is the whole point of buying this soundbar. Extremely disappointed that Samsung has not fixed this issue, this is pretty much false advertising.
