Samsung LED 46B8000. Sound sync, audio out of sync

by MrPumblechook / October 25, 2009 9:10 AM PDT

Hi. I've just bought a Samsung LED46B8000. The problem is that the audio seems to be a very slight fraction behind the picture. I don't have any external speaker set-up. I'm just using the internal speakers.

This happens whatever the source, whether it be broadcast digital TV or watching a Blu-ray via PS3. Is there a setting I can change, is this a fault with my tv set, or is this an issue with all the LEDs? Would using external sound remedy this?

Samsung LED 46B8000. Sound sync, audio out of sync

MrPumblechook,

If it's only happening with the HDMI connections, and not analog connections, that would likely indicate an issue with the TV.

But to answer your question, in many cases, receivers today have an audio delay. But if the audio is already delayed behind your picture, that may not necessarily be a fix.

Can you tell me what is connected, and which cables are used?

Thanks for getting back to me. The lip sync problem happens when I am watching UK digital broadcast tv via the built in digital tuner. I think there is a built in analogue tuner but I don't know how to change to it.

Also when using the PlayStation 3 to watch Blu-ray or dvd content with a category 2 HDMI cable, and Xbox 360 dvd or (legal) video files downloaded via Xbox Live - connected via HDMI.

If this problem is unique to me, I will take it back to be replaced. I hope it isn't a design fault.

MrPumblechook,

That may be the best option. I don't see a lot of these issues from anywhere - including the UK. (Though that's not to say that they don't exist just because people don't post... but anyway...)

Keep me posted.

I have the 6000 series led, and it has the same audio sync issue. It happens from
most inputs, and it happens when I'm listening through the internal speaker, as well an external 5.1 setup. Anyone have any insights?

eldonhenley--2008,

If you're listening through both simultaneously, that may be the source of the problem.

The speakers on the television have a digital signal sent to them. Porting out the audio will require signal processing in the receiver and cause a delay. It's recommended that you choose one or the other when choosing your audio options.

I'm not listening through both (tv and receiver) at the same time. I just meant i was testing both sources individually. But I did figure out what the problem was....

I had both my HD cable box and Xbox360 audio outputs set to "passthrough". Although this allowed me to hub everything into my TV via HDMI, and output Dolby 5.1 via one Optical (TOSlink) cable to my receiver, the signal seemed to have been lagging since it had to travel such a long distance (source > hdmi > TV processor > toslink > receiver processor)

I have ordered a 2:1 Toslink splitter that works both ways. This way i can plug Xbox and Cable box into the splitter, and plug the splitter into the single receiver input. The only catch to this: only one source can be on at a time (which is completely fine, not to mention energy saving)

UE55D6530 - Sound Delay

Hi,
I have an issue with UE55d6530 using a Samsung HT-D5500 suround sound. I have been massive delay in picture as audio was coming through first using a Optic audio when watch tv and playing sound from suround sound. Replaced both TV and Blu Ray SS. No difference. Then I started using HDMI Arc to process the sound from TV when watching Sky which seems better and now I get lip sync issues similar where the picture is before the sound but only after a time of watching or when selecting certain recording on sky.
My old LCD and Scart surorund sound I never had any problems. Dont understand what the problem is. Spoke to so many people trying to find out what could be the cause and no one can help they just kept replacing all the devices.
Must be a samsung deisgn floor as I cant think what else it could be?

What folk should be telling you
by R. Proffitt Forum moderator / November 17, 2011 10:30 PM PST

Is that the changes have been deep. That is you find the best effect when connected like this:

Source -> HT system -> HDTV

If you do other wise you usually see the worst of the lipsync issues.
