Just bought a Sharp LED TV and there is a slight delay between hearing sound and seeing lips move. Have cable box hooked up to tv by HDMI and have cable box hooked to AVR (Harmon Kardon AVR125) by optical...


Hi if there is an optical out on the television i would use that direct to your Harmon Kardon AVR 125, the sound would be in sync with picture, as the source is the same.

I have a Yamaha RX V800 AV Receiver is their an lip sync adjustment for internally with this amp.


This monster has a lot of built-in opportunities to tune or mis-tune the sound but nothing to deal with the effect you're addressing.

A discussion of lip sync:

http://en.wikipedia.org/wiki/Audio_to_video_synchronization

  • There is extensive use of audio and video signal processing circuitry with significant delays in television systems. Particular video signal processing circuitry which is widely used and contributes significant video delays include frame synchronizers, digital video effects processors, video noise reduction, format converters and MPEG pre-preprocessing.
  • The video monitor processing circuit may delay the video stream. Pixelated displays require video format conversion and deinterlace processing which can add one or more frames of video delay.
  • A video monitor with built-in speakers or line-out may not delay sound and video paths by the same amount of milliseconds. Some video monitors contain internal user-adjustable audio delays to aid in correction of errors.

    Haveing trouble syncing the sound with lips is there a trick to do this? also whats the best setting to get the best true surround sound by the way i have Rx-v465 with klipsch 300 home theater speakers.


    RX-V465 has auto-sync feature over HDMI. So if you have your DVD and TV connected over HDMI, receiver will communicate with your TV and set the delay automatically based on TV processing speed.
    You can turn auto-sync on in Setup menu / Sound Setup / Lipsync / HDMI Auto.
    Or if that doesn't work for you, you can set a value in milliseconds manually in the same submenu.

    Sound doesnt sync up from direct tv to the speakers


    hi, are you trying to get sound from your TV through your home sound system? I'm not quite sure what you mean about "direct TV" thing if that is a specific term. Please ellaborate.
    If you have a line (audio) output on your TV then it could be easily connected to an auxillary line input in your sound system controller. hope this helps..

    Sound/Video delay


    Lip-sync error is a widespread problem caused when video is delayed and audio arrives too soon. Widespread enough that three different manufacturers make dedicated products to address it, in fact (see review link below for those three). It is present to some extent in essentially all broadcasts and DVD?s. If you have a recently acquired DLP, LCD or plasma display it may have added enough additional video delay to make it noticeable but lip-sync error comes from MANY sources starting at image capture and continuing through post production and broadcast or DVD encoding and it is cumulative. There is usually enough lip-sync error in broadcasts and DVD's to cause a negative impact on viewer perception (Research done at Stanford showed this.) Many people don't consciously notice it until it gets very large because it's such an unnatural phenomenon ( audio can't come before the action causing the sound in the real world) we apparently subconsciously avoid looking at the faces and seeing the lips move "after" the sound from them is heard. A study at Stanford proved this causes negative viewer perception even for those who don't notice it so this is something we all need to notice as you already have. For those reading this who haven't noticed it, take a close look at the LIPS - force yourself to overcome your natural avoidance mechanism that keeps you from looking at the lips - and you will see lip-sync error you never noticed before. I think you will be amazed that you could possibly not have noticed it before. You will be seeing what JC is seeing. I even see it now on CRT TV's and am amazed I never noticed it so it's very obvious some avoidance mechanism is at work. And back to JC?s solution: I'd recommend one of these digital audio delay units. That way you can correct for ALL cumulative lip-sync error no matter what its source might be. Any one of these units reviewed will correct it ALL. With any one of these units you can adjust for perfect lip-sync at the start of each DVD or broadcast and not disturb the image you are watching during that fine adjustment. I have had a Felston DD340 since 2004 (three generations earlier than the DD740 covered in the review) but it still has the most important feature of all these units from these three different manufacturers which is their "plus and minus" buttons on their remotes that allow you to tweak the delay while watching your material without upsetting the video your are watching. My av receiver has a built in delay of 80 ms which isn't even enough audio delay to offset the video delay my plasma display adds but even if it were it isn't practical to adjust it for the changes in lip-sync error from program to program and DVD to DVD since it overlays the screen with menus when making the delay adjustment. With my DD340 (and any of the units reviewed) all you have to do is press the plus or minus button until you get perfect sync. Here is the review I mentioned: [URL="http://www.audaud.com/article.php?ArticleID=3011"]

    Sounds don't align with lip movement


    if you are saying that your tv has no sound to match the lips movements then you will have to get a tech to repair your tv the problem is in the audio circuit could be a cap or the audio output ic.if you are saying that the tv has sound but it is not syncronizing with the lip movements have your tech check the sync circuit it is possible that the operating voltage is too small to allow the sync circuit to operate.good luck my friend.
