AirPlay audio sync issue

This may have already been covered so if so please forgive the repeat. I have an Apple TV (Gen 1) playing through a Samsung Plasma screen which was playing the music with a noticable delay compared to my Mac and to a Bowers & Wilkins, Zeppelin Air speaker.

The Mac and the Zepplin where in sync but the Samsung was out. I experimented with the dalay setting per one of the previous posts but the thing that made the most noticable difference was setting the Samsung's sound to "Standard" rather than Music, Movie, Clear Voice and all the other "processed" setting they typically offer. This can be done in the screens Menu settings.

Hope that helps.

Thank you so much, I did't believe it could be the TV in my situation - because I don't play sound through the TV, but a Denon AVR-3311 - but all I did was turn off the TV and after the amp did some cycling the sound came back IN SYNC. Again, thank you so much.

I have a similar setup--Denon AVR-891. Turning off the TV made the AirPlay go back in sync, woohoo!

Since we typically control music playback with iOS devices (Remote.app is amazing), the TV being off isn't the end of the world.

Thanks all!

Same think here, but it was not my TV but my amp (LG HX995TZW). I had a driver update who modified a settings and a delay appears with my others airport express.

Just to need to set up the setting to 0ms and everything is great now!

Thanks to all on the thread!

I have a apple TV 2ª Gen link by HDMI direct to my LG TV and a PC. Unfortunally, there is not a sound delay option in my the TV set UP. I also tried to set the tv sound to standart rather than "Movie" or "sports" as did the other commenter, but it did not work. Anyone has another idea? There is no use in multiple speakers if they are delayed to each one. Air play multiple speakers need a manual sound delay control urgent. Any help will be welcomed.

I've got the same issue. I'm completely updated on all ends, both the Apple TV, and all software updates for the iMac are good.

When playing to an Airport Express, the iMac & express are perfectly in sync..

When playing to Apple TV 2, audio is not in sync.

I also, do not have the ability to connect with optical, only HDMI.

Router is is the latest AirPortExtreme

The problem is with the apple tv

I have media files that won't sync since the last software update to apple tv 2, they used to.

They still stream perfectly over plexto my imac, ipad, and iphone

The best solution is to jailbreak the apple tv 2 and turn it into a plex player

Hey guys I have a similar problem.

Conditions:

1) Aiport express connected to logitech speakers (works fine)

2) sony home theatre connected directed to mac via a stereo mini plug (where you put headphones)

So my problem is when I play the music through itunes on my computer the speakers that is connected to the airport express is delayed. Is there a way for both to play at the same time and volume because I have tried tweaking with the individual volumes to see if it will work but nope. The best I could do was let the logitech play louder than the sony speakers since it is delayed. If any of you guys have any idea on what to do let me know I have a party in 5 days. Thanks in advance!

Are you sure the sound via the Airport Express is delayed and it's not the other way around?

If you read all the previous entries you'll realise the culprit is either an AppleTV, an AV Receiver or a new TV. This is because all of these process 5.1 (or more) sound channels and Video which requires buffering and processing to keep everything in sync - which takes time.

It is impossible to create a proper 5.1 AV signal without inducing a delay between source to output.

Airplay, Airport Express, and simple Logitech speakers do not require any processing.

As you do not mention an AppleTV, or that your TV is turned On at the time you are suffering this problem, I can only assume it's your Sony AV amp that is causing the problem. You need to check the manual to see if there is an option to turn all Delays off, like a direct Music mode.

From what I've seen on AV forums, there are some older/cheaper AV amps (and TVs) that do not have such set-up and simply delay the audio output regardless of whether signal processing is needed or not. Others, as mentioned here, are smart enough to know when you turn the TV Off, there is no longer a requirement to sync the sound to the video, so buffering and processing is not needed and revert to music mode.

Hmm interesting. It sounds like its coming from the aiport but hey if so many of you ay its the other way then I guess. Now the question is I can't find a way to turn off the delay. I have looked through the instructions and online but nothing. I have a Sony DAV-HDX589W if anyone can find it for me. Thank you HTH!

The only way I can think that the Airport could be causing a delay is if your WiFi signal is VERY weak. But if that is the case you should hear the occasional pause as it buffers the signal. As for the Sony, you have the manual so if you can't find the answer...

To tell you the truth I have no idea. I have tried everything I can think of and still nothing. At a low volume you don't hear the delay but as the volume increases that is when it's at its worst. I looked in the manual but the only thing about delay is for picture to audio delay for DVD's so I have no idea how to turn the **** delay off lol. I tried calling SOny but you already know how that discussion was.

Yes, which is why some (like myself) reported that turning the TV off resolved the issue because the AV amp was smart enough to realise there was no longer a need to do all the lip synching processing that goes on with 5.1 AV. Others have indicated they have been able to manually turn it off either at the TV, or some 'standard' or 'music' setting in their amp.

You appear to be in the unfortunate situation where you don't even have manual control :-(

I just mention this because some think it is an Airplay problem, or something that Apple should fix, when the simple facts are that Airplay is not intended to be a 5.1 sound system, it simply sends a digital signal. What you do with that signal depends on how much you spend on AV equipment, and clearly 5.1 AV has delay built into it.

The solution to this problem should ALWAYS lay with the AV equipment, unfortunately some equipment does not allow you the necessary control.

This by far one of the most frustrating things to experience. And you would think that you spend all that money and you should get what you pay for.

I have been using an Apple TV 2 and an Airport Express as music streaming devices for some time now.

Both were perfectly synced all the time until I installed one of the latest Apple TV updates (must have been some time in summer).

Since then it's been impossible to get the music synced.

I guess we'll have to wait for another update to fix this :-/

This worked for me as well so thanks!
