HD Audio lag??

Situation: We have run into an issue at a couple jobs regarding the "lag" between an HD image and its audio. Meaning, what you are hearing is about 2/10th's of a second slower than what you are seeing.

Obviously this is a problem and we are currently in touch with our receiver dealers to try and correct it. We are dealers for Yamaha, so I dont know if it is just these receivers.

Has anyone else run across this situation, and if so, how did you correct it?

I do quite often with my built-in HD receiver, and we constantly get complaints on this site. I forget the technical explanation, but it can sometimes be corrected by turning off and on the HDTV.

You are not alone with this problem, thats for sure.

Well luckily, we have the ability to create an audio delay with our Yamaha receivers. But then that creates an issue with control. When you want the audio delay turned on say for high def channels, it needs to be able to be turned off for non high def channels.

I won't go into detail about how much a pain in the ass this is, just take my word for it.

Are you getting audio delay on your on source material, or only on broadcast/cablecast stuff? Easy way to check things: If you're tuned to an HD channel that's out of sync, tune a different one that's in sync. Then go back to the first, out of sync channel. If it remains out of sync, the problem resides with the broadcaster or cable service.

I think you'll find this is usually the case.

The problem is all the HD channels have the delay.
