Axiom Home Page Forums General Discussion The Water Cooler High def audio sync problems

Having the player decode to PCM would actually take more CPU power.

I'd say the Denon is to blame. For some reason it can't manage to decode the audio and pass the video on, while keeping both in sync.

Compressed audio does have a variable size, so there will be a different number of bits for each video frame. The receiver has to unpack those, and still keep the timing with the video right.
