AppleTV+AirTunes=sound out of sync

[TRUCKSF]

I have 3 remote speakers set up with AirTunes using Airport Express throughout my home. Turned on the new AppleTV AirTunes feature and played a song off my iMac. Sound is in sync on all the speakers EXCEPT through the AppleTV/AV receiver speakers. Sound lags coming out of AppleTV. Anyone else having this issue? Any solutions?

Same thing here

my mac and express are in sync but the appleTV is really late on the sync.
