Problems - with airtunes


After I have intalled ATVFlash in May - everything works fine - except for using multiple speakers from my Itunes. 

I can see my Apple TV - I can choose my Apple TV as speaker and it connects but there is no sound from the Apple tv. The rest works fine with streaming podcast )with sound= etc.

Please notice I have enabled Airtunes at the Apple TV



Do you happen to have the 'Overflow' item installed?
