Connect sync issues

Giles
I have same issue of delay on speakers connected through Yamaha AV Receiver. Causes a really annoying echo. The AV was connected to the Connect using the digital optical cable. However the problem goes away and good sync when using the line out RCA cable on the Connect - not ideal but it works.I am afraid this won't help Giles whose problem is caused by a different issue on a different type of amp.

Im having the same sync issues on an onkyo susyem. Among the discussions i dont see any technical assistance or a sokution from sonos. Has this been resolved by anyone in a format that i can follow?
Switch on the amp? Feature in sonos app?

This is an Onkyo problem, and the Onkyo solution is to run it in stereo or direct mode via a switch on it, to eliminated the lag it adds in other modes.
