Have an interesting issue, easy setup. Multiple Connects, connected directly to a power amp. No DSP….No processing. When all zones are grouped together a few of the players are out of sync….by a half a second. Causing an echo from room to room. The resolution is to ungroup all the zones and regroup them. This seems to fix the issue for a day or two.
To me, its almost like a master timing issue? Anyone else ever seen this?
