Sorry, what do you mean 'sync' trouble?
Is there a fixed delay, or a random/changing sync delay?
If fixed, just use 'Extra Delay' to counter it, as per the User Guides.
If random/variable, there is nothing you can do.
That will be a WiFi/Resolve realtime playback issue. Nothing to do with LightSpace.
There is definitely no delays within LightSpace!
Note: we do not recommend the use of WiFi (as stated in the website User Guides) due to issues with random delays/interrupts...Steve
