Endpoints out of sync

Hi,

I have several Roon Bridge endpoints as well as a Roon core server. Endpoints are Raspberry PIs some with Hifiberry DAC, Hifiberry Digi, and some without. They do not seem to be completely in sync. I suspect that the issue is that there is some latency differences in the DACs that causes this. Is there some way to configure delays into the end points so I can get them to line up more accurately

Thanks,

Carl
