I still have a few SB3 running, augmented by a couple of RPI3 B+ with HiFiBerry and PiCorePlayer. The other day I was playing music in sync in three different zones that were all audible from the same location in the back yard. The two slightly more distant zones were PiCorePlayers. The closer zone is a SB3 into under-eave speakers.
There was notable difference in timing between the three zones. This manifest as a kind of delay. I could hear every snare drum hit echo'd, as if it was echoing off a far back wall.
Of course, I would not expect them to be perfectly in sync, since the speakers are at physically different locations. This was more delay than I expected.
This made me wonder if there's any adjustment for latency in PiCorePlayer?
I swapped out the SB3 for another RPi, and everything was then in sync. In all these years I'd never listened carefully to multiple zones, at the same time, where each was using different hardware.
