Hi @support,
I’m having an issue with zone audio sync. I have 3 Roons:
MacOS (core) running High Sierra, v1.4 (306)
MacOS (bridge) running High Sierra tried with and without a USB DAC, clock master = default, v1.4 (306)
RaspberryPi (bridge) connected via the built-in HDMI to an Onkyo amp, clock master = 1, v1.0 (141)
All are connected by a wired gigabit network.
When I group the two output zones, and start music playing, they are perfectly in sync for about 5 minutes then gradually drift apart. Pausing then restarting the music resyncs for another 5 minutes or so, before drifting again.
I’ve tried also using a Linux core in an LXC container, and combining the MacOS core and bridge onto a single machine (with and without the USB DAC). In all cases the sync issue persists. I haven’t tried adding a delay, as the sync delay isn’t constant - it grows over time.
Any help would be much appreciated.
