Due to a change in the OS X networking stack since OS X 10.13, we have found that our multicast clock traffic can be interfered with on some Mac OS systems, resulting in DVS periodically losing sync with the leader clock. We are working on a resolution for this in the next DVS release. We have not observed any impact on the audio.A workaround for this issue is to use an adapter such as USB or Thunderbolt to Ethernet instead of the built-in network port. Running DVS at a lower sample rate such as 48KHz with fewer channels has also been found to resolve the issue.
