Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
Does this occur if you play to other endpoints like the internal speakers of one of your remotes?
Does this occur with all content or just specific types (TIDAL vs local, specific file types, etc.)?
