Hello @JOHN_DAY — Thanks for the detailed report, I appreciate that!
To start, can you please provide a brief description of your current setup using this link as a guide. 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 the behavior happen if you play to other endpoints? Or is it just with the one DAC? Additionally, can you please share a full screenshot of all of the settings for that device in Settings > Audio > Device Setup?
Thanks,
Dylan
