Hi @Jean_Bourassa and @Mark_Labow,
Your posts have been moved to the support section of the forum.
In order for Roon’s @support team to better assist 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 they can have a clear understanding of how your devices are communicating.
Can you post screenshots of your Settings > Audio tabs that include the 390? Also, a screenshot of your Device Setup of the 390.
FYI, I have the Moon 390 and do not have this issue. Hopefully Support can help you out.
Cheers, Greg
