Hey @TaeHyung_Jeon — Thanks for reaching out, and apologies for the difficulties here!
We’d love to take a look at this and help you get things running better. So we can better understand what me be happening, may I ask that 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.
So we can gain some additional insight into this, please see the following:
- Do the dropouts occur when playing to all endpoints? Does it happen for all content?
- Can you share a screenshot of your signal path in Roon?
- Have you tried power cycling your Core machine, endpoints, and networking hardware?
Thanks!
Dylan
