Hello @John_J, I wanted to confirm a few items to summarize what you’ve tried so far:
- The core (mac) is connected to Ethernet
- The BDP3 works when connected directly to the core, but not when connected via Ethernet to the router
Have you tried temporarily disabling any firewall/antivirus/VPN you have running and see if the BDP3 can be seen as an audio device? Could you please send us a screenshot of Settings>Audio?
So we can 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 we can have a clear understanding of how your devices are communicating.
