@Bill_Underwood, definitely deactivate your VPN (for now), Roon is not designed to work with them and they tend to interfere with Roon.
Can you post a screenshot of Roon’s Settings → Audio tab? What model/year is your MBPro, and how is it connected to your network? Also, can you confirm that all of your devices are connected to the same subnet (where their IP addresses all match aaa.bbb.ccc in their aaa.bbb.ccc.nnn IP address)?
Robert, thanks for your suggestions. I just figured out that I had to restart my Mac, and it cleared it out and now it works. Feels like a duh moment, but glad it’s working.
