I’m having this exact same issue with Roon losing control of the connected audio device. iPad, iMac, iPhone. If you scrub through songs quickly or change DSP settings, Roon will lose control of the audio device. It happens ALL THE TIME. And I can’t believe more people are not complaining about this bug. It was NOT there a few releases ago. This issue just started when Roon was recently updated.
Welcome to the community Mark.
People do complain on here and some issues get sorted, whilst some don’t. The latter, are most of the times blamed on our networks and get swept under the rug.
Fun times

Hey @Mark_Radogna,
It’s been a while since this thread was last active, and I wanted to follow up and see if you still need help with the audio devices connection.
We’d love to help
