Eric,
My music collection is stored on my MBP HD. I Imported my music from iTunes to Roon. Also, I can launch and listen to iTunes without this issue.
Yes, if I play music directly from my MBP speakers, Roon will automatically pause. Very strange. I can’t stress to you enough that this only happens 1 time upon the initial launch within 10-15 minutes of playback. Roon automatically pauses playback, then I just press play (un-pause) and it resumes playback from where it paused and never happens again until I relaunch the next night. This happens whether I’m listening to my music library or Tidal files.
Thank you,
Joseph
