Linn Songcast support issue

I’m running Linn’s Songcast APP on my Windows PC. Roon does not seem to find the Linn Songcast virtual device?

BTW I’m also running Linn Songcast/Roon on a Mac computer and the combination is working fine and playing music.

I have the same issue exactly. Airplay on PC works fine, but the SQ is awful! We need Roon Speakers ASAP I think.
