Pause button grayed out?

Hi,

I’m new to Audirvana today from roon. All seems to be working great apart from the pause/play button being grayed out and therefore unresponsive Kind of an infuruiating issue.

I’d be most grateful for any solution.

I’m streaming Tidal on Windows 10 to a Cambridge Audio cnx v2 streamer, pause play works from device but not the app.

Thanks in advance!
