Win8 Remote RoonSpeakers no sound

Using Win8.1 tablet as Remote and private audio output via Devialet AIR, sounds suddenly disappear though music is still running (as per the display showing music progressing). This happens regardless in Exclusive mode or not.

Core is on Mac Mini.

does this happen on non-devialet air?

If it is not AIR, then there’s no private zone audio output available. AirPlay is global, isn’t it?

I mean, does it happen when you play out the system output private zone on the tablet?

I will play through PC speaker and see if same thing happens.
