Roon not outputing sound to DACs [Resolved]

On restarting Roon this morning I discovered that Roon had disabled my Dacs/zones after enabling both Dacs/zonesI still have no sound Roon is showing that the track or radio station is playing but there is no sound from my desktop speakers or headphone setup. This follows an update to Roon yesterday which played fine for the rest of the day. Both Audirvana + and iTunes are playing content without a problem as usual.

Roon version - 1.3,build 274

Desktop - Audio GD R2R 11
Headphone setup - Chord 2Qute


After a couple of restarts the problem has resolved itself
