Melco and dac connections

[Mal]

Hi

I have a Melco N1ZS/2 Digital Music Library (2TB) running 3.93 firmware and am having problems with the Melco "seeing" the DAC (Mark Levinson 585) on the Melco App.

I have had this problem before and turning both the amp and Melco off and disconnecting and reconnecting usb cable has fixed this. This time I have done this numerable times and followed the guidance on the Melco FAQ - no success. The drives are available on the network (ie you can see and play the music on a pc from the Melco) and Minimserver is visible on the Melco app- the actual Melco device is just not available.

Not sure if this is a coincidence but just started running minimwatch but I dont think this is the cause of the problem - although it would be good to see its features
Any advice would be appreciated
