I have been using my Network Bridge with Roon for about a year, without any problems.
On a whim, I decided to try using Mosaic and uPnP, and was shocked to find that it sounded significantly better to me than Roon (I know that it shouldn’t). This makes me tempted to use it all the time, despite the loss of functionality, but…
I find that I can play a few tracks and then it stops, and I get a message saying that the Network Bridge can’t be located, and that I should search for another device. When I do this, the Bridge is located again, but I may or may not be able to restart the music.
Details of the system:
Control via iPad Mini running IOS 13.2.2 (I’ve tried deleting the app. on this and reinstalling several times).
Synology RS214 NAS
Draytek 2860 vn plus router
Cisco SF 200-24 switch
Netgear mini switch (for hi-fi/video)
Cat 6 ethernet cabling
Mac mini (Roon Core)
Nagra Classic DAC
All network connections are wired (apart from the iPad).
Of course, if we can figure out why Mosaic sounds different from Roon (and fix it) that could be a solution.
