Thanks a lot!
I installed it and after restarting MB, Windows asked permission to use the Network so that part seems to work.
If you know of a simple way to test this (on this or another PC connected to my network) before I decide to buy the amplifier I'll be glad to hear about it.
There's a good solution to this, which is pretty straightforward and free. On your second machine, the one which you won’t to hear MB, download and install Ohplayer, available via the PC 'Try it now' icon on this page:
http://openhome.org/pages/use/index.html (There's also versions for Linux, Mac's and Pi's). Having done that go to: C:\Program Files (x86)\OpenHomePlayer and run the executable 'OpenhomePlayer'. It will run in a minimised state on the taskbar. Finally, return to the PC on which MB is installed and select the player tab from preferences; and, if you've already installed MB's UPnP-DLNA Plugin, you should notice that your second machine is now listed as an audio output - select this and hopefully the job is done! Music from MB should playback on that second machine.
On a side note, if you’re looking to buy an amplifier or receiver to stream music from MB, or indeed another source, you should be aware that many hi-fi manufactures have developed their own proprietary, interpretation of what the UPnP protocol should entail and ultimately this implies that there isn’t really a common, fully adhered to standard to streaming music via this method. This could mean there are issues with steaming music and possibly it may not work all. IMHO this doesn’t mean that there’s anything wrong with MB’s UPnP-DLNA Plugin – I for one have never experienced any issues with it. Fingers crossed that streaming will also be good for you, but if it isn’t I suggest you try running BubbleUPnP Server in the background (
