If everything is working correctly, when music is played in MediaMonkey the same music will play on LMS and the Squeezebox device (MAC Address). It will override any music that was playing on the Squeezebox system beforehand. If the addressing for the music locations is in a different format due to the use of Sparc-Linux on a NAS then the Squeezebox music will stop but the MediaMonkey music will not play on the Squeezebox system.
A QNAP NAS has never been tested on MonkeySqueeze so it may not work, however there are a couple of things you can do. You may have done all or some of these suggestions. Read the section in the user guide "Logitech Media Server on a NAS Device". As stated in the text only ReadyNAS and Synology devices have been tested and known to work. The Synology NAS selection may also work for QNAP devices. Go to the Options page > Logitech Media Server on a NAS using Linux, and check the "Synology NAS" selection, then play music on MediaMonkey. If unsuccessful then uncheck Enable (aktivert) and leave "Synology NAS" checked, then play music on MediaMonkey. After this there is not much you can do apart from changing the format of the music folder addressing in the text boxes.
If the QNAP NAS does not use Linux and uses windows then deselecting all the selections in "Logitech Media Server on a NAS using Linux" may work.
Prior to Katteman and myself fixing the comms with ReadyNAS and Synology Linux NAS devices I install the PC version of LMS (Squeezebox Server) and used it to communicate successfully with MonkeySqueeze/MediaMonkey. The NAS and PC versions of LMS can co-exist happily provided you give the Music libraries different names and select the relevant library on your Squeezebox devices (all info in the user guide). Also the PC LMS does not need access to your music collection, again see the user guide. If you do this, at the very least you will see how the setup works correctly, which may help you with the NAS comms.
Goodluck, hopefully this info has been helpful. Let me know how you get on.
