Hi Mike,
To play music resident on your computer I would suggest using Windows Media Player (I am assuming you have a Windows machine). After you start to play a song their will be an icon in the upper right that will display a little green arrow. If you select that your AxiomAir will show up as an available UPnP device to play to.
For getting your NAS working it may be best to give us a call at 888-352-9466 so we can get that working for you. The False mount means your AxiomAir is not seeing your NAS. It should just be a matter of inputting the IP address of your NAS, naming it, and then selecting the share folder. We will figure that out and get it working for you.
