Adding 'Audio' tab.
Volume indicator of MDM16AA display now working.
Adding server side dependency on NAudio.
It was decided to have a server side dependency so that we could implement
new fields control such as:
* Volume indicator
* Mute indicator
* Spectrum visualizer
* Meter visualizer
* Fancy visualizer
