I'm developing a virtual microphone that should do a simple task - play a PCM 
file provided by a client application.
I've looked through large amount of articles/forums - the information is pretty 
similar everywhere.
According to WDK I've known that there are three models of audio drivers: 
PortCls(msvad), Avstream(avssamp & avshws) and Stream Class (deprecated).

I'd go with MSVAD. However, you could simply achieve the same thing with an 
application playing to a device that just copies
its data from render pin to capture pin, as Virtual Audio Cable does. Then you 
won't have to write a driver at all :)
