[I had posted the same message to ntdev@xxxxxxxxxxxxx but realize that this is a specialized list for such stuff - hence posting it here] Hi all, I need to write a virtual driver which acts like a microphone. Something like daemon tools, but which provides a virtual microphone. This is for providing interactive-input to an application which uses audio input (I don't have any control over the program & don't have it's source code), and provides a selector for which device to use for input. So if my driver appears in the list, I can get input from it. What sort of driver must I write? How do I tell windows that the hardware is present when it is actually not? Is it possible to load the driver before running the application & unload it after the app exits? Also, any idea how this driver can be loaded into a Terminal Services session? My platform is Windows 2000 and above. I am a newbie to driver development but have read some of the DDK material. Any suggestions/hints/links will be much appreciated!
