Hi, I have writtten an audio driver.(user-mode DLL) I am facing problems in getting it installed. After installation, it is displaying under "Sound, Video and game Controllers" in control panel. But it is not displaying as audio recording device. I am missing few registry entries. This driver is only for recording. No hardware required. Anybody advice me what all are the registry settings required for audio driver which is a user-mode dll? or how to install the driver correctly? Thanks, Sreeram
