Further to this, you can use the wave API to obtain a device interface by calling waveXXXMessage with DRV_QUERYDEVICEINTERFACE and DRV_QUERYDEVICEINTERFACESIZE. You can then use that device interface to send IOCTL messages to your driver. This is documented in the WDK under "Obtaining a device interface name".

Hello debopam,I require my XP audio driver to respond to my own proprietary message; using waveOutMessage.Only a legacy user-mode audio driver, registered to work together with winmm.dll, can process user messages. A WDM driver can process only IOCTL requests (standard IOCTL_KS_PROPERTY property request with KSPROPSETID_XXX/KSPROPERTY_XXX identifiers or proprietary IOCTL codes). Messages sent via waveXxxMessage are not routed to WDM audio drivers.
