Hi guys: I want to connect two stream device driver one is a audio device driver and the other is an stream device. Can I use KscreatePin to connect two device driver. If I use KsCreatePin in MSVAD sample driver to create a pin connect to other Stream device. The KsCreatePin need a parameter of FilterHandle. How to get the FilterHandle? Does it means the Stream device driver's PDEVICE_OBJECT or PDRIVER_OBJECT ?
