I have tried samples from WDM book named "Programming with windows Driver
Model 2ndEd Ebook". I have studied the samples given for the filter driver
but the problem is that when i try to do the things for the audio my audio
driver gets damaged why does it happens ????. such as changing the Device
type in IoCreaateDevice to FILE_DEVICE_WAVOUT . I have got replies from some
google groups that "you need to use Kernel Streaming for performing your
task". Is kernel streaming the right approach ???? or is there anyother way
to do it???.
