Hi,
The question is not if we can play a wav file in Kernel mode… For a good
practice these kind of notification should be done from the User mode
application and not from kernel mode. Hence, you can write a service which
will wait on an Global event that is signaled by the kernel mode driver on
reading a data. On signaling the user mode service will do the job of
playing the wav file.

Regards,
Prasanna.

Write a user mode service, talk with your driver and use the normal
wave api.

You are kidding, Right? Even IF it’s possible, which I doubt, WHY? This
definitely violates every tenet of good device driver layering, architecture
and design. Please let me know what products your company produces so I
know not to buy any of them.
