The wodMessage driver model is generally not well supported on any of the
recent releases of desktop Windows. You should consider the WDM Audio driver
model. See http://msdn.microsoft.com/en-us/library/bb870472.aspx.
Is there a particular reason you need to implement a user-mode driver of this
type? What version of Windows are you targeting?

Subject: [wdmaudiodev] sample User mode installable multimedia driver
Hi,
i am trying to write a user mode installable multimedia driver ( basically
i want to implement the wodMessage ).please visit
http://msdn.microsoft.com/en-us/library/ms713504(VS.85).aspx
i can see my device in the list, however, when someone tries to open the
device, i receive a callback argument with value 0, which is not valid
so no one is able to open the device( AFAIK the device will open only when the
callback is sent, but since it's a value of zero, it's of no use )
can someone help me out here.
i am also trying to search a sample but in vain. Can someone please point me
out to the sample or what am i doing wrong or how should i do it.
waiting for your help
