i just want to capture/feed the playback/capture(mic) data per application
basis and i don't need mixing to get in my way.
i am targeting any NT based OS ( till Vista. Vista is not supported)
but the wodmessage model is in use till XP SP3, so i can use it, but the
documentation /samples seem to be scarce. the wdmaud.drv executable is based
on this model.
Anyways, if you can let me know how the kmixer would create n no. of
streams( n different media players playing songs), without mixing any of
them for a WDM driver based of MSVAD multstr, i would be happy
Anyways, the issue i raised earlier in this thread, has been solved.
Thanks for everyone to help me out.
Regards,
Vipin
