I'm not sure if I can help here.
If you want to bypass kmixer on a non-HW accelerated card, the only way
I know of is using DirectKS from the application (and that's maybe not
as easy as you think) but the simple solution to your problem might be
to adjust the "Wave" volume. Set it to maximum.

Subject: [wdmaudiodev] Kmixer mucking with data?


Yesterday I posted a query titled - "Audio data conversion in apps?". I
did some more work after that, writing a simple little app that sends
raw PCM data to my device via waveOutOpen and waveOutWrite. The app does
absolutely no processing of the data. Turns out I get the same data in
the driver as in the CoolEdit case. So, my only conclusion is that
kmixer.sys is changing the data. How do I figure out exactly what kmixer
is doing, and how do I return the right info / caps / etc. from the
driver to get kmixer.sys to leave the data alone so it comes to the
driver untouched.

Thanks,
