Creating a virtual soundcard
Posted by gerhard on November 24th, 2004


Hello!

I am trying to implement a virtual soundcard, has anybody done this
bevore? I think I need to get some help from a specialist because I
have no idea about the structure.
Do I have to implement a ISR? Or should I trigger with the mounted
soundcard? If somebody could give me samples to look at or good
recourses (I checked msdn but no goot resources found) I would be very
happy!

TIA

Old-style WINMM driver with wodMessage function is the simplest solution.

No for sure. Only real hardware has ISRs.

option.

I have some general questions about the DDK:

What output is createt? A *.sys File? I haven't found any basics about
driver development ... Should we all start as experts? The samples
which are provided with the DDK are not that helpfull as I want them
to have.
It should be an quite easy setting up a input and an output buffer for
a virtual soundcard. But the structure isn't clear to me.

WINMM is well-supported in w2k and XP.

WINMM driver is a DLL, you can even write one via MSVC IDE, provided you have
the necessary header files.

Kernel-mode driver is SYS.

Walter Oney's book is good
