"null" audio driver

Does anyone know of an existing "null" audio (software)
device that can install without hardware and provide the
interfaces that programs such as Windows Media Player need
to see in order to believe that an audio device is
installed?

Any advice would be appreciated.

Thanks.

To clarify what I'm trying to accomplish:

I've got applications that use IE with Flash, Media Player
and the Real player to download web content. Flash and
the streaming players require an audio device to be
installed in the machine. Ideally, I would like to get
this to work without needing audio hardware, hence the
desire for a virtual device that interacts correctly with
the OS (Win2K Pro) but doesn't require hardware or
actually attempt to make any sounds.

Thanks for the pointer, but their application still
requires that a "real" sound device is installed in the
machine.

Hello,

You might want to try the MSVAD sample in the Windows DDK, under
\src\wdm\audio\msvad

This is a virtual WDM audio driver that implemetns a timer-based interrupt
mechanism to simulate rreal DMA. The IDmaAdapter code copies data to
memory instead of using actual DMA.
