Is this for Speakerphone/Call progress type functionality on XP?

Subject: [wdmaudiodev] Streaming kernel audio from non-audio device

Dear all.

I am a new to the kernel streaming, so I would like to ask the
following.

There is a non-audio device (modem). There is a necessity to stream an
audio inside the kernel without affect on the other audio streams. For
example, from system microphone -> into sound card -> into splitter ->
into modem driver; and back from modem driver -> into kmixer -> into
sound card -> into system speakers. 

What is a right way to do that? Is it necessary to make a second virtual
audio driver? Or is it possible to connect directly to kmixer and
splitter?

Thanks, Stanislav Petrenko.
