I develop driver for virtual audio device. As base for driver I'm using
simle driver from msvad sample.

My driver in topology minidriver has only one input pin - microphone.
In topology I have 2 nodes volume and mux.
connection are: microphone pin -> volume control node -> mux control ->
topology output.

Wave miniport has only ADC node and 2 pins
: input from topology and capture pin for aoutput PCM stream (16 bit, mono,
48 kHz)

When my driver start Im registering connection from topology miniport to
weve miniport.
Driver work - I can record sound, I see it as audio source etc, but I can't
see volume control for it in SndVol32 program.

simple driver have the same problem. I see for it volume control for
palyback, but if I change to Recording volume I can't see any mixer line's.

What I need to do to see my microphone line in Sndvol23 program ???


Other problem symptoms:

In KSStudio when I initiualize filter factories for Topology and wave from
KSCATEGORY_AUDIO I can see topology that I describe in Driver
KSCATEGORY_AUDIO_DEVICE filter factories I see Data input pin and recording
control pin and 3 nodes: ADC, sample rate converter and supermix.

This look like windows can't use my topology, when driver starts. But I see,
that topology minidrivers method are called.

I try add to topology mute control, remove mux control and stiil no result.


ps. my virtual device is enumerated by swenum.


My second question:
When in registry i shood write localized names for my audio componets (for
example for topology nodes and etc)
