Are your program a mixer application or recording application ?
If the sound card does not support multi-streaming ,
the mic is one of the choice in the "Capture Source" controls
If your application can find "Input Source" in your sound card , this
mean that your sound card support multi-streaming capture
i.e. there will be more than one "Input Source" controls
