How to stream audio via MinimServer from the sound card inputs on a local PC?

[n3mmr]

I'd like to stream multichannel audio from a multichannel USB audio sound card's inputs to my UPnP control points and renderers.

How should I go about doing that??

Can anyone suggest software on a PC (Windows or Linux) that can stream the inputs on a sound card in a way that Minimserver and/or minimstreamer can make available to UPnP control points and renderers, and also tell me a little about how to set up MinimServer and friends to handle this?
