Second life Backing tracks.

I am running windows 7 through the exe. installer.

I play guitar and sing on secondlife and am trying to make up backing tracks to stream into it. I have succesfully imported a backing track and recorded myself singing with it. I have enabled the stereomix function but dont seem to be able to stream it in the normal way. Also I don’t seem to be able to record voice over with stereo mix enabled as it flatlines. I have to make the recording using the built in (realtek) mic and then change it after. Does anyone know the solution or able to point me in the direction of a tutorial on this.

Many thanks

Bill

That is the Audacity job done.

Export that mix in a format supported by whatever other software that you use, and the Audacity task is complete.
Audacity is a stand alone program and is not designed to integrate into other applications.
