There is a fadein, but it blocks.  So I'm not sure if you'd want to use it.

Another option is to change the volume every time in your main loop as
you loop around.  Check how much elapsed time has past, and adjust for
that.

You should be able to set the mixer at 44, and it will mix both for
you without changing it.  Try both and see :)
