Man, that would make my job so much easier. Have you been working on this
Keith? If so, I'd really like to what you have. Right now I'm doing classes
by appending them to the front of the names of streams and then just
checking every stream to see what class it belongs to a la module-match.

Also, any word on the fixed-point resampling/volume fixes you mentioned in
the same post?

It sounds like we're working on similar stuff. By that I mean embedded
systems in need of fixed-point math operations and audio class policy.
Perhaps we could collaborate.
