I don't care much about the extra conditional, if the dsound mixer did
proper interpolation it would be doing much more expensive operations
anyway, and if it was supposed to be fast it should probably be using
SSE intrinsics when available. It just looks questionable to me to use
a different scale for positive and negative values.

Come to think of it though, doesn't ALSA accept floating point values
itself anyway?
