by accident, and could cause bad noises during music cross-fades.
This wasn't a problem in 0.6.0 since all music is sampled at 22050 Hz,
which is the most likely output sample rate for ScummVM, so the converter
didn't actually have to do anything. Now, however, the output sample rate
could be anything.
I've given the music streams one converter each. In BS1, which uses similar
music code, it was already necessary to do this since some of its music is
sampled at 11025 Hz.
