Maybe. But you certainly do not have to export that uglyness to
userspace.

...which is very bad interface for applications. See my other
mail. Applications should not have to play with fast/medium/slow,
explicitely. Instead, on opening /dev/dsp, you should power up the
sound system (and maybe adjust cpu frequency if
neccessary). Application should not have to do echo fast > somewhere
before opening /dev/dsp.
