Because the mixer itself in the sound card has such a volume control for
PCM. It's either an attenuator or a gain control at the output of the

On some sound cards it is possible to have PCM level set too high,
generating clipping or other noise, which can't be undone by lowering
the main volume control.
Sound cards also vary somewhat ... for some drivers it isn't possible to
choose a PCM level that will work correctly on all cards.

I just play, to see what sounds best.
Another example ... on an emu10k1 here there are bass and treble tone
controls somewhere between the PCM control and the output controls ...
and the bass and treble tone controls can generate some bad sound if the
PCM level is too high. They can be switched out though.
