Two colors simply isn't enough. You need a color for low, a color for middle
and a value for high. And then you haven't even looked at a fourth color for
mute/off.
And fading from green directly/linear to red gives an ugly brown in the
middle. It looks much nicer to go across yellow. And then you can really use
that third color to stand for a special step, not just "in the middle of the
slider".

If these colors are taken from the color-scheme the user has chosen, I feel
confident, that these are suitable for all kinds of color-blindness (otherwise
the color-scheme is chosen wrongly). But I don't know (yet) which color roles
to use from the color-schemes...

Have fun,
