Audio keyframes getting moved back to zero

[Nick Lear]

I'm finding in this beta that where I've keyframed audio, any keyframe that isn't at zero dB gets moved there. Quite a bad one as that's a fair bit of work undone. I'm also then finding tht the keyframes won't move down at all some of the time.
