Google music volume resets to max after each song

problem is as per strapline.
I'm on XXDLJ4 and want to use Google music player with noozxoide 2.0.1.7
Found this similar thread but it is unanswered....

if I go to settings>sound and change to musicfx the volume remains stable

anyone else got this, or even better, got a solution?
