Sansa Clip Firmware 01.01.35 & 02.01.35 Release

Something that has really decreased the value of my Sansa clip with this update is the decrease in sound, this became very apparently right from the beginning after I’ve updated it. So the question, really, is, what can I do about it?

Is there any setting I can go on and mixture with (I have it as high as it goes right now) or do I need to remove the latest update and try the previous? If so - where do I do that and how do I do that? Sound is the most important to me.
