Problems: Hoarse, Saving Project and Clip Automations..

[FinoAttack-Tuuce]

Hi everybody,

I have a few questions..I'm new at Ableton Live 5..

My soundcard is M-Audio Audiophile 24/96 USB
I am working on a p4 Intel 1Ghz PC

First Question;
- There is a general hoarse problem..When I listen an audio sample from the selected directory on the left panel, everything is fine. But when I drag & drop it to the simpler the sound changes and as a result of this; there is a general hoarse problem in my projects because of the change of my audio sounds when I use them on Ableton Live..Is it normal?

Second Question;
- On the project that I am working, when I select all of my clips and drag & drop them to the selected folder in the directory at the left panel it saves the project. But, the problem is, when I re-open the project I hear that some sounds are changed (for example my two hihats and a kick which I made using the operator are changed and there is no way that a hihat become a synth-like sound? or a kick?) So I tried the same saving method a couple of times and guess what? every time I save different sounds are changing when I re-open it..Is it a joke? Am I doing something wrong? Or am I missing something? I don't understand..

Third Question;
- Clips, yes, the precious clips..Is there a way to save a clip with its fx, instruments-plug-ins and the automations that are on all of them? How can I? or can I? How can I write automation on a clip by the way???

Thank you for your interest..
