Try clicking on audio, click full processing mode, and click volume and try turning it up that way and see what it does.

but al the other parts had volume and i noticed part 0 and 1 does have sound but its just cracking sounds

update, the AVI itself has sounds and wen i convert them to AMV it goes all weird some of it has sound some of it doesn't and when i try to fast forward it on pc it freezes for a bit then will fast forward
