COMMON< Audio implementation issue

i set mouse over animations for event driven sound files…
play once

i test on computer = works fine
but when i upload onto the net there is a delay between when the sound plays and when the user hovers his/her mouse over it

ive even noticed other flash websites doing this, and im sure its not my computer because im running a beast atm…

any tips/ideas

ive even seen V4 of 2advanced have this issue -_- :hurt:
