problem with sound loop in audio source component

hi

i have a audio source in scene . it have a 5 second raining sound . in windows music players it repeat very well BUT in unity it have a pause (0.5 second) before it start playing again !!!

<<< i checked loop checkbox >>>

what should i do ? how can i repeat it immediately after it finish ?

i want play it like it raining , without pause after it finish !

When you play your sound clip (not on loop), do you hear sound right away or does it have a low point at the beginning.?
If the file does have a low point (silent beginning), the loop is working properly and your problem is with the file itself. You will have to alter the audio file if this is the case.

Cheers!
