Akpome,

If the sound file is being played more than once, there is a good chance 
that this is already happening.  At one point, our production system had 
100 calls in queue.  Each call had pre-queue announcements from the 
dialplan, native MOH, and in-queue announcements.  I ran iostat on the 
system, and there was no disk read activity at all.  I believe this can 
be accounted for by Linux's file caching.

If you run iostat on your system and see read activity, give this a try:

1) Set up a RAM disk
2) Build an init-script that copies your sound files from the hard disk 
to the RAM disk on boot
3) Configure Asterisk to play the files from the RAM disk
