Adding boot sound to Froyo 2.2 Droid

Question

I have been attempting to add sound on boot to run with the boot animation on a droid running Froyo 2.2 ROM.

This is what I have tried this far:

Added to init.rc

###Bootsound - Safe to Delete: Start ###

service bootsound /system/bin/bootsound
        user media
        group audio
        disabled
        oneshot

on property:init.svc.bootanim=running   # to correct timing
        start bootsound

on property:dev.bootcomplete=1
        stop bootsound
### Bootsound - Safe to Delete: End ###

Created bootsound in /system/bin

#!/system/bin/sh
#bootsound - plays a sound at boot

bprop=/system/build.prop
grepprop() { x=`grep "^$1=" $bprop | head -n 1`; echo $x | cut -d = -f 2; }

play=`grepprop "ro.config.play.bootsound"`

if [ "$play" = "1" ]; then
        stagefright -a -o /system/media/android_audio.mp3
fi
exit 0

Added to build.prop

### Safe to Delete: Start ###
ro.config.play.bootsound=1
### Safe to Delete: End ###

And of course added the android_audio.mp3 file to /system/media

No luck, can anyone spot what I may have missed?

Thanks
