What I've done, Installed a Sound Binary from Boot Animation Changer, Renamed the sound file to Android_audio.mp3, And placed the file in /System/Media/Audio/Ui, With the Permissions Rw-rw-rw
I checked the Default.xml file, to see if it points to the file.
<BootAnimation animation="/system/customize/resource/htc_bootanimation.zip" audio="/system/customize/resource/android_audio.mp3" />
So i placed the Sound file into System/customise/resource/ and yet still no sound,
I suppose I'm a noob, so if anyone can help me out that would be great, thanks.
