System/media/audio/ui/bootsound.mp3......well that is what worked on one of my old androids, although I think it must be enabled in kernel perhaps as that does not work on all android devices, in fact, I remember I was running a CM rom, maybe not possible on stock.
That path looks familiar... maybe I shall try it, but I am sure I did last night. Thank you!
## EDIT ##
I tried every conceivable thing:
Created: Bootsound.ogg, bootsound.ogg, Bootsound.mp3, bootsound.mp3
I placed the above in /system/media, /system/media/boot, /system/media/audio, /system/media/audio/ui
I chmod'd 644 to the audio files, I created a new "bootanimation.zip" with the "s Bootsound.ogg" specified in "desc.txt" as the source of the boot chime, and ZIP'd with "-0" (store) attribute when ZIPing it, pushed it back to /system/media/boot and chmod'd it back to 644 and rebooted... NOTHING!
