I've started getting a loud beep notification when my battery hits 15%. Possibly this happened after an Audio Manager update but I don't see any settings in the app to change it. Previously the notification was silent, I didn't even know it could have a sound! There doesn't seem to be a relevant setting under
Settings -> Sound.
How can I disable this notification sound?
I'm rooted, running 2.2 (TeamWhiskey's NextGen v1).
