I love my little HTC Android handset, but one thing that does bug me, despite HTC's moniker of "Quietly Brilliant" is that every time you turn the handset on it plays a loud and annoying startup sound which cannot be disabled. So, to combat this I have put together a small Android App which silences this noisy start.
The app is fairly simple. It switches the ringer and media volumes to silent when you shut the handset down, and restores them again when you switch the handset back on and bootup has completed.
If you wish to install the app you can find the apk file here. In order to install it you will need to ensure that you have "Unknown sources" option enabled which you will find in Settings -> Applications.
I have only tested it on my own HTC Wildfire S so any feedback from other device users would be greatly appreciated.
Note : Doesn't currently seem to work correctly with Fast Boot enabled.
