Tried to set an alarm on the default clock app on the Legend. To my surprise, it never went off when it was supposed to. When I tested it I was quite shocked to find that the built-in/default sounds wouldn't play. When it put I enabled the vibrate checkbox, it began to vibrate at the set time but there was no sound. So I downloaded an alarm app from the droid marketplace and it worked fine. Even the default Legend sounds were working in the app. When I went back to the built-in alarm, the sounds started playing normally. Not sure what could've caused this. Could it have something to do with the task-killer?
