After updating to 4.1.2, I'm happy except for one frustrating thing. Everything that results in a notification being posted in the pull-down list, now results in an audible notification. The sound appears to be the facebook-pop, but its so frustrating having it happen with every single notification of any kind! Has anyone else seen this? I can't find anywhere to turn it off and am getting a bit frustrated - now I find that if I connect my bluetooth speaker and try to listen to Pandora, it mutes the music and makes the pop sound through the speaker every single time too! Grrr!
