What happens when packets are dropped in UDP? A bit of audio corruption. What happens when packets are dropped in TCP? A hard-to-predict amount of delay. And retransmission of audio data that you might just throw out anyway. (There are alternatives to discarding the data that should have already been heard, like temporal compression, but that's hard to do right, too.)
