I've been having this very annoying problem, but I suppose it is not a bug since nobody seems to talk about it...
Everytime a DJ connects to /live (or disconnects) the players like Audacious or Winamp stop playing or they start buffering or make strange sounds. By stopping and starting the stream in the player the problem goes away, but still... I loose lots of listeners everytime...
In this particular case I use IDJC (on Ubuntu) for live stream and IceCast for server.
The bitrate (64kbps) is set to be the same in the DJ console and for AutoDJ in CentovaCast.
