Apologize if this has already been adressed. Never had this happen at home, only at work the last week. Happens at least once a day. While listening to the stream on Windows Media Player suddenly in the middle of a track, the sound dies, although the player is still playing and then suddenly there is a soft track that starts out with a fast violin piece. The only way to fix this is if I stop the player and press the play button again, then the real track is back to playing again. What is causing this?
