Some of the audio streams (especially the low bandwidth streams) can be delayed. We've seen delays of more than 100 seconds. This delay results in pictures that are out of sync with the music. If you are using an audio stream with a delay, you can synchronize the audio and the image stream here. To synchronize the audio stream with the image stream, click 'Sync' at the moment when you hear the song song name begin. 'Clear' eliminates any sync delay. If the song has already started, just wait for the next song.
