### Remarks

When playing audio from a URL, the number of audio tracks is not known in advance.  It is up to the user to specify the number of controlled audio tracks through [VideoPlayer.controlledAudioTrackCount](/engine/6000.0/script-reference/unityengine/video/videoplayer/controlledaudiotrackcount.md).  Other tracks will be ignored and silenced.  In this scenario, [VideoPlayer.audioTrackCount](/engine/6000.0/script-reference/unityengine/video/videoplayer/audiotrackcount.md) will be set to the actual number of tracks during playback, after preparation is complete.
