SYMPTOMS
When you watch Live TV in Microsoft Windows XP Media Center Edition 2005, you may not always be able to hear the audio.



CAUSE
In an attempt to provide the highest quality audio experience, Media Center will always play any AC3 (Dolby Digital 5.1) audio stream that is present in the broadcast. Some stations may broadcast the required primary stereo stream, and some may also broadcast the optional AC3 (Dolby Digital 5.1) audio stream. If Media Center detects that an AC3 stream is available in the broadcast, Media Center will select that available stream. Some broadcasters may occasionally broadcast empty or &quot;muted&quot; AC3 streams. Therefore, if a broadcast contains an AC3 stream, but no audio data is present, Media Center will have no sound for that specific channel.



MORE INFORMATION
Currently, Windows XP Media Center Edition 2005 does not have an option to force the use of the primary audio stream when a muted AC3 stream is present. You may choose to contact your broadcaster and report the muted AC3 stream.
