Niner since 2009
I am unable to hear the sound when this video plays in silverlight. I have the latest silverlight plugin installed. Only the video plays fine.
Update: It seems that only a few silverlight video has got this problem. For eg. I have no problem with this video (https://channel9.msdn.com/posts/matthijs/Scott-Guthrie-Visual-Studio-2010-and-NET-Framework-40/).
Everything is fine with this video.
I am using IE 8.0 to access this video from India.
