Hello.
First off, I just want to say that I read all related questions to my problem on this forum already, but I think my scenario might be a different situation. (Maybe or maybe not)
On a SharePoint 2010 page, a user has inserted a Media Web Part, and changed the media to a video stored in a video library on the same site. The video plays on the page, but with no audio. The weird thing about this is that another Media Web Part with a different video was inserted a year ago on the same page, and this works fine for the user. As a note, both videos are a .wmv extension.
Now, both videos work fine for me, and the user and I are both using IE8. Something that differs between us is that the user is running windows XP, but I'm running windows 7. I checked with a couple of my colleagues and noticed it worked for those using windows 7, but not windows XP.
Does anyone know why this could be happening? Thanks.
