We've had a few reports of music/media problems with the meta7 viewer, but it might also be a problem on other viewers as well.

#1 Make sure you have turned on your media/music stream in your Preferences - Audio & Video

#2 Make sure you have your speakers on ?! haha

#3 make sure you downloaded the latest QuickTime !!! visit apple.com/QuickTime to download it. Most Music or Media missing problems get resolved by doing that.

#4 Enjoy the music/media or if you still have problems, file a support ticket on support.meta7.com
