[Description] When users try to play a youtube video, dvd or other media, they hear no sound. This is a combination of issues usually. Sound is controlled by the computer itself, the speakers in the room and the application (e.g. youtube). [Resolution or Workaround] 1. Make sure that the mute is off of the computer. The speaker icon on the system tray should show just a speaker, not a speaker with a red X. 2. Make sure that the volume is up on the application (e.g. youtube, DVD player, windows media). 3. At this point, check to see if you can get sound out of a YouTube video (any). 4. If you cannot, make sure the physical speakers are turned up. Different rooms have different controls. Check the room quick card but generally: a. there is a speaker on the front of the cart with a volume control b. there are volume controls on the touch controller on the cart or wall. [Issue] 
There is no volume coming from the media cart.
