Well i found the problem. It seems that one of the 3 widgets i sent her had a volume bar, she tried it and when closed it, the sound bar was at it's lowest position, so when she opened any other widget player, she had no sound. Once i re-opened the widget with the sound bar and put the volume up, everything worked fine. It seems like the widgets are like co-dependant or something. Anyways, thought i would let people know so if it happens to someone else, the answer is here.
You learn everyday.
