I am using the Acer Iconia Tab A500 and having some problem to play the movies in that. Whenever I play the movies then I found that there is no sound in that. I can only get the videos. I am not getting that in the headphone as well so there is no problem with the speakers. So can you please tell me that what I should do in order to get this problem solved? Please reply fast s I need to get it solved as soon as possible. Thank you.
