I've downloaded some Java games to play on the Nokia 5130 Xpress Music. I can play them perfectly, but I can't hear any sound. The volume's up, application tones - on, profile - general. Can't hear the sounds, though. How do I enable the sound thing? Please help!

To check if there is some error in your phone's system, why don't u try jar applications like kd player, guitar hero etc, they are supposed to produce sound if your profile settings allow. If u still don't get the sound in these app, then there ought to be some problem with ur phone's OS or its java version. If its due to bad java, Updating ur nokia software in nokia website would be the solution
