Did you try turning off the phone and taking out the battery for at least 5 min? Also, try a master reset? If that doesn't work, contact Nokia care center.

thanks for the compliment. anyway, one example of my downloaded game is texttwist. even the default snake EX doesn't have sound.

Are the games you're downloading specifically for you phone? That might be the problem.

2nd time ever I've heard/seen someone by the name Xanthe...cool name.

i've been downloading games for my n6630, i'm kinda wondering why there is no sound whenever i use the said games. i have set the music/sound mode to "ON" but,sad to say, no sound came from my fone. but as for other apps like MP3, sound is ok. please help.
