Motorola :: Atrix Plays Music Too Fast

I recently purchased a non-us atrix with Bell Mobility.Everything works well except when I tried loading it with music and playing them.The play speed is too fast so it sounds wierd.I tried using the OEM player and a few other ones (Win Amp, Power Amo) but the results are the same.Si it does not appear to be a problem with the player.In addition, when I played a video (MP4), the video plays normally, but the audio sounds similarly wierd (i.e. with high pitch as if it is played at high speed).
