Speaker issue on Blackberry Storm

I just updated the software on my Blackberry Storm.

The speaker on the device does not produce a good sound (it sounds like a broken speaker?).

The ring tones sound bad, also when I play radio, music or video on the device.

I tried to change the ringer set up (volume etc), it did not help improve the sound that comes out of the device's speaker.

I did nothing else prior to this situation.


Is this problem related to the software upgrade?

Does anybody have any solution to this problem. Thanks.
