No Sound from DS Lite

[ChrisRX]

I have no sound coming from my DS Lite. Well that's not exactly true, if I hold the DS right up against my ear I can just make out some sound, the same happens if I plug headphones in that I can just about hear some noise through my headphones.

As a lover of rhythm games this is obviously disappointing :P
I wonder if anyone knows anything about that this, maybe a blown fuse or something like that?
