I fixed my speaker problem in 5 mins

Hey There! What I did was went to radio shack and got some caned air and went home opened up everything I possibly could on my comp and sprayed what I could down. I took the battery out while I was doing so. I than put some air in the speakers. Turned the comp on and wala!!!! I now have sound again... I thought I would try for the heck of it and it worked.... Hope This is helpful...
