Answer to: The cause of iPad speaker to break down?This info put me on the right track. I blew air into the dock and got some sound for a second. However it stopped completely after repeated attempts. Finally after replacing the dock with no sound still, I blew into speaker holes and some sound! Not consistent though. However when I sucked on the air holes of the speaker area on the case, I got sound, consistent sound. It lasted only as long as I applied suction. I'm thinking it's the actual speaker or some connection related to it in my case. Hope this helps some with similar symptoms.
