'Bump Fix' was a miracle for me. I just realised today that my speakers are not working after missed many calls as it was not ringing. I just played back some songs and made sure it was a speaker issue and found this thread.
But I was not sure if this was just a joke or how hard I must bump. I just banged it on my sofa and did not work. Then just shake bit hard and I noticed that I heard something ( a part of song). Finally I gave a good 'Tap' on the speaker and it worked. Here are my steps and hope some one will be helped.
1) Play any music file
2) Turn the backside of the phone
3) Spot the speaker (left to the camera)
4) Use your thumb and middle finger (or any fingers to make it as a Carom shot) and hit hard.
5) Its ok to hit hard as long as you use your fingers. But make sure you do not damage the camera.
6) After few (for me 2 shots) shots, you will get your speaker back.
This is a good try before you take any hasty nasty actions like un/reinstall programs/drivers/ROM or do physical repairs.
Cheers !!!
