my iphone 4 speaker is not working I already tested the sound chip by doing a bridge between the two pins in the dock and an aux cable connected to a random speaker and by testing the speaker of the iphone by doing a bridge between it and an ipod/or a computer and it did work.
I also did a bridge between the iphone and its speaker but with no results

Hello Marco, it sounds like your device has a faulty charge port assembly which is causing your problem. That or your headphone jack flex cable is damaged and causing the speaker to not function. Just to be sure, I would replace both cables and check your work.
Heres some guides to help
Hope this helps, Good luck mate!
