My iphone 4 has no sound coming out of loud speaker. The earpiece works, and the volume bar show also the loudspeaker itself is working as it works with other logic board. What could the problem be on the logic board thanks
Is this a good question?

ur internal sound board might be destroyed, check ur mute button, go into setting, blow into ur headphone jack, if this doesnt work then go to apple store

akshay patel, this could be caused by a malfunctioning headphone jack. If it erroneously sense that headphones are attached, it may open the circuit to the speaker. Do your headphones work?

Hi oldturkey, all the flex and jack are working as it is a test phone that so the fault will be with the logic board, wifi and all that works and the headphone also works the mic is working it only loudspeaker thats not.
