Why is my speaker not working

Please help me. After changing the backcover the speaker stopped working.

I replaced the it with a new one but it didn't work. The exchange of the audio jack flex cable unit didn't help me either.

What did i miss? What can i do to solve this probem? Really everything works fine but the speaker..

Answer this question I have this problem too

Is this a good question?

Did you check the hardware mute switch status ?


Yes of course.. But i dont think that it's a problem with the mute switch because normally music can be listened to while the mute switch is 'on'...


Then you have to replace audio codec


how can i replace it? It's soldered to the mainboard, isn't it? And where can i order the audio codec/another mainboard? the only link i've found is around 450 USD and thats way too much. Anyway, replacing the mainboard won't work or am i wrong?

Sometimes the grill for the aftermarket backs are not good i suggest just poke the 6 holes with a needle on the bottom right you should get some sound.

Before you do any board repair try replacing the speakers and charging port first again
