No sound during calls, chipped logic board

hello! the new ios is out now (5.1)

but i cant do an update because i need the jailbreak, could you please try that, so that we can see if the issue is because of the software?

(I have the same sound problem)

Try going to settings and then sounds, then turn the volume all the way down with the slide bar after that turn it back up, sounds strange but has worked for me on multiple occassions!!

you have a faulty screen, I had the same problem when i purchased a cheap one on eBay. I could not get any sound during calls and the other person could not hear me either. I put the old cracked screen and everything worked fine. I complained to the seller and got a refund, I brought another one which was a bit more expensive but it worked fine.

its a hit and miss i have found with aftermarket LCD/Digitizer screens some suppliers are cheap but somewhere in the manufacturing process something got screwed up, other times its good.

take a pair of headphones and plug them in to the jack. Make a test call. If you hear audio and can hear the caller then it is the earpiece speaker. Got to ebay and buy a kit with the part, and tools. SHouldnt cost more than about 4$ us. come back to this site and you will find a manual on how to replace the part. pretty easy, took about 30 min

Change the dock connector mic assembly. The apps all work off of the top noise cancelling mic and the calls work off the bottom mic on dock connector. Phone may be stuck in headphone mode.

reset the settings ... worked for me ... hope it helps

hi guys i have the same problem but the funny things is when i used skype or viber or any apps they work fine bur when i try to make call from my sim card i couldtn hear anything please help please

Hai,

I had the same issue with my sisters i-phone, and i read all these forums.As one said i tried software updation but it cudnt help. IF its the prob, then speaker wudnt work at all like wen v play music No sound wud b der. But this case is different. The solution is very very Simple..

Go to the TOP LEFT SIDE OF UR PHONE THERE IS A BUTTON(MUTE BUTTON).. Turn it other way ..if u have a case, open the square shaped box of the case and do it.

The mute button may b turned on accidentlyso jus turn it off and try.

Who else experiencing no sound while on phone calls? Any updates regarding workarounds?
