No voice in a call without the speaker ON

[Tronky]

Hi all

Suddenly my iPhone OTB 1.1.3 has stopped sending voice to the normal speaker, it only send voice to external Speaker so everytime I'm making or receiving a call I have to click on th Speaker icon to hear the other side.

It happened only 2 hours ago and before that I heared a buzzing sound everytime I'm making or receiving a call but I was still able to hear the other side.

Is this a software or hardware problem ?
Anyone has experienced such a thing ?

i had that problem before too with my 1st gen iphone... i did a restore and all was well... though i did jailbreak my phone so i think it had something to do with that and installing certain hacks/tweaks... now if it a hardware problem i would check my warranty information on the apple website

First try "Restore all settings" in Settings on your iPhone.
Solved a similiar problem for me.

I had the same problem but all i did too fix it was plug my headphones into it and take them out. DONE!

This worked for me so far
but the buzzing sound is still there during a call when the other side speaks

Thanks plague

Not working again

I tried a restore this time but it didn't work, more over the installer has gone (

I forgot to tell you that my iPhone is jailbroken

Turned out to be an internal speaker fault
must be changed to get it to work again
