No sound during calls

[eagleflyfree92]

So I know this problem has come up before. I've been researching threads but have had no luck fixing my problem.
The problem is, there is no sound during calls. Not for me or the person on the other side.
The "Call Connect" sound works. It bleeps when the phone connects but there's no ringing or anything like that.
I don't even get the "Please enter your password" dialog when dialing voicemail

I've got the AT&T i337 on OC3 rooted.
I have tried multiple Roms including flashing back to stock.
I have tried removing the Sim Card, SD card, battery and putting it all back.
Re-flashing the modem does nothing.
Whether I turn on or off speaker phone there's no change.

Although I have not done Sim card tests to see if it's the sim card or not.

But any help is appreciated

Update:
I flashed Aurora S6 with all the files I'd need to.
I then dialed my Voice mail and pressed the record button. Apparently the signal Is coming through. But it is not being relayed to the speaker as well as my voice is not being sent out. Does anyone know why this would happen? Or if there are any files that could be corrupted?

Thanks

I have fixed my problem. It was a hardware issue.
There is an Audio chip in the motherboard that is dedicated to calls.

The above link shows where the chip is. I read that if you place a piece of paper or something like that to put a bit of pressure on it, it may help with the problem
Luckily it worked for me.

Do this at your own risk.
I completely cracked the casing trying to get it open.
