As the title says, my main microphone don't work in camera recording, in calls or in sound recorder. I did a hardware test using Z-DeviceTest and it says that my microphone's 1 channel (see attached screenshot), but Xperia U has two microphones. Is it relevant? How can I fix it?

Note: I've got CM11 Build 12 and no one else have reported this issue, I've reinstalled the ROM and Kernel from Stock ICS and it's still not working.

DEVICE: Sony Xperia U
ROM: Xperia STE Team CyanogenMod 11 Build 12
VERSION: KitKat 4.4.4
E/S Governor: SIO

Finally I relocked the bootloader so I recovered my warranty and gave it to the SAT.
It was a hardware problem!
