Default BT problem after upgrading to 4.4.2

Hi.

After upgrading to 4.4.2 I got some problem with BT handsfree. ( Mygig )
I can hear the other party, but they can't hear me.
I downgraded back to 4.2 and the problem was solved.
Upgraded back to 4.4.2 and the problem is here again.

Model D955 and rooted.

Thanks !
