Why don't I have any sound during a mobile call (S4 Active)?

AC Question

No sound during mobile call (s4 active)

I tried everything, i changed the mic and speaker.It works only with bluetooth headphones during calls. I downloaded an app called soundabout and now my call works but only with internet call like facebook and whatsapp so that means my mic is fine. But when i make a mobile call I dont hear anything and neither does the other person.

Updated my s4 active for lollipop
How could not get from the downloaded firmware phone, the drive of Samsung and Odin .
I could not download from Cybers . They are Prohibit downloads. I tried to corrupt did not so right, made ​​three shipments of 125 Utts (30 usd ) Unitel generating 1,500 mega bytes.
This is because I had the bonus of 100 %. Otherwise they would be 750 mb.
The firmware downloaded is 1.3 gb.
I succeeded in the process, but what led me to invest was that I could recover the sound at the time of the calls so far still is maintained with this problem.
So far only had the sound once.
