My problem with the Xperia Xa is that when I call the other person I do not hear. I have tried to repair software and have reviewed the sound and call settings and turn on creating audio with no result.

Hi @Cacharra, I am very sorry to hear about that.
Have you also tried to see if the earspeaker works in the Diagnostics test? In order to try the test, go to Settings > About phone > Diagnostics > Earspeaker.
If it still persists after a software repair then my recommendation would be to have your device sent to an authorized service center so that a technician may examine it for you. In order to do so, I advice that you get in touch with your Local support team and have them assist you, as they are well informed when it comes to local service routines, warranty terms and consumer laws.
Let me know how it went!
