Sony Xperia XA2 [H4133] media output problem

On this device I have a problem with the release media.
no sound comes out of the device with or without a helmet with the following applications: music player, newpipe, radiodroid, fennec, as well as browser.
How can I fix this?

I spent the phone with the update “murena one,” or the media problem still persists with no sound output.

This type of equipment is usually proposed for the American continent and its neighbours, there would be a solution to fix the problem?

Thank you, for a concrete answer.
