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.


It looks like to be the same problem as reported here: No sound and video stutters (#4500) · Issues · e / Backlog · GitLab
The proposed solution is explained there (need to do a sideload in recovery) : No sound out of loudspeaker and headphones since upgrade from 16 to 17.1 (#1919) · Issues · LineageOS / issues / android · GitLab

I’m thinking to perform an upgrade of my XA2 but i’m worried about this issue, I would be interested to have your feedback it’s if it’s working fine after it. I hope it will.
