Hello friends.
I found a problem this morning with my cellphone, Media Mode does not sound while watching movies or playing games
- The cellphone that rings, the microphone, and the speaker are good and work correctly.
- I tried it with disable headphone (enable sound) software, it returns to normal for a short time and locks again.
- I reset the cellphone to a hard drive and also found a virus, but the problem was not solved.
- I downloaded all my software from Google Play, This problem happened during a promotional video game today, I also deleted that software, it didn't matter

What should I do? Does anyone find a solution?
Please guide if you have a solution
