There is no sound in the ringtone, SMS ringtone and MP3 player ... You can hear it on the headset after plugging it in ... Is the sound of the external player broken?

In view of your situation, I suggest that you can judge the situation according to the following methods, which will help you solve the problem:

1. Verify whether there is a mobile phone membrane covering the mobile phone speaker;

2. Please check whether there is more dust in the surrounding environment to cover the speaker;

3. Adjust the sound through the volume adjustment key, whether there is improvement;

4. When doing other operations (such as playing movies, etc. ), whether the situation is the same, if not, I suggest you try other songs;

5. If the earphone can hear the sound, it proves that the related parts of the speaker may be abnormal;

Because we can't see your real machine, we can only give you a preliminary judgment. I suggest you go to the local area as soon as possible to test the related components such as speakers, so as to use them normally in the future.
