It's okay to call by voice when the phone calls. But text messages, ringtones, music and TV are not played outside.

The receiver and speaker of a mobile phone are two modules. The speaker tube is used for external playback, music and system sound, and the receiver tube is used for talking. There is no sound when listening to text messages, songs or watching TV. The possible reasons are as follows:

Speaker or cable failure, need to go to the factory after-sales inspection to deal with speakers and cables;

There is something wrong with the mobile phone system, which can't drive the speaker, resulting in the speaker can't sound, so it needs to be restored to factory settings or brushed;

Brush into the imperfect third-party system, resulting in the speaker can not sound, it is recommended to brush back to the official system.
