Why is there no sound on the mobile phone?

1. Check the sound of the mobile phone: If there is still no sound after the background running software is turned off, please check the sound of other software, such as playing music to see if there is any sound. If there is sound, the speaker is normal. If not, it may be a hardware failure.

2. Shut down and restart the mobile phone: When there is no sound in the WeChat voice of the mobile phone, this situation may probably be caused by the abnormality of the mobile phone system. We can try to shut down and restart, and sometimes we can solve the problem that WeChat voice has no sound.

3. Check whether the mobile phone enters earphone mode: I believe that many friends may have no sound when listening to music with headphones. This may be caused by the system entering headset mode, so there will be no sound when hearing WeChat voice. At this time, you can try to plug in the headphone cable, listen to whether the headphone mode exits, and return to normal after playing the sound.
