Mobile phone wechat can't hear voice. What happened?

If you use a Huawei mobile phone, there is no sound when the WeChat voice message is played. If the volume adjustment is ineffective, please refer to the following scheme for troubleshooting:

1. Check whether the intelligent key device is plugged into the headphone jack.

If a intelligent key equipment (such as 360 intelligent key, Xiaomi intelligent key, ICBC U shield, etc. ) has been plugged into the mobile phone, please unplug the smart key device and try again.

2. Check whether the phone is connected to other audio devices.

If a Bluetooth device or other audio device is connected to the phone, please disconnect or remove the audio device and try again.

3. Check whether the mobile phone has a screen projection.

When a mobile phone projects a screen, the priority of sound output from high to low is: Bluetooth device, wired earphone, large screen, adapter and mobile phone. Please check whether the projection device is mute.

4. Check whether there is a new version of the application.

Please enter the Huawei application market to see if there is a new version of WeChat. Please try to upgrade your application to the latest version.
