Wechat voice call can't hear clearly what's going on

The problem with setting should be that WeChat has a setting option, and there is a general option in the setting. Click the enable option, then cancel the high-speed recording mode, and then you can make it clear when you speak.

You may not have turned on the speaker function in WeChat, so you can't hear the sound without the speaker (the sound is played in the receiver). Select General-Turn on phone mode. Wechat sent by the other party didn't speak during recording, or there was something wrong with the other party's microphone, so there was no sound. Maybe the other party didn't turn on the recording function in the software permission, so there was no sound! Just open it in the following way.
