Reinstall the sound card driver, and set the earphone as the default playback device in the control panel
There are many reasons why the earphone is plugged in or played out. You can first rule out the earphone problem, earphone plug problem and mobile phone jack problem. It may be that your earphone plug is not compatible with the earphone hole of your mobile phone. If it still cannot be solved, it may be that the circuit is damaged due to the internal damage of the mobile phone. Then let me tell you what to do. It's actually quite simple.
1
It should be caused by the failure of the microswitch in the earphone jack, that is, the earphone has been pulled out, but the switch has not been turned off in time. You can try unplugging the headset several times quickly to see if you can make the headset logo disappear, or restart your phone.
2
If the mobile phone is allowed to open the back cover, you can take the back cover apart and take out the battery of the mobile phone, so that the battery of the mobile phone is separated from the mobile phone for about 1 minutes. You can put the battery back in 1 minutes, then press and hold the power button to restart the phone. We must wait patiently here. Don't touch your mobile phone casually. After the phone is turned on, don't move the phone casually at this time, so that the phone can fully respond. Then plug in the earphone. Under normal circumstances, according to my method, it can be repaired.

It may be caused by the incompatibility between the earphone and the mobile phone. If your earphone is equipped with a headset, check whether it is incompatible due to four or three plugs. You can try to buy an earphone adapter.

There are several ways to try: 1. Try to play other music. 2. Turn up the volume of the media. 3. Try using the original headset.
5
If it still doesn't work, it is possible that the jack circuit in the mobile phone was damaged after the phone crashed, so it can only be returned to the factory for repair.

why do Huawei headphones plug in or play music outside?
If your mobile phone is plugged into a wired earphone and the sound is still playing out, you can check the operation by the following methods:
First, if you use a non-standard one-to-many wire or the earphone patch cord may be incompatible with the mobile phone, the earphone will not be recognized;
it is recommended that you use the standard charging cable or earphone patch cord.
2. If you are using a TYPE-C interface earphone (charging interface), the troubleshooting steps are as follows:
1. Please try plugging and unplugging the earphone again to ensure that it is completely plugged in. (If protective case or case is used, please make sure it is fully inserted)
2. It is recommended to replace other mobile phones or try to connect the TYPE-C interface headphones. After cross-verification, if only your headphones can't be used, it may be that there is something wrong with your headphones. If only your mobile phone can't recognize the headset, it is recommended to back up important data (WeChat /QQ and other applications need to be backed up separately) and take the headset, mobile phone and purchase certificate to Huawei Customer Service Center for testing.
3. If you are using a 3.5mm interface earphone (small round hole), the troubleshooting steps are as follows:
1. Please try to plug and unplug the earphone again to ensure that it is completely inserted. (If you use a protective case or case, please ensure that it is fully inserted)
2. If you use a three-party earphone (not Huawei earphone), please consult the seller to confirm whether the earphone is American CTIA interface (LRGM line sequence). Huawei mobile phones do not support national OMTP interface (LRMG line sequence) headphones.
3. if you use a TYPE-C to 3.5mm adapter, please make sure that the adapter is normal and all connectors are fully inserted.
if you still can't get back to normal after the above operations, it is recommended to back up important data (WeChat /QQ and other applications need to be backed up separately) and take headphones, adapters, mobile phones and purchase vouchers to Huawei Customer Service Center for testing and processing.
Warm reminder: When using the earphone, the ringing of the incoming call and the alarm clock will be played from the speaker and the earphone at the same time, which is normal.
