I don't know where the music comes from, but how to turn it off.

There are several ways to turn off music from unknown sources, such as checking the notification bar, checking the application, checking the audio channel, and restarting the mobile phone.

1. Check the notification bar: Check whether there is a notification of music playing in the notification bar. Sometimes, the application will display the notification of music playing in the notification bar, but the user may not realize this. You can try to turn off the notifications of some suspicious applications and see if you can stop playing music.

2. Check the application: Check the application list of the mobile phone to see if there is an application playing music. Some applications may automatically play music in the background without the user's knowledge. You can try to close some suspicious applications and see if you can stop playing music.

3. Check the audio channel: You can try to check the audio channel settings of your mobile phone. On most mobile phones, you can turn off the music temporarily by calling up the volume controller through the volume button on the side or top, and then turning all audio channels to the lowest level.

4. Restart the phone: If the above methods can't solve the problem, you can try to restart the phone, which may solve the problem of playing music unexpectedly.
