What to do if the Xiaomi phone speaker has no sound?

Question

Accepted Answer

If the Xiaomi phone speaker has no sound, please refer to the following information:
1. The phone may be in Silent mode or Do Not Disturb mode, so please check whether these modes are enabled and turn them off before testing the speaker.
2. The phone can be connected to a Bluetooth headset, which redirects the sound, so please turn off Bluetooth or disconnect the Bluetooth headset and then test the speaker again.
3. The phone can mistakenly detect a wired headset due to a faulty headphone jack, so if no wired headset is connected, but the Status bar shows a headset icon, try cleaning the headphone port and test again.
4. There can be a hardware issue with the speaker, so you can open the dialer and enter * # * # 6484 # * # * to enter CIT (Hardware Test), then select the speaker test to check whether it works properly.
5. The system software can have bugs affecting sound output, so please upgrade the phone to the latest OS version.
6. If none of the above steps restore sound, it is recommended to contact after-sales service for professional inspection and repair.
