Why Does OPPO Phone's Speaker Has No Sound

Fix the OPPO phone speaker with no sound

There could be many reasons that are causing your OPPO smartphone's speaker to stop working. It could be outdated software or a damaged speaker. Proceed to the following paths presented.

Check your sound settings

• For ColorOS 5.0 and above: Go to [Settings] > [Sound & vibration], and under VOLUME, you can separately set the ringer volume, media volume, and alarm volume to the maximum. 

• For ColorOS  3.1 and 3.2: Go to [Settings] > [Sound & Vibration] > [Volume], and then you can separately set the ringer volume and Media volume to the maximum.
  

• For ColorOS 3.0: Go to [Settings] > [Sound & Vibration]  > [Ringtone Adjustment] and then set the ringer to the maximum.

Turn off Do Not Disturb / Quiet Time

Go to [Settings] > [Sound & vibration] > and check if [Do Not Disturb], [Quiet Time], and [Silent mode] option is turned off. If not, toggle the button to turn it off. 

Check the third-party app sound settings

If you don't hear sound only in one particular application, check the app’s sound settings and see if you have set the app sound on mute or turned down the app volume.

Clean the phone speaker

Check if the phone speaker is clogged or dirty, and gently clean the speaker with a clean, soft-bristled brush.

Remove phone case

Ensure nothing is blocking the speaker, such as a phone case or your fingers. The metal phone case can affect the degree of cell phone signal reception. Remove the phone case or screen protector that might block the speaker, then test again. To avoid this issue, we encourage using official smartphone accessories from OPPO.

Check the connected accessories

If your OPPO phone is connected to a headset, make sure it is plugged in firmly.

If a Bluetooth headset is connected, go to [Settings] > [Bluetooth] > under paired devices, check the current headset you are using > tap on the [i] icon > [Unpair] > under Available devices, look for the headset you just disconnected, tap on it > [Pair].

Plug earphones into your phone

Plug in a compatible earphone to your phone and check If you can hear sound through the earphones but not through your phone's speakers; unplug the earphones and test again.

Perform Component Check / Common Problems Detection

Check for speaker errors using Common Problems Detection in Phone Manager. If detection results in Speaker return Error or Not Detected, contact the OPPO Support Team or take your phone to the service center. 

• For ColorOS 12 and above: Go to [Tools] folder on your home screen > [Phone manager] > [Tools] > [Diagnostics]. Select [Audio] and disable other components. Tap [Run diagnostics] and follow the on-screen instructions to check if your speaker works properly.
  

• For ColorOS 11 to 11.3: Go to [Tools] folder on your home screen, then [Phone Manager] > [Diagnostics] > [Continue]. Select [Audio] and disable other components. Tap [Run diagnostics] and follow the on-screen instructions to check if your speaker works properly.

Restart phone

Press and hold the Power and Volume Up buttons for at least eight seconds or until you see the OPPO logo. Or press and hold the Power button and tap or slide [Restart] to restart the phone.

Update the phone software

* DO NOT root your phone yourself, for that might affect the phone’s system performance, and the warranty service will be terminated.

Other issues

There are other possible causes for the speaker issue:

• If you cannot hear a specific person's voice clearly, it might be his/ her phone's issue. 

• For network issues, consult with your network operator.

 

If the abovementioned steps did not fix your concern, prepare your warranty card and contact your nearest OPPO Customer Service, you can also contact OPPO Support so we can help and assist you further with your concern. Depending on your region, you may check if you need to book an appointment before visiting your local Service Center.
