How to Fix Xiaomi Phone Earpiece (Top Speaker) Low or No Sound

Fix xiaomi earpiece no sound and redmi call speaker low. Solve poco earpiece fix for xiaomi top speaker issue and xiaomi call volume low fix.

If you can't hear the other person clearly during phone calls on your Xiaomi phone, the earpiece (small speaker at the top) may need troubleshooting.

Step 1: Raise Call Volume

During an active call, press the Volume Up button to maximum. Call volume is separate from media and ringtone volume.

Step 2: Check Do Not Disturb Settings

Go to Settings > Sound > Do Not Disturb — if enabled, some DND configurations can suppress call audio. Disable DND temporarily.

Step 3: Clean the Earpiece Grille

The earpiece grille (thin slit at top of screen) collects dust. Use a dry soft brush to clean it carefully. Avoid inserting pins which could damage the speaker mesh.

Step 4: Check Accessibility Settings

Go to Settings > Additional Settings > Accessibility > Hearing — ensure no audio settings are reducing call volume unexpectedly (e.g., mono audio, volume balancing).

Step 5: Disable Noise Cancellation

In some cases, the secondary microphone used for noise cancellation can interfere with earpiece audio. Go to Settings > Sound and disable active noise cancellation (if available).

Step 6: Run Earpiece Hardware Test

Dial *#*#64663#*#* → select Earpiece or Receiver test. This plays audio directly through the earpiece so you can confirm hardware functionality.

Step 7: Test in a Call App vs Built-in Dialer

If the issue only occurs in a specific app (e.g., WhatsApp calls vs regular calls), it's an app-level setting issue. Check the app's in-call audio settings.

Step 8: Service Center

If the hardware test confirms no earpiece audio, the speaker component needs replacement ($15–$30 at Xiaomi service center).
