Why Xiaomi has suddenly lost sound – and how to fix it

You've played a video on the Xiaomi Redmi Note 12 or POCO X5 Pro, but instead of music, silence? Or calls come and you can't hear the other person? The problem with sound on Xiaomi smartphones is more common than it seems. 80 percent of the time, software failures are to blame, not speaker breakdowns. But how do you tell one from the other, and what do you do first?

This article will help you diagnose the reason for your Xiaomi silence in 3 minutes.

• 🔊 Basic checks – what to do before visiting the service center
• 📱 Hidden settings MIUI that turn off sound without you knowing
• 🔧 Hardware malfunctions - when repairs are not necessary
• 📊 Table of symptoms for accurate diagnosis

So don't rush your phone into the workshop, and half the time, the sound comes back from simple manipulations, and let's start with the obvious.

1. Checking basic settings: 5 steps before panic

Yes, it sounds trivial, but 30 percent of the "no sound" calls to the service are solved at this point.

Make sure the volume is not at a minimum (volume up/down buttons)

Check if the "Do Not Disturb" or "No Sound" mode is activated

Turn off Bluetooth – it may be the sound goes to the headphones

Restart your phone (hold the power button for 10 seconds)

Try playing the sound through another app (like YouTube after the player)-->

Pay special attention to Do Not Disturb mode, which in MIUI 14+ can be activated automatically on a schedule or when connected to a specific Wi-Fi network, to check:

1. Open Settings → Sound and vibration → Do not disturb
2. Check out Automatic Rules – There May Be Hidden Triggers
3. Turn off the Schedule option if it is active

Another pitfall is sound profiles. Some Xiaomi firmware has a separate "Meeting" or "Sleep" profile that mutes all notifications. Switch to "General" in the Settings menu → Sound → Sound profiles.

💡

If the sound is gone after the MIUI update, try rolling back the firmware through Settings → About Phone → System Update → Three Dots → Select the service pack. Download the previous version from the official Xiaomi website.

2. Software failures: when the phone "deafens" for no reason

If the basic settings are fine, but there's no sound, it's the software that's to blame.

🔹 Resetting of sound settings

Sometimes the sound parameters get lost after updating or installing applications, and you can return them to factory values like this:

1. Go to Settings → System and device → Resetting settings
2. Select Resetting Sound and Vibration Settings
3. Confirm the action and restart the phone

🔹 Cleaning up media services cache

The MIUI audio services are com.android.media and com.miui.player, and their cache can clog and block playback.

1. Open Settings → Applications → Application Management
2. Click on three points → Show system
3. Find Media Storage and Music, clear cache and data

🔹 Safe mode for diagnosis

If the sound is running in safe mode, it's the third-party app's fault.

1. Hold the power button until the turn off menu appears
2. Press and hold Power Disconnect → Safe Mode
3. Check the sound. If it comes up, delete the apps one at a time, starting with the last ones installed.

First time.

2-3 times a year

Constantly, once a month.

Never had such a problem.-->

3. Hardware problems: when without repairs can not do

If none of the software methods worked, it's the hardware.

• 🔊 The sound is only lost in the speaker (it works in the headphones)
• 📵 Wheezing, cracking, or distortions appear when reproduced
• 💧 The phone fell into the water or was subjected to severe vibrations.
• 🔧 Sound is missing after screen or battery replacement

The most vulnerable components in Xiaomi:

Critical information: On Xiaomi 12T and Redmi Note 11 Pro+ models, Qualcomm’s WCD9385 audio codec often fails. It costs 4,000–5,500 ₽ to replace it, but simple flashing through EDL- mode helps in 20% of cases.

⚠️ Warning: If the sound is gone after the phone falls, don't shake it or knock on the body, it could permanently tear off the speaker plume or damage the soldering of the audio codec. It's better to carry it to the service right away.

4. Specific problems of Xiaomi models

Some Xiaomi smartphone lines have unique sound bugs, and here are the most common ones:

📱 Redmi Note 10/11 Series: The Problem with Quiet Mode

There's a bug on these models where the phone spontaneously goes into Quiet mode.

1. Open the notification panel and check the sound icon
2. If it is gray, touch it and select Sound or Vibration.
3. Turn off the option Automatic Sound Control in Settings → Sound

📱 POCO F3/F4/F5: Failure after upgrade to MIUI 14

These devices, after the upgrade, lose the sound in the games and videos.

1. Install an alternative launcher (e.g. Nova Launcher)
2. Open Settings → Applications → Permissions Management → Autorun
3. Enable Autoplay for Media Player and Google Play Music

📱 Xiaomi 12/13 Series: Conflict with Dolby Atmos

On flagships, the sound may disappear due to a bug in Dolby Atmos.

1. Go to Settings → Sound → Sound quality and effects
2. Turn off Dolby Atmos and restart your phone
3. If you have a sound, update the Dolby app to Google Play.

5. Advanced diagnostics: commands and engineering menu

If the standard methods didn't work, it's time to dig deeper.

🔧 Test of speakers through engineering menu

Enter the phone code in the application:

##4636##

Go to Audio and run the tests. If there's a red cross burning next to the Speaker or Earpiece, the speaker is faulty.

🔧 Verification of Logical Partitions with ADB

For power users: connect your phone to your PC and do:

adb shell


su




cat /proc/asound/cards

If the answer doesn’t have a line with speaker or headphone, the problem is at the kernel level.

🔧 Fastboot reset (if the sound is gone after firmware)

If the sound has disappeared after the update, try:

1. Turn off your phone and press Volume Down + Power to log in to Fastboot
2. Connect to the PC and do:

fastboot erase cache


fastboot reboot

⚠️ Warning: The fastboot erase and adb shell su commands require an unlocked bootloader. On new Xiaomi models (released after 2022), unlocking may result in a loss of warranty.
