How to turn on the sound on Xiaomi Redmi: 7 proven ways (including hidden settings)

Why Xiaomi Redmi lost the sound and how to fix it?

You picked up your Xiaomi Redmi, but suddenly you found that the sound didn't work: no music, no notifications, no calls, and the situation is familiar to many owners of smartphones of this line - from the budget Redmi 9A to the flagship Redmi K60 Pro. The reasons can be different from accidental button pressing to software failures after the MIUI update.

In this article, we’ll look at all the ways you can turn on your Xiaomi Redmi devices, including little-known tricks with engineering menus and resetting. It’s important to understand that the algorithm of actions depends on the specific situation: the sound was lost completely or only in the dynamics, after a drop or update, on calls or in applications. We structured the material so that you can quickly find a solution to your problem, from simple to complex.

If you're in a hurry, use the FAQ at the end of the article, which is the answer to the most common questions. For a deeper analysis, read on: we'll go through each method in detail with explanations and warnings.

1. Check basic settings: buttons and volume controls

To start with, the obvious is that often the sound on Xiaomi Redmi "disappears" due to accidental physical button pressing or a failure in the volume scale.

• 🔊 Volume buttons on the sidebar: press the top button (magnify) 2-3 times. Sometimes the scale is knocked down to "0" after removing the smartphone from the case or pocket.
• 🔔 No Sound Mode: Some models (Redmi Note 11, Redmi 10) have a separate switch on the left side.
• 📱 Volume scale in the notification bar: swipe from top to bottom and tap the speaker icon. Make sure the slider is not at a minimum.
• 🎵 Sound Profile: in Settings → Select Sound and Vibration Mode (not Vibration or No Sound").

On Redmi models with NFC (such as the Redmi Note 12 Pro+), the switch on the sound button may conflict with payment functions. If the sound is lost after you put the phone to the terminal, restart the device.

If you don't hear the sound after this manipulation, move on to the next section. If you've solved the problem, remember that Xiaomi often has protection against random taps in your pocket, so lock the screen before you remove the phone.

Problems with the speaker: how to check for hardware malfunction

If the sound is completely absent (including calls, music, and system notifications), the hardware speaker may break.

1. Speaker test via engineering menu: Dial on the phone keyboard ##4636## → select Phone Information → Speaker test. If there is sound, the settings are a problem, if not, the iron part.
2. Headphone check: Connect your wired or wireless headphones, and if you have sound in them and you don't have it in the speaker, you're probably out of touch, or the speaker itself.
3. Visual inspection: Light a flashlight into the speaker grille (usually at the bottom of the case) if dust, moisture or mechanical damage is visible, repairs will be required.

If you are not sure about your skills, do not disassemble the phone yourself - on Redmi models with IP53 (for example, Redmi Note 11S) it is easy to damage the seals, which will lead to loss of moisture protection.

3. Resetting the sound settings to factory

If the sound is gone after updating MIUI or installing third-party applications, resetting the audio settings will help, a method that doesn't affect personal data, but will return all the audio settings to the "out of the box" state.

Instructions:

1. Open Settings → System and device → Additional → Resetting.
2. Select Reset audio settings (on some models it may be called Reset sound by default).
3. Confirm the action. The phone will reboot.

After the reboot:

• 🔄 Check the volume in Settings → Sound and vibration.
• 🎶 Run any audio app (such as Mi Music or YouTube).
• 📞 Ask someone to call you to check the sound of the call.

Attention! On Redmi models with dual speakers (Redmi K50, Redmi Note 12 Pro+), after reset, you may need to recalibrate the sound. To do this, go to Settings → Sound → Setting up the speakers and follow the instructions on the screen.

4. Sound recovery through the engineering menu (for advanced)

If standard methods don’t work, you can try to recover sound through an engineering menu (Engineer Mode), which is suitable for experienced users, as improper actions can lead to failures.

Instructions for Xiaomi Redmi based on Qualcomm (most models):

1. Open the Phone app and dial ##36446337## (code may vary for different MIUI versions).
2. Go to the Hardware Testing → Audio section.
3. Select LoudSpeaker Mode and run the test.
4. If the sound is in the test, but not in the system, click Restore Default.

For models on MediaTek (e.g. Redmi 9A, Redmi 10A):

1. Dial ##4636## → Hardware info → Audio
2. Check the Speaker Test and Headset Test settings.
3. If the Normal value is not sound, reset the settings via Reset Audio.

On some firmware, the engineering menu may be blocked, in which case only flashing through Fastboot or contacting the Xiaomi service center will help.

💡

Before entering the engineering menu, back up your data via Settings → About Phone → Backup. This will save you from losing information in the event of an accidental crash.

5. Software glitches: reboot, safe mode and updates

Often, the sound on Xiaomi Redmi is lost due to application conflicts or errors in MIUI. Here's how to diagnose and fix software problems:

• 🔄 Forced reboot: Press the power button for 10-15 seconds until the phone turns off and turns on again.
• 🛡️ Safe Mode: Press the power button → Hold your finger on "Switch off" → Select "Safe Mode." This mode only runs system applications. If sound appears, the problem is in one of the installed applications (most often in sound optimizers or launchers).
• 📲 Update MIUI: Go to Settings. → The phone. → Update. If you have an update, install it. New versions often fix bugs with sound.
• 🧹 Cache cleaning: In Settings → Annexes → App management find Mi Sound, Media Storage and Bluetooth, then click Clear Cache".

If the sound is lost after installing custom firmware (for example, LineageOS or Pixel Experience), the problem may be incompatibility of drivers, in which case only the firmware on the official MIUI via Fastboot will help.

💡

Safe Mode is the fastest way to detect application conflict, and if the sound is working, delete the apps one at a time, starting with the last ones installed until the problem is resolved.

6 Hard Reset as a last resort

If none of these methods work, you'll have to completely reset your phone, which will delete all the data from your phone, so only use it as a last resort. Back up first!

Instructions for Xiaomi Redmi:

1. Turn off the phone.
2. Press the power and volume button for 10-15 seconds at the same time until the Mi logo appears.
3. From the Recovery menu, select Wipe Data (use volume buttons for navigation and power button for confirmation).
4. Confirm the action by selecting Yes.
5. After reset, select Reboot.

If the sound doesn't come back after the reset, it's almost certainly hardware.

• 🔧 Contact the authorized Xiaomi service center (list on the official website).
• 📄 Keep a check or warranty card – on a model up to 2 years, repairs can be free.
• 💰 Check the cost of replacing the speaker in advance: on the Redmi Note series it is usually 1,500-3000 ₽, on flagships (Redmi K) - up to 5 000 ₽.

Attention! On Redmi models with LPDDR5 memory (for example, Redmi K60) self-flashing through the Fastboot can lead to the loss of IMEI. If you are not sure of your abilities, trust the repair professionals.

7. Specific issues: calls, notifications, Bluetooth

Sometimes the sound is lost selectively, like notifications, but you can't hear the person you're talking to while you're calling, or vice versa.

📞 No sound on the bells.

• Check if the Loud Communication mode is activated (the tube icon with waves at the top of the screen).
• B Settings → SIM-Maps and mobile networks select "Voice Call" → "Call settings" → "Call sound through the speaker".
• If you use TrueCaller or other number identifiers, temporarily delete them.

🔔 No notifications sound.

• In Settings → Notifications, check if the sounds are turned off for specific applications.
• Make sure that the tune is selected in Settings → Sound → Notification sounds (not “No Sound”).
• Try changing the theme of sounds: Settings → Themes → Sounds.

🎧 Bluetooth Sound Problems

• Remove the device from the list of conjugates and connect again.
• B Settings → Connected devices → Bluetooth on. HD-audio (if available).
