How to turn on the sound on the smartphone Xiaomi Redmi: step-by-step instructions

The sound on the Xiaomi Redmi smartphone can be lost for dozens of reasons, from a banal error in settings to hardware malfunctions. If your phone suddenly stopped playing music, you can not hear the notifications or the interlocutor does not hear you during the call, do not rush to carry it to the service center. In 80% of cases, you can solve the problem yourself in 2-3 minutes.

This article will help you understand how to turn on the sound on the Redmi Note 10/11/12, Redmi 9/10/13C and other models of the series. We will look at all possible scenarios, from checking basic settings to diagnosing software failures, focusing on typical user errors that lead to “deafness” of the smartphone, and give a checklist for quick check.

If after reading the instructions, the sound never appeared, at the end of the article you will find a table with symptoms that indicate a specific malfunction (for example, why only one speaker works or why there is sound in headphones, but not in speakers).

1. Checking basic volume settings

To start with, the obvious is that it's possible that the sound is just turned off or minimized. Xiaomi Redmi has separate volume controls for media, calls and alarms, and they're easy to confuse, especially if you've recently updated MIUI.

To check:

• 🔊 Press the physical volume button on the side of your smartphone. A slider will appear on the screen. Make sure it's not at zero.
• 🎵 If the sound is only missing from apps (YouTube, Spotify), check the volume directly in the app itself – sometimes it resets after an update.
• 📞 For calls: Open Settings → Sound and vibration → Loudness and check the slider "Call".

Some Redmi models (like the Redmi Note 11 Pro+) have a Quiet Mode feature that turns off all sounds except the alarm clock to turn it off:

1. Swipe down from the top edge of the screen to open the notification bar.
2. Find the badge. 🔔 "Sound and touch it. If it's crossed out, tap it again.

💡

On MIUI 14 and later, the notification panel can display a separate switch for "No Sound", "Vibration" and "Sound". Make sure that the latter option is selected.

⚠️ Note: If the sound only appears in headphones after the volume change, but not in speakers, the problem may be a contaminated Type-C connector or in the audio output settings (more on this below).

2. Switching sound modes (speakers/earphones/Bluetooth)

Xiaomi Redmi smartphones sometimes forget to switch back to speakers after connecting headphones or Bluetooth devices. This is a common reason why sound is in the headset, but not when playing through speakers.

How to check:

• 🎧 Turn off all headphones (wired and wireless). If you've used a Type-C headset, physically unplug it.
• 🔄 Reboot your smartphone. Once you restart, the system should automatically return the sound to the speakers.
• 🔊 If the sound does not return, open any audio application (such as "Music") and manually select the output device: → Output device → Phone speaker

There's a bug on MIUI 13/14 that freezes in Bluetooth audio even after the device is turned off, to reset the settings:

1. Go to Settings. → Connected devices.
2. Find the Bluetooth section and disable all connected devices.
3. Return to Settings → Sound and Vibration → Additional → Sound output and select Dynamic.

3. Diagnostics of hardware problems

If the sound doesn’t work in any app (calls, music, video) and all settings are checked, the problem may be in the hardware.

• 🔈 Lower speaker (responsible for media and speakerphone calls).
• 📞 Top speaker (used for spoken sound).
• 🔌 Audio chip (when the sound is broken, the sound disappears completely, even in headphones).

Do a quick diagnosis:

To check the speakers:

1. Call the phone from another device, and if you hear the person you're talking to but they can't hear you, the problem is the microphone.
2. Play the video on YouTube. If the sound is only coming from the top speaker, the bottom speaker is faulty.
3. If you have audio in them and you don't have speakers, it's the hardware problem.

⚠️ Warning: If your smartphone falls or gets wet, don’t try to disassemble it yourself – this can lead to a short circuit.

4. Resetting the sound settings to the factory

If the audio is lost after updating MIUI or installing new applications, resetting the audio settings will help, which will not delete your data, but will return all audio settings to the default state.

Instructions:

1. Open Settings → System and device → Additional → Resetting.
2. Select Reset audio settings (on some firmware, the item may be called “Reset Media settings”).
3. Confirm the action and restart the smartphone.

After discharge:

• 🔊 Check the volume in Settings → Sound and vibration.
• 🎵 Run any audio application and reset the sound.
• 📞 Make a test call.

If the reset didn’t help, try resetting all settings (without deleting data):

1. Settings → About the phone → Reset settings → Reset settings.
2. Select "Reset network, sound and display settings".

5. Verification of system updates and flashing

On Xiaomi Redmi, the sound may be lost due to firmware bugs, especially after major MIUI updates. For example, MIUI 13.0.4 for the Redmi Note 10 Pro had a bug that caused the speakers to shut down after connecting to the Bluetooth speaker.

How to update the system:

1. Open Settings → About the phone → System update.
2. Click "Check Updates." If a new version is available, download it and install it.
3. After the update, be sure to reset the sound settings (section 4).

If the update didn’t help or it didn’t, try reflashing the smartphone manually:

• 📥 Download the latest stable firmware for your model from the official Xiaomi website.
• 🔄 Use Fastboot or Recovery to install (instructions are available on the forums) 4PDA or XDA Developers).
• ⚠️ Before the firmware, make a backup copy of the data!

💡

If the sound is gone after the update, try to roll back to the previous version of MIUI. To do this, download the archive with the firmware and install it through Recovery.

6. Elimination of program conflicts

Sound control applications (equilibrium equalizers, modified players) or viruses can block the system audio output. If the sound is lost after installing new software, follow the following steps:

Step 1: Verification of Application Permissions

1. Open Settings → Applications → Application Management.
2. Find applications that work with sound (e.g. ViPER4Android, Equalizer).
3. Go to Permits and turn off microphone/sound access.

Step 2: Safe mode

Download your smartphone in Safe Mode to disable all third-party apps:

1. Press the power button before the off menu appears.
2. Press and hold the "Switch off" item until a request to switch to safe mode appears.
3. Check the sound after download, and if it appears, it's a problem in one of the installed applications.

Step 3: Delete suspicious programs

Delete:

• 🎛️ Applications for audio tuning (equilizers, modified players).
• 🛡️ Antiviruses and “optimizers” (e.g. Clean Master, DU Speed Booster).
• 🎮 Game emulators (may conflict with audio drivers).

7. Clean connectors and speakers

Dust, moisture or debris in the Type-C connector or under the speaker grid is a common cause of sound loss. On the Redmi, the bottom speaker is particularly vulnerable because it is located next to the charging port.

How to Clean a Type-C Connector:

1. Turn off your smartphone.
2. Use a wooden toothpick or plastic spatula to gently remove debris from the connector. Do not use metal objects!
3. Blow the connector with compressed air (a canister for cleaning equipment).

How to clean the speakers:

• 🧹 Use a soft brush (such as for drawing) to remove dust from the mesh.
• 💧 If the speaker is wet, put the phone in a bag with silica gel on 12-24 Don't dry with a hair dryer!
• 🔊 To check, turn on the maximum volume and hold the phone to your ear. If there's a sound but it's quiet, the speaker is contaminated.

⚠️ Warning: If the sound becomes hoarse or intermittent after cleaning, it may indicate damage to the speaker membrane.
