Xiaomi smartphone owners often face situations when you need to urgently turn off the speaker’s sound — whether it’s an unexpected call at an important meeting, annoying advertising in the application or a breakdown of the audio system, which causes the phone to make constant noise. Unlike a simple transfer to silent mode, a complete turn off of the speaker requires deeper manipulation of the settings.
In this article, we'll look at all the ways you can do it, from standard MIUI features to hidden engineering menus and third-party utilities. It's important to understand that some methods can temporarily prevent you from hearing notifications or phone calls, so use them consciously. If your goal is to just remove the sound of a call, just activate Do Not Disturb mode. But if the speaker is physically damaged and makes a constant squeak, its software shutdown will be a temporary solution before repair.
The instructions in the article are relevant for all modern Xiaomi models, including the Redmi Note series. 12/13, POCO X5/F5, Mi 11/12/13, and the devices on MIUI 14/15 (including global and Chinese firmware versions. MIUI 12 Some of the methods may not work, due to changes in the architecture of the sound subsystem.
1.Switch off speaker via "Do Not Disturb" mode
The easiest and safest way to do this is to use the built-in Do Not Disturb (DND) mode, which doesn't physically turn off the speaker, but blocks all notification, call and media sounds, and this is a good way to do it if you need to temporarily eliminate noise without making any deep changes to the system.
How to activate:
- Open the Settings. → Sound and vibration.
- Slap on the item Do not disturb.
- Turn the switch on to the "On" position.
- Set exceptions (for example, allow alarm clocks or repeat calls).
Note that in this mode, the multimedia sound (video, games) will also be turned off if the individual rules are not configured, and to return the sound, you just need to turn off the mode through the notification panel or in the settings.
2. Completely disabling media sound in settings
If the goal is to turn off sound only in applications (such as games or browsers) but leave calls and notifications to work, use a separate media volume setting, which does not require superuser rights and works on all versions of MIUI.
Instructions:
- 🔊 Click on the physical volume button on the side panel of the phone.
- 📱 In the panel that appears, tap on the icon ⚙️ (Settings) next to the volume slider.
- 🔇 Move the Media slider to the far left position.
- 🔒 Block the slider by clicking on the lock icon (optional).
This method doesn't shut down the speaker completely -- the sound of the calls, the alarms, the system notifications will remain active, and to get the sound back, just move the slider back.
💡
If some applications (such as TikTok or YouTube) still emit sounds after disabling media sound, check their individual settings - some programs ignore system limitations.
3.Use of the engineering menu (for experienced users)
The engineering menu (#4636##) allows you to deeply customize the parameters of the sound system, including turning off the speakers. This method requires caution - incorrect changes can lead to malfunctions in the audio.
Step-by-step:
- Open the Phone app and enter the combination: ##4636##.
- In the menu that appears, select Hardware testing.
- Go to the Audio section (Sound).
- In the list of tests, find the Speaker Test.
- Press Stop Test – this will turn off the speaker before the device restarts.
⚠️ Warning: After this method is applied, the speaker will stop working including calls and notifications. To return the sound, restart the phone or re-start the test in the engineering menu.

4. Disconnect speaker via ADB (for advanced)
If standard methods don't work, you can use Android Debug Bridge (ADB), a debugging tool that allows you to manage system parameters through a computer, which is suitable for devices with an unlocked bootloader or root rights.
What you need:
- 💻 A computer with installed Xiaomi drivers and ADB.
- 🔌 USB-cable (preferably original).
- 📱 Included debugging by USB on the phone (Settings) → The phone. → Version. MIUI — Tap 7 times, then return to the additional → For developers → Debugging by USB).
Commands to disable the speaker:
adb shell
su
settings put global volume_music 0
settings put global volume_alarm 0
settings put global volume_notification 0
settings put global volume_system 0
settings put global volume_voice 0To return the sound, replace 0 with the desired volume value (e.g. 5).
Install Xiaomi drivers on PC
Download Platform Tools from Google
Turn on USB debugging on your phone
Connect your phone to your PC in file transfer mode
Check the connection with the adb device command

5. Sound control applications
If you need to flexibly adjust the sound without manual interference, use third-party applications that allow you to turn off the speakers on a schedule, block the sound in individual applications or completely silence the audio output.
Top.-3 apps:
| Annex | Functions | Need a Root? |
|---|---|---|
| SoundAssistant | Separate volume control for each application, block the sound on a schedule | No. |
| MacroDroid | Automatically shutting down the sound when running certain programs | No. |
| Disable Audio | Disabling the speakers completely (requires ADB or Root) | Yes. |
⚠️ Note: Apps like Disable Audio can conflict with system processes MIUI. Before use, back up your data through Settings. → Additionally. → Backup and reset.
6. Hardware switch off speaker (extreme case)
If software methods don't work (e.g., the speaker is damaged and squeaks constantly), there's a physical shutdown, which requires disassembling the phone and is only suitable for power users or service centers.
How it works:
- 🛠️ The speaker is connected to the motherboard through a plume or solder.
- 🔌 Unconnecting the plume or cutting the tracks on the board will completely de-energize the speaker.
- 📵 After that, the sound will only go through headphones or Bluetooth devices.
Risks:
- 🚫 Loss of warranty (if the phone is under warranty).
- 💥 Damage to other components in careless disassembly.
- 🔊 Inability to return sound without soldering or replacing the plume.
💡
Physically turning off the speaker is an irreversible process. If you are unsure of your skills, contact a Xiaomi service center or an electronics repair shop.
Frequent problems and solutions
Even after you turn off the speaker, you might have some unexpected difficulties, and we'll look at the typical situations and the ways in which they're done.
Problem 1: The sound is gone, including the headphones.
🔹 Solution: Reset the sound settings through Settings → System system → Resetting settings → Reset the sound settings. If that doesn't work, check if Monozvoouk is activated in the special features settings.
Problem 2: After using ADB, the sound does not return.
🔹 Solution: Enter adb shell settings delete global volume_music For each type of sound (replace the music with alarm, notification, etc.
Problem 3: The speaker emits wheezing or crackling after shutting down.
🔹 Solution: This is a sign of a physical malfunction. Try to clean the speaker with compressed air.
