Why does Xiaomi phone make sound when turned on and can it be removed?
The audio signal when Xiaomi boots is a proprietary feature of MIUI firmware that tells the user that the system is running successfully. For some, it is a familiar interface element, and for others it is an annoying factor, especially if the phone is rebooted at night or in a quiet room. Unlike Samsung or Google Pixel, where the boot sound is turned off in two clicks, in Xiaomi this option is often hidden or not at all in the standard settings.
The difficulty is that the sound is played at the bootloader level before Android is fully initialized, which means that conventional methods like turning down the volume or putting the phone in silent mode don't work. However, there are workarounds, from simple tricks with settings to deep interference with system files. In this article, we'll look at all the current methods, including those that work on the latest versions of MIUI 14/15 and HyperOS (2026).
We warn you right away: some methods require unlocking the bootloader or the rights of the superuser (root).If you are a beginner, start with safe options (sections 2-3), and resort to radical measures (ADB, modification of system files) only when you are confident in your actions.
Method 1: Disconnect via MIUI settings (works on some models)
The most obvious and safe method is to search for the option in standard settings. Unfortunately, Xiaomi periodically removes or moves this item depending on the firmware version.
- π MIUI 12-14: Go to Settings β Sounds and vibrations β System sounds and look for switch Loading sound or Turn on sound.
- π± HyperOS (2026): The way has changed - try Settings β Display and sound β Additional settings β Systemic sounds.
- π Search by settings: enter in the search box settings the request βboot soundβ or βboot soundΒ».
If you donβt have an option, donβt despair β thatβs normal for most Redmi and POCO models.
β οΈ Note: Some firmware (e.g. Xiaomi) EU Or custom builds, this option can be called Power-on sound or Boot animation sound, and don't confuse it with Lock/Unlock sounds, which are different features!
Method 2: Use of Do Not Disturb (Backway)
If the download sound is not turned off through the settings, you can use the automatic rule in Do Not Disturb (DND) mode, which does not remove the sound completely, but makes it inaudible at certain hours:
- Open Settings β Sounds and vibrations β Do not disturb.
- Activate the switch on schedule.
- Set a time, for example, from 23:00 to 07:00 (when the phone usually restarts the least).
- In the Exclusions section, turn off all options, including alarms and notifications.
Now, if the phone reboots in that time frame, the sound will be blocked, and the downside is that it only works at specified hours and is not suitable for daytime reboots.

If you have HyperOS, the path to Do Not Disturb settings may be hidden. Try calling the Quick Settings Panel (swipe down from the top edge of the screen) and holding the Do Not Disturb icon will open up advanced settings.
Method 3: Turning off the sound via ADB (without root)
If standard methods donβt work, itβs time to move on to more advanced tools. Android Debug Bridge (ADB) allows you to turn off the download audio without getting root permissions, but requires you to connect the phone to your computer, a method that works on most Xiaomi, Redmi and POCO models with MIUI 10-15 and HyperOS.
What you need:
- π₯οΈ Computer with Windows/macOS/Linux.
- π Cable USB (preferably original).
- π οΈ Utility. ADB Platform Tools (download and unpack).
- π Included Debugging by USB on the phone (path: Settings) β The phone. β Version. MIUI β 7 times tap the version β return to additional settings β For developers β Debugging by USB).
Step-by-step:
- Connect the phone to your computer and confirm the trusted device in the dialog box on the screen.
- Open the command line (Windows) or terminal (macOS/Linux) in the folder with the platform-tools.
- Enter the command to check the connection: Adb devices must appear serial number of your device.
- Execute the command to disable the download sound: adb shell settings put global boot_sound 0
- Reboot your phone: adb reboot
If the sound is gone after the reboot, congratulations! If not, try an alternative command (for some firmware):
adb shell su -c "setprop persist.sys.boot.sound 0"Note: The second command requires root rights.

Method 4: Removing system sound via TWRP (for advanced)
If ADB didnβt help, and you donβt have root rights, you can go to radical measures to delete the download audio file through custom recovery TWRP. This method is suitable for users who have already unlocked the bootloader and installed TWRP.
Warning: Mistakes in TWRP can lead to data loss or system damage.
Instructions:
- Load the phone into TWRP mode (usually by clamping Power + Volume up).
- Go to Advanced β File Manager.
- Open /system/media/audio/ui/ (the path may vary depending on the firmware).
- Find files with names: boot_animation_sound.mp3 poweron_sound.mp3 miui_boot_sound.mp3
Delete
.bak
Reboot the phone.
If the sound is gone, the task is done. If it is not, the sound file is stored elsewhere (e.g., in /system/product/media/).
β οΈ Note: On some Xiaomi firmware, the download sound can be embedded in bootanimation.zip. Deleting this file will make the download animation disappear, but it won't always remove the sound!
What if the phone does not boot after deleting the files?
Method 5: Modification of system files (requires root)
For root-right users, there is another reliable way to edit the system files that play back sound, which is universal and works on all versions of MIUI and HyperOS.
Tools required:
- π± Phone with unlocked bootloader and root rights (for example, via Magisk).
- π οΈ File Manager with support for root (such as Root Explorer or Mixplorer).
- π Patience β The process requires care.
Step-by-step:
- Open the file manager and go to /system/build.prop.
- Find a line: ro.config.boot_sound=1 and replace 1 on 0.
- If there is no line, add it to the end of the file.
- Save the changes and restart the phone.
The alternative is to edit the file. /system/media/audio/ui/boot_audio_policy.conf (if there is one, replacing all references to the download sound with empty values.
| Method | Difficulty | Need root? | It's running HyperOS? | Risk of system damage |
|---|---|---|---|---|
| MIUI settings | β | β No. | β Yes. | β No. |
| Do Not Disturb mode | ββ | β No. | β Yes. | β No. |
| ADB-team | βββ | β No. | β Yes. | β οΈ Low. |

The most secure methods are through MIUI or ADB settings. Methods with TWRP and root are suitable only for experienced users, as they carry the risk of damaging the system.
What do you do if nothing helps?
If youβve tried all of these methods, but the sound is still heard when you turn on, itβs possible that one of the following factors is the cause:
- π Custom firmware: Some builds (e.g. Xiaomi.EU or LineageOS) may ignore standard commands. Try changing firmware or contacting its developers.
- π Manufacturer policy: on new models (for example, Xiaomi 14 or Redmi Note 13) the download sound can be hard sewn into the bootloader.
- π Firmware bug: sometimes the sound comes back after the update. Try to roll back to the previous version. MIUI or wait for the patch.
If it is critical to remove the sound and standard methods donβt work, consider the following options:
- Contact the service center: some workshops offer a service to disable the audio download through service utilities (for example, Mi Flash Pro).
- Buy a phone without sound: for example, the POCO F5 or Redmi K60 models on global firmware sometimes lack this feature.
- Use a soundproof case: a radical but working method for those who do not want to mess with settings.
Important: On some Xiaomi phones, the download sound is part of the diagnostic system, and its absence can make it difficult to identify problems when contacting the service center.
