How to Turn Off Sound When Xiaomi is Enabled: The Complete Guide

Many owners of Xiaomi, Redmi and POCO smartphones face an obsessive melody that sounds every time a device is launched: This is the standard behavior of the Android system in the shell of MIUI or HyperOS, designed to signal a successful boot.

However, for users who often reboot the gadget or use it in quiet modes, this sound becomes an annoying factor. Fortunately, there are proven methods to deactivate the system sound signal without the need to obtain superuser rights.

In this article, we will take a look at all the options available, from simple settings to advanced computer methods, and learn how to safely intervene in the work of system audio and forget about the welcome melody forever.

Why Xiaomi makes sound when downloading

The audio recording of the power-up process is part of a system resource sewn into the firmware in the factory, and the company's engineers add this audio file so that the user can audibly confirm that the device has passed the initial hardware check and is ready to go.

Unlike calls or notifications, this sound is not regulated by media or alarm clock volume sliders, but is classified as system sounds, which take precedence over user silence settings, which is why simply turning down the volume with buttons on the body before turning it off often doesn't help.

It is worth noting that on global firmware versions, this tune may differ from Chinese counterparts, in some cases, the sound depends on the chosen theme of the design, but most often it is strictly tied to the system partition, access to which is limited by access rights.

Understanding the nature of this sound is important, as the methods of turning it off depend on where the audio file is stored and how the Android operating system accesses it at the time of initialization.

Checking basic sound settings

Before we go into complex manipulations, we need to rule out software conflicts or active modes that can affect playback, and sometimes the problem lies in special feature settings or sound profiles.

First of all, check if the "No Sound" or "Do Not Disturb" mode is on all the time. Although this does not always block the boot sound, in some versions of MIUI it can suppress system signals.

Go to the Themes app and try to change the design to standard. Some third-party themes may have their own sound packages that conflict with or duplicate the system ones. This is an easy way to diagnose.

💡

If you use third-party launchers or system modifiers, try temporarily disabling them to check if they affect system sounds.

Disconnection through the Engineering Menu (CIT)

One of the most effective ways to remove sound is to use an engineering test menu, which is designed to diagnose hardware, but contains hidden settings that affect the device's start-up behavior.

To log in to the menu, you need to open the standard call app and enter a special code. On most Xiaomi devices, it is ##6484## or ##4636##. The interface may vary depending on the version of MIUI.

In the list that opens, select the item associated with Audio or Speaker. This may be the option "Boot Music" or "Power On Sound." If the switch is active, just deaktivate it. However, be careful not to change other settings, as this may disrupt the speaker.

It is important to understand that new versions of HyperOS may have limited access to these settings, and if there is no option, then the manufacturer has closed this option to ordinary users.

Using ADB to turn off the sound

The most reliable method, which works on 99% of devices without root rights, is the use of the Android debugging bridge (ADB), which allows you to send a command to the system to ignore the launch of the audio file at launch.

To start, you will need a computer (Windows, macOS or Linux) and a cable. USB. On your smartphone, you need to activate the developer mode. → About the phone and quickly press 7 times on the field "Version" MIUI" or “OS version".

Then, in the Advanced Settings menu → For developers, turn on the USB Debugging option. Connect your phone to your PC and allow access on your smartphone screen.

adb shell settings put global power_on_sound 0

This command changes the global variable that controls the sound, so if the first option doesn't work, you can try to force the sound to turn off by changing the volume of the system channel:

adb shell cmd audio set-device-connection-state 2 2 0

Modification of system files (Root Requires)

Users who have obtained SuperSU or Magisk rights can access the file system directly, allowing them to physically delete or replace the audio file that controls the melody.

Files are usually along the way. /system/media/audio/ui. You need a file called PowerOn.ogg or MIUI_power_on.ogg. Before any action, be sure to back up the original file.

The safest way to do this is to replace the file with an “empty” audio file with the same name and access rights. Download silence.ogg, rename it the system file, and replace the original file manager with root access (such as Root Explorer or MiXplorer).

⚠️ Warning: Incorrectly deleting system files can lead to a cyclic bootloop.Always have a working system backup or the ability to log in to Recovery on hand.

Once the file is replaced, you need to restart the device, and if done correctly, the phone will turn on completely silently.

💡

The ADB method is a “middle ground”: it does not require superuser rights, but it provides a guaranteed result on most devices.

Choose a method based on your technical background. If you are not confident in yourself, it is better to limit yourself to software settings.

Possible problems and solutions

Unforeseen situations may occur when the sound is turned off, for example, after applying ADB commands, the sound may disappear not only when it is turned on, but also in other system moments, such as locking the screen.

If this happens, you can return the settings by the reset command:

adb shell settings delete global power_on_sound

And users sometimes complain that the sound comes back after the system update, which is normal, because the firmware update often overwrites the changed system settings to factory settings, in which case the procedure will have to be repeated.

Do not forget that on some models, especially with heavily modified software from telecom operators, the sound can be “sewn” at the kernel level, and it is almost impossible to remove it without flashing it.
