How to change the sound of Xiaomi inclusion: a detailed guide

Changing the standard melodic jingle when booting the operating system is one of the most popular ways to personalize a smartphone. Owners of Xiaomi, Redmi and POCO devices often look for a way to replace the familiar sound with something more unique or, conversely, turn it off completely for silence. However, standard means of the MIUI or HyperOS interface can not do this directly, since the manufacturer did not provide such an option in the settings menu.

However, it is still possible to change the system audio file, which requires access to system folders and an understanding of the structure of Android directories. In this article, we will discuss the safe methods for replacing a PowerOn.wav or PowerOn.ogg file, and also discuss the nuances of working with superuser rights.

Before you start to act, you need to prepare the device, you need a file manager with extended rights or a connection to the computer, you also need to download or create the desired audioflick, remember that the format must be compatible with system requirements, otherwise you will hear silence or static noise instead of music.

Audio file preparation and format requirements

The first step is to find or create a suitable sound file.The Android system, and in particular the shell from Xiaomi, has strict requirements for the format and duration of the track that will be played at start.If the file is too long, it will simply crop or not play completely, as the download process takes a certain time.

The optimal format for system sounds is WAV or OGG. These formats provide fast decoding and minimal load on the processor at the time of service startup. Using heavy formats like FLAC or MP3 with high bitrate can lead to playback delays or errors.

💡

The ideal sound duration is 2 to 4 seconds, and longer tracks may not be able to play before the lock screen appears.

It is also important to consider sampling frequency. For system sounds, the 44.1 kHz or 48 kHz standard is usually suitable. If you are converting music yourself, make sure that the channels are stereo-converted, although the mono tracks will also work correctly. Check the file on your device before replacing the system one to make sure it is quality.

• 🎵 Download the finished ringtone in.wav or.ogg format from a reliable source.
• ✂️ Use an audio editor on a PC or in an app to crop the track to 3-5 seconds.
• 📂 Rename the file to PowerOn.wav (or PowerOn.ogg) to match the original system name.
• 📱 Save the prepared file to your phone memory, preferably to the Downloads folder for quick access.

Replacement method through file manager with Root rights

The most reliable way to change the on sound is to directly replace the system file, and you need to have Root rights, without which access to the system partition /system/media/audio/ui will be closed to recording, and if your smartphone is already rooted (like Magisk), this method will only take a couple of minutes.

To work, you will need an advanced file manager that supports Root, such as Root Explorer, MT Manager or Solid Explorer with root mode enabled. After running the application, you must grant him superuser rights by confirming the request in the Magisk or SU window.

Navigating the system requires attention. You need to go to the root directory and find your way. /system/media/audio/ui. Some firmware versions may have slightly different paths, but folder structure is usually saved. Once you find the original file, rename it (e.g., in the file). PowerOn_old.wav) Or copy it to a safe place, and that's critical to the ability to roll back change.

⚠️ Warning: Never delete the original system file without a prior copy!If the new file is incorrect, the absence of the original may result in interface errors or the absence of any system sounds.

Once you have backed up, copy your prepared PowerOn.wav file to the same folder. Make sure that the permissions of the new file match the rights of the deleted original.--r-- (Change of access rights can be done in the same file manager through the file properties menu.

Replacement of sound without Root rights: system themes

For users who don't want to get super-user rights and risk warranty, there is an alternative, though less flexible, method: using the Mi Themes app. Some copyright themes contain modified system sounds, including the on sound.

To use this method, open a standard Theme app on your device. In the search bar, type in queries like "No boot sound," "Custom boot," or "Silent boot." Authors often create themes that replace system sounds with silence or short signals.

Once you find the right theme, apply it. Note that using the theme can change not only the sound, but also the icons or wallpaper. In the theme settings, you can choose to use only certain components, leaving, for example, only Sounds.

Note that this method does not work on all versions of MIUI and HyperOS. In recent security updates, Xiaomi has limited the ability to change critical system sounds. If the sound has not changed after applying the theme, then your firmware version blocks this feature.

Using ADB to modify system files

If you don’t have Root rights, but you’re a confident PC user, you can try the method using debugging by USB tool ADB (Android Debug Bridge: This method requires that the smartphone be connected to the computer, and the PC has drivers and platform toules installed.

First, you need to activate the developer mode. Go to Settings. → About the phone and seven times quickly click on the build number (MIUI Version. Then on the menu → For developers, turn on the debugging by USB. Connect your phone to your computer with a cable.

adb devices


adb push PowerOn.wav /sdcard/PowerOn.wav




adb shell




su




mount -o rw,remount /system




cp /sdcard/PowerOn.wav /system/media/audio/ui/PowerOn.wav




chmod 644 /system/media/audio/ui/PowerOn.wav




reboot

This is essentially a duplicate of the file manager, but it's done through the console. mount -o rw,remount /system puts the system partition into read-write mode. Without this command or without su (root) rights, you can't copy the file. If you don't have superuser rights, ADB will only allow you to copy files into user memory, not replace the system memory.

There is also the option of using ADB to remove standard audio without replacing if the system allows override, but this works rarely and depends on the specific version of Android.In most cases, replacing a file via ADB still requires having Root access on the device.

How to completely turn off the sound of the switch on

Many users don't want to replace it, but to remove the sound of the switch on so as not to disturb others in quiet places like a movie theater or a library. The easiest way is to use the Silence theme or a theme where the sound of the switch on is replaced with an empty file. However, if the themes don't help, you can create your own "empty" file.

To do this, create an audio file on your computer that lasts 1-2 seconds, which contains absolute silence (digital silence, not just the absence of a track). Save it in.wav format with the name PowerOn.wav. Next, follow the instructions for Root users: replace the original system file with this "empty" file.

The alternative is to use Do Not Disturb or No Sound modes, but standard on-screen audio often ignores the media volume profile and plays even when the sound is off, so replacing the file with a quiet one is the only guaranteed way to achieve complete silence when the system starts at the software level.

⚠️ Note: When replacing system files, always keep the original firmware or TWRP-Backup: An access error or damage to the system partition can result in a cyclic reboot (bootloop).

Possible problems and solutions

There are a lot of difficulties in modifying system files, and one of the common problems is that there is no sound after replacing, which may mean that the file format is not supported by the codec at the early boot stage, or the file name is written with an error (letter register means PowerOn.wav and poweron.wav are different files on Android Linux).

Another common issue is resetting changes after a system update: When you upgrade MIUI or HyperOS, the /system partition is overwritten, and all your modifications will be lost, and you will have to repeat the replacement procedure after each major firmware update.

💡

If the phone goes into reboot after replacing the file, immediately boot to Recovery Mode and restore the original file from the backup or make a data wiping if there is no backup.

Also worth mentioning is the access rights issue: If you just copied a file but didn't change its permissions to 644, the system may not consider it executable or readable system processes. Always check the file attributes after copying.

In rare cases, antivirus systems or Xiaomi’s built-in protection can block the change of system files even if there is Root, in which case it helps to temporarily disable protection in security settings or use specialized Magisk modules that implement changes to the system in a softer way (Systemless).
