Changing standard tunes is one of the easiest ways to personalize your smartphone by making it truly unique.However, when it comes to system sounds like locking the screen, users often face the limitations of the MIUI or HyperOS shell. Standard settings make it easy to change ringtones for incoming calls or notifications, but hide options for deep customization of the interface.
Many Xiaomi device owners wonder if it is possible to change this sound without obtaining superuser rights (root). Fortunately, the answer is yes: there are proven methods to circumvent standard restrictions. You do not need to be an expert in programming or risk the device warranty to install the desired audio file to lock.
In this article, we will take a look at all the available ways to replace sound, from built-in theme tools to more advanced methods using file managers. We will look at the nuances of working with MIUI different versions and show you how to avoid common errors when working with system files.
Why Standard Settings Hide the Sound Change Option
Xiaomi’s policy on the interface MIUI So, it's all about creating a common visual and sound style, which is why you don't find a separate slider on the Sound and Vibration menu. mp3-The system is tightly tied to the chosen theme of the design, which ensures the integrity of perception, but limits the freedom of the user.
The standard operating mechanism of the Android sound engine in conjunction with the MIUI shell assumes that the lock sound is part of the theme package. This means that it formally requires changing the theme entirely or modifying the theme files. System restrictions do not allow you to simply select a file from memory, as is done with the ringtone of a call.
However, there is a loophole in how Android handles file priorities: If a file with a specific name in the right directory is present, it can overwrite standard system sound, and that's the principle behind all secure root-enabled customization methods that allow you to swap standard audio files for custom audio files.
⚠️ Note: Before making any changes to system folders or theme files, it is strongly recommended to back up important data.While the methods described are safe, accidentally deleting critical files can result in resetting the theme settings.
Understanding this architecture is important for executing an instruction, because you don't break the system, you use the system's file prioritization capabilities wisely, and that's a key difference from root access, where you directly replace protected system files in /system/media/audio/ui.
Audio file preparation and format requirements
The first step to personalization is to prepare the audio file itself. Not every music track is suitable for this purpose, since the lock sound should be short, clear and not annoying when you listen to it often.
Android and MIUI shell work best with MP3 or OGG. Using other formats such as WAV or FLAC can cause sound to simply not play or be played with a delay. It is recommended to use a bitrate of at least 128 kbps to ensure quality sound.
To edit an audio file, you can use online services or special editor apps available on Google Play. You need to crop the track, leaving only the desired snippet, and save it in a convenient place, for example, in the Downloads or Music folder.
💡
Use applications to create fade-in and fade-out effects on the edges of the audio file, which will make the lock sound more pleasant and natural, without sharp cliffs.
It is also important to pay attention to the file name. Although the file name inside the archive is important in the theme method, it is sufficient to give the file a clear name in Latin to avoid encoding problems in file managers for initial preparation.
- 🎵 The file format should be MP3 or OGG for maximum compatibility.
- ⏱️ The duration of the sound should not exceed 2-3 Seconds, or he'll be circumcised.
- 📂 Save the source file in an accessible folder to easily find it when needed.
- 🔊 The volume of the file should be sufficient, but not deafening, as system amplification can vary.
Replacement method through the “Themes” application (Safe way)
The most reliable and secure way to change the lock sound is to use the official Themes app, preinstalled on all Xiaomi smartphones, which does not require access to system files and is completely reversible at any time, the essence of the method is to install a theme in which the lock sound has already been changed, or modify an existing theme.
To start, open the Topics app and go to Profile (the person icon in the lower right corner) and we're interested in My Topics, pick any topic you like visually, or download a free theme from a directory that supports customization of sounds.
Next, you need to apply the topic. After applying, go to the theme settings (hold your finger to the topic preview in the section "My topics» -> «Customize"). In some versions MIUI You can select "Block Sound" separately here, and if you don't have that option, we use the method of swapping a file inside the theme package, but through the secure file manager interface, if it allows you to access it. MIUI/theme.
But there's an easier way to do this, which is to find a theme in a theme store called System Sounds or UI Sounds, which is designed specifically to replace the interface without changing the wallpaper or icons, and to set up a theme is the fastest way to get a new lock sound.

⚠️ Note: When using third-party themes editors, make sure you download them from trusted sources. Modifying theme packages can lead to application errors if the archive structure is broken.
Using third-party file managers for advanced
For those who want full control and are not afraid to work with the file system, there is a method of direct swapping files through file managers with extended access. Standard MIUI Explorer can hide some system folders, so it is recommended to use MT Manager, Solid Explorer or FX File Explorer.
This is a method that requires care, and you need to find a folder that stores the data of the current theme you've applied. Android/data/com.android.thememanager/files/.miui_themes/ (The path may vary depending on the Android version and MIUI). Inside you will find folders with long names – these are the themes that are set.
If you find an active theme folder, go to the audio or sound directory, and you'll see files with names like lock.mp3, unlock.mp3, or lockscreen.mp3, and you'll rename your pre-made audio file exactly as the original file is called and replace it.
Example of the path to active theme sound files:
/storage/emulated/0/Android/data/com.android.thememanager/files/.miui_themes/[ID_ Topics]/audio/lock.mp3Once you have a file replaced, you need to restart the device, or at least switch the theme to the standard and back again, so that the system can reread resources. MIUI due to increased folder protection Android/data in new versions of Android (11, 12, 13+).

☑️ Checklist before replacing system files
Comparison of methods of customization of sound
The choice of method depends on your version of MIUI, smartphone model and level of training. Below is a table that will help determine the best way to replace the locking sound for your case.
| Method | Difficulty | Security | Demands a PC. | It works on Android 13+. |
|---|---|---|---|---|
| Official themes | Low. | Tall. | No. | Yes. |
| Topics editor (PC) | Medium | Tall. | Yes. | Yes. |
| File manager | Tall. | Medium | No. | Partially. |
| Root rights | Very high. | Low. | No. | Yes. |
As you can see from the table, most users are left with official tools or themes editors on their PCs, and the file manager method is becoming less relevant due to Google’s security policies being implemented in new versions of Android.
Root rights give full access, but are not warranty-free and can disrupt Google Pay (Mir Pay) banking applications and services, so if your goal is just to change the tune, root is not advisable.
⚠️ Warning: Installing themes from unknown sources (.mtz files) can be risky. Always check files with antivirus and download themes only from trusted forums or official stores.
Solving Common Problems and FAQs
In customization, users often face a number of common problems, such as the sound may not change after replacing a file, in which case check the file format: the system can ignore files with an unsupported codec, even if the mp3 extension is used.
Another common problem is that the sound is played back, but very quietly, because the original file was written at a low volume. Edit the file to increase the gain (gain), but make sure that there are no wheezing.
Why did the sound drop after the MIUI update?
If you used the file method and saw the standard sound after the reboot, the system recovered the original file from the secure cache, in which case try the theme-constructor method, which integrates deeper into the design system.
💡
The most stable result on modern versions of MIUI is the creation of your own theme with a replaced audio file, rather than direct editing of files in memory.
Remember that on different models (Redmi Note, Poco F, Xiaomi Mi), the path to files may be slightly different.
