Smartphone personalization is not just a matter of aesthetics, but an important aspect of ergonomics of interaction with the device. Standard tunes preinstalled in the factory often merge into a single noise background, and the user can miss a really important message. Owners of Xiaomi, Redmi and POCO devices have ample opportunities to customize the sound profile, but the interface of the shell MIUI or HyperOS can hide some nuances.
Changing the ringtone allows you to instantly identify the source of the signal, even without taking the gadget out of your pocket, which is especially true in an office setting or when meeting friends, when you need to discreetly understand whether a message came from your boss or just a notification from the game.
In this article, we will explore in detail all the ways to replace audio files, from the banal change of system tone to advanced methods of editing system files, learn how to assign unique sounds to specific contacts and understand why some applications ignore general settings.
Basic configuration of system sounds through the menu
The most obvious and accessible method is to use the built-in settings menu, which may vary slightly depending on the version of the shell, but the logic remains the same: you need to open the Settings app and go to the Sound and Vibration section, and this is where the main levers of control of the device's audio streams are concentrated.
In the menu that opens, you'll see a few categories: volume, vibration, and actually sounds. The system allows you to independently adjust the tone of the bell, alarm, timer and, most of all, the default notifications. When you click on the appropriate item, you'll open a list of preset tunes.
⚠️ Note: Not all preset sounds on the list are full tracks, some are short system signals that can sound annoying when used frequently as a messenger notification.
If the standard set does not suit you, the interface offers a “Download” or “Online themes” button that will redirect you to the theme store. However, this path is not always convenient to install your own file, since it requires authorization and downloading excess content.
Install your audio file as a notification
For those who want uniqueness, the issue of downloading their own MP3 or WAV file is relevant. Unlike ringtones, which often require cropping, short files up to 5-10 seconds are better suited for notifications. Long tracks will break in the middle of a word when a new message arrives.
The process of installing your own file on modern versions of MIUI and HyperOS requires a certain folder structure. Just copying music to the root of the memory is not enough - the system may not see the file in the list of available ones. You need to create or find a MIUI folder at the root of the internal drive, and inside it - a sound folder.
☑️ Preparation of the audio file
After placing the file in the desired directory, return to the Sound and Vibration menu. → Notifications. Scroll down to the bottom, where the Add button should appear or your file will be shared. If the file is not displayed, try restarting the device or clearing the Topics app cache».
💡
Use online services to trim tracks before downloading, so as not to install unnecessary editor apps on your phone.
Individual sounds for different contacts
One of the most useful features in Xiaomi’s arsenal is the ability to assign a unique sound to each (contact), which allows you to know who is texting or calling you without looking at the screen, and this is done through the standard Contacts or Phone app.
Open the contact list, select the person you want, and click Change (usually a pencil icon) and find the Melody or Notification Sound field in the editing menu, and the default is Default, but when you click, you can select any track from the device or system library.
It's worth noting that this setting is often more important than the general settings of messengers. If you have assigned a special sound to contact in the phone book, but WhatsApp itself is "no sound", the notification of the call through the phone book is notified. SIM-The card will still lose the selected track.
| Type of setup | Where applicable | Priority | File format |
|---|---|---|---|
| Systemic sound | All applications without their settings | Low. | MP3, OGG |
| Sound of the app | Specific messenger (Telegram, VK) | Medium. | MP3, OGG |
| Sound of contact | The specific person in the phone book | High-pitched | MP3, OGG |
| Chat sound | Specific correspondence in the messenger | Maximum | Any supportive |
Customization of sounds in popular messengers
Modern communication has shifted to instant messengers, and system settings are often overlaid by internal application rules. Telegram, WhatsApp, Viber and others have their own sound menus that need to be configured separately.
In Telegram, for example, you can set the sound for not only all messages, but also for each chat individually, and also divide the sounds for private messages and groups. To do this, go to Settings → Notifications and Sounds. Here you can select Message Sound and indicate the path to your file.
⚠️ Attention: In Android 11 and above (relevant to the MIUI 12.5/13/14) Access to the file system is limited. If the messenger does not see your file, you may need to give the application permission to access all files in the privacy settings.
On WhatsApp, the situation is similar: Settings → Notifications → Notifications Sound. It is important to understand that if the app itself selects the “No” option, then no system manipulation will cause the phone to make a sound.
Why doesn’t the sound change in the app?
Advanced Methods: Theme Editor and File Manager
For users who lack standard tools, there is a method using a theme editor, which is built-in but hidden application that allows you to modify system resources, and you can find it by searching for applications by typing in the theme editor.
Inside the editor, select “Locals» → «Sounds. You can import audio files and assign them categories (call, notification, alarm clock), and the good thing about this is that the file is written into the system sound index and made available wherever there is a ringtone selection.
Manual copying path (Root or ADB rights required):
/system/media/audio/notifications/
/data/media/0/MIUI/sound/However, using third-party file managers (such as MiXplorer or Solid Explorer) gives you more flexibility: You can copy a file directly to the system folder if you have root rights, which ensures it appears in the list even after resetting the audio settings.
💡
Using a theme editor is the most reliable way to “register” sound in the system without obtaining root rights, since it works at the user profile level, not the system partition.
Problems and Solutions: Why Sound Doesn’t Work
It's not uncommon for users to have a situation where seemingly all settings are done correctly, but the sound doesn't change or play back, and one of the common reasons is Do Not Disturb or Silent Mode, which can be activated on a schedule.
Check the settings in the Sound and Vibration → Do not disturb. Make sure that there is no automatic activation in your active time. It is also worth checking whether Pocket Mode is enabled in special features, which can silence the sound if the proximity sensor is closed.
- 🔊 Notification volume: a banal but often forgotten slider. Press volume buttons and expand the menu to make sure the notification volume level is not at zero.
- 📂 File format: the system may not support some codecs.Convert the file to a standard MP3 bitrate 128-320 kbps.
- 🔄 Application conflict: Third-party launchers or audio management applications (such as Volume Control) can intercept audio stream control.
If nothing helps, try to remove the problematic Themes app (if the firmware version allows) or update it via GetApps. Sometimes the bugs of the MIUI shell itself are solved only by completely resetting the settings or waiting for a software update.
