Personalizing a smartphone is the first step towards creating a comfortable digital environment, and replacing the standard monotonous ringtone with your favorite song is one of the most popular actions among users. Owners of a popular model Redmi 9working on a shell MIUIare often faced with interface nuances that distinguish their devices from a “pure” Android. Understanding these differences allows you not only to change the sound, but also to competently manage the audio streams of the device.
The process of setting a melody may seem confusing due to aggressive system optimization and file system features, however, following a clear algorithm, you can set up incoming calls in a couple of minutes. It's important to consider that system restrictions may hide some audio files from the standard selection, requiring additional methods, which we'll detail below. A deep dive into sound settings will allow you to avoid common mistakes and enjoy individual sound.
Preparing an audio file and checking the format
Before proceeding with system settings, you need to make sure that your audio file is technically compatible with the smartphone operating system. Redmi 9like most modern devices based on Android, natively supports formats MP3, M4A and WAV. If your music is stored in rare or protected formats, the system may ignore the file when trying to install it on a call, so converting to a universal one is the most reliable solution. The location of the file in the device memory plays a critical role, since the shell has strict rules for accessing media content. For successful installation, it is recommended to move the music track to the root folder MP3 is the most reliable solution.
The location of the file in the device memory plays a critical role, since the shell MIUI has strict rules for accessing media content. For successful installation, it is recommended to move the music track to the root folder Music or Ringtones internal storage, and not store it deep in downloads or messenger folders. This will simplify the search for a song and ensure that the system player can correctly read the track metadata.
For the best sound quality, choose files with a bitrate of at least 192 kbps, as the difference will be noticeable on the Redmi 9 speakers.
Pay attention to the track duration: songs that are too long may be cut off by the system or played incorrectly when a call arrives. The optimal duration of a ringtone is from 15 to 30 seconds, which allows you to hear the beginning of the melody and identify the caller without tiring your ears with repeated fragments.
Installing a system melody through the settings
The easiest and most reliable way to change the sound of an incoming call is to use the built-in capabilities of the operating system, without resorting to third-party software. This method guarantees stable operation and no conflicts with security updates. To get to the desired menu, you need to follow the path: Settings → Sound and vibration → Phone ringtone.
In the list that opens, you will see a set of preset melodies that were downloaded by the manufacturer. The peculiarity MIUI is that exclusive tracks are often available here, optimized specifically for the speakers of devices Xiaomi and Redmi. Selecting system audio is the quickest way to ensure compatibility, since these files already have the correct encoding and duration.

After selecting the melody, the system will immediately apply the changes and you will hear test playback. It is important to note that some firmware versions may require an additional download of the sound package via Wi-Fiif the selected ringtone is marked with a cloud icon. This is normal practice to save the device's built-in memory.
How to put your own track on a call
Installing your own music requires several additional steps, since custom files are not displayed in the general list of system ringtones by default. You will need to open the sound selection menu as described in the previous section and scroll to the bottom of the list. There you will find a button + or item Select a melody on the devicethat launches the system file manager.
Navigation through the file system in MIUI may differ from the usual one Android, so be careful. You need to find the folder where you previously saved the prepared audio file (usually this Music, Download or MIUI/sound). After selecting the file, the system will copy it to a special directory of ringtones and add it to the list of ringtones available for installation.
⚠️ Attention: If after selecting the file the call is not installed, check the access rights of the Explorer or Music application to the file system in the privacy settings.
There is also an alternative method through the app Themes, which is preinstalled on all smartphones Redmi. In the section Profile → Ringtone you can load a track from the device memory, which sometimes works more stable than the standard sound settings menu, especially on older versions MIUI 12.
☑️ Checking the track installation
Setting up individual sound for contacts
One of the most useful personalization features is the ability to assign a unique ringtone for a specific subscriber. This allows you to determine the importance of a call without looking at the screen, which is especially important during meetings or work. To implement this function, you need to open the application Contact or Phone and go to the card of the desired person.
In the contact card, find the button Edit (usually a pencil icon or three dots in the corner). In the menu that opens, scroll down to Melody or Ringtone. By clicking on it, you will be taken to the same sound selection menu, where you can assign both a system track and a previously downloaded custom song specifically for this subscriber.
| Option | General ringtone | Contact ringtone | Do not disturb mode |
|---|---|---|---|
| Priority | Low | High | Locked |
| Volume | General | General | 0 dB |
| Vibration | Standard | Individual | Disabled |
| Duration | Full | Full | - |
It is worth considering that if you delete a contact from the phone book, the individual melody assigned to it will also be lost, and calls from this number will be accompanied by a general sound. Therefore, before clearing the phone book, it is recommended to back up your contacts through your account Google or Mi Account.
Using the Themes application to download sounds
The Theme Store MIUI is a powerful tool that is often underestimated by ordinary users, limiting themselves only to changing the wallpaper. However, this is where there is an extensive library of free and paid ringtones that are automatically integrated into the system. To access this resource, open the application Themes and switch to the tab Sounds or find the corresponding section in the profile menu.
The advantage of using the built-in theme store is content optimization: all tracks are tested for hardware compatibility Redmi 9 and will not cause playback errors. In addition, here you can find popular sound effects from games, films and viral videos, which are difficult to find in good quality in the public domain.
Secrets of the theme store
The theme store often holds promotions when paid ringtone packages become free. Follow the “Free” banner on the main page of the sounds section.
After downloading your favorite sound package through the app Topics, they will automatically appear in the standard ringtone selection menu in the sound settings. You will not need to perform any additional actions to move files, since the system itself will register new audio files in the media registry.
Solving problems with volume and playback
A common problem for users Redmi 9 is the sound of the call is quiet or completely absence, even when the volume slider is turned to maximum. This may be due to the operation of the function Audio Enhancer or a conflict between Bluetooth devices. First, make sure that in the sound settings (Settings → Sound and vibration → Advanced sound settings) any surround sound effects that can distort the call signal are turned off.
It is also worth checking if the “Pocket” or “In Pocket” mode is activated, which can block speaker under certain conditions. If the phone is lying on a soft surface, the proximity sensor may block the sound, in which case regular cleaning of the top of the screen or disabling this function in the menu Pocket lock.
⚠️ Attention: The settings menu interface may vary slightly depending on the version of MIUI (12, 12.5, 13). If you don’t find the item, try searching in the settings by typing in the word “ringtone.”
If the sound appears with a delay after pressing the call button on another phone, the problem may lie in the audio file format. Heavy files without compression (for example, FLAC or WAV high resolution) require time to decode by the processor, which creates the effect of “silence” in the first seconds of the call. Converting to MP3 128-320 kbps solves this problem instantly.
The optimal format for a ringtone on Redmi 9 is MP3 with a bitrate of 192 kbps, providing a balance between quality and system response speed.
