Changing the standard ringtone is the first step to personalizing your Xiaomi Redmi 9C, which allows you to instantly recognize an incoming call among many other devices. Smartphone owners often face the desire to replace the monotonous system sound with a favorite song or a unique audio file downloaded from the Internet. The process of installing a new tune in the shell of MIUI (or its more recent versions of HyperOS) has its own nuances that distinguish it from “pure” Android, but it remains quite simple with clear instructions.
In this article, we will discuss in detail all available ways to customize the soundtrack: from selecting a track from the built-in library to installing your own. MP3-It is important to understand that the correct configuration of audio files requires compliance with certain formats and place the files in the corresponding memory folders so that the system recognizes them correctly. We will look at the typical errors when the phone “does not see” the track, and methods for quickly eliminating them without using third-party software.
Before you start taking action, make sure your Redmi 9C has access to the storage where the desired composition lies.If you plan to use online services to download music, check the stability of the internet connection. Xiaomi system ringtones are protected from removal, but custom tracks can be accidentally deleted when clearing the cache if they are in system folders, so store the music in the Music or Download folder. Next, we will move to direct audio setting through the device menu.
Preparation of audio files and support formats
The first step in the audio profile customization process is to prepare the file itself. Xiaomi smartphones support a wide range of audio formats, however, to ensure maximum compatibility and correct playback as a call, it is best to use MP3, M4A or WAV formats. These formats ensure that the melody will play immediately after the call arrives without decoding delays, which is especially important for budget models such as the Redmi 9C.
If you download music from the Internet, pay attention to the bitrate of the track. Too high quality (for example, Lossless FLAC) may not be supported by a standard caller, and the file simply does not appear in the list of available tunes. The optimal choice is MP3 with a bitrate of 128 to 320 kbit / s. Also worth considering the duration of the track: for a call, it is better to choose a 15-30-second segment so as not to wait for the end of the long introductory part of the song while you pick up the phone.
⚠️ Attention: Files protected DRM (Digital rights, such as tracks from subscriptions to some streaming services, cannot be set as a ringtone.
To place files, use the device's internal memory. After downloading, move the audio file to a folder called Ringtones (for calls) or Notifications (for notifications). This is not strictly mandatory in newer versions of MIUI, since the system can scan all memory, but folder sorting makes it much easier to find the desired track in the shared list. If there is no Ringtones folder, create it manually through any file manager.

Use a built-in voice recorder to create a unique ringtone from a voice or ambient sound, and then trim it in the Sound Recording app before installation.
Installation of the melody through standard settings
The most common and reliable way to change the sound of an incoming call is to use the regular system settings menu, which requires no additional applications to be installed and works consistently on any firmware version. To get started, open the Settings app on the home screen or in the notification curtain. Find the audio section that handles the sound, which in different versions of the shell can be called "Sound and Vibration" or simply "Sound".
Inside the audio menu, you need to find the "Call Melody" or "Rington" item, and if you click on it, you'll see the list of available songs. Here you'll see the standard tunes from Xiaomi and Google. To select a custom track, scroll down the list and click on the "Choice Melody on Device" or the plus icon. The system will suggest you choose the source: file manager or music player.
- 🎵 Open Settings and go to the section "Sound and vibration».
- 📞 Click on the "Call Melody" item to select the main ringtone.
- 📂 In the window that opens, select “Select a melody on the device».
- 🎧 Find the desired file in memory and confirm the selection with the “OK” button».
Once you select a track, the system will automatically apply the changes. You can immediately check the result by making a test call from another number. If the sound hasn't changed, try restarting the device. Rebooting often helps the system re-index media files and correctly pick up new audio settings. You can also set the vibration and volume of the call in this menu to ensure that the personalization is complete.

Using the Themes app to upload sounds
A unique feature of Xiaomi’s ecosystem is the Themes app, which allows you to download not only wallpaper and fonts, but also entire packs of ringtones. It’s a convenient way to find quality, already cropped and processed tracks created specifically for smartphones. The app has a separate category “Melodies”, which collects thousands of options from independent authors.
To work with this method, launch the Themes app and switch to the Melodies tab at the bottom menu. Here you can listen to a preview of the tracks. If you like a song, click the download button (shooting down) and then the Apply button. The system automatically sets the selected track to the call, and the advantage of this method is that you don't have to search for files on the Internet and worry about formats.
However, it’s worth remembering that many premium tunes in the theme store can be paid or subscription-based.The free content is also extensive but takes time to search.Themes app can sometimes offer you to set up whole themes along with the melody, be careful when you click the “Apply” button so as not to change the entire interface of the phone if you only need sound.
How to remove downloaded melodies?
Set up an individual call for contact
Often, you need to hear a call from a particular person to keep an important conversation in mind, even if the phone is silent for others. Redmi 9C has a convenient feature for assigning a personal ringtone to each contact from the phone book, which allows you to instantly respond to calls from loved ones or colleagues.
To set up, open the Contacts or Phone app and go to the Contacts tab. Find the person you want and open the card with the details. At the top of the screen or in the menu (three dots in the corner), find the Sound or Call Melody option. When you click on it, you will be placed in the same track selection menu as in the general settings, but the action will only apply to that subscriber.
| Action. | Where to find out. | The result |
|---|---|---|
| Opening of contact | Annex “Contacts” | Subscriber card |
| Choosing sound | The "Sound" button in the card | A list of tunes |
| Application | Pressing OK | Individual call set up |
| Verification | Test challenge | Sound is different from the general sound. |
If you don't see "Sound" in your contact card, click on the edit button (pencil) or three dots in the top right corner of the screen. In some versions of MIUI, this option is hidden in the optional menu. The appointment of an individual call works even if the phone's general profile is in "No Sound" mode, unless the "Do Not Disturb" setting has an exception for contacts. Important: if the contact is removed, the individual ringtone will also disappear.
Solving Display and Reproduction Problems
It's not uncommon for users to have a file downloaded that doesn't show up in the list of available tunes or is played with distortions. The most common reason is the path to the file. Android and the MIUI shell scan the media storage, and if the file is in a hidden folder or a name folder that starts from a dot, it will be ignored. Move the file to the root of internal memory or to the Music folder.
Another common problem is a broken file or an unsupported codec. Even if the file extension is.mp3, sound can be encoded inside in a format that the standard call player does not understand. Try playing the file through a third-party player (such as a VLC or MX Player). If it does not play there, the file is corrupted. If it plays but is not put on a call, try converting it to a more standard format through online converters.
⚠️ Note: Do not use files with a bitrate above 320 kbps or a sampling rate above 48 kHz for calls, as Redmi processor 9C may not have time to decode them at the time of the incoming call, and the call will pass without sound.
Also check the permissions of the Themes or Sounds app if you use them to select. Go to Settings → Apps → All Apps → Sounds (or Themes) → Permissions and make sure that access to memory (files and media) is allowed. Without this right, the system will not physically be able to "see" your music files. Resetting the settings of the audio application often solves the problem of hanging the list of tunes.
Additional settings of sound profiles
In addition to selecting the melody itself, the Xiaomi Redmi 9C has a wide range of audio behavior settings available. You can adjust the sound amplification in your pocket to make the phone ring louder when it is in your bag. This feature is located in the Settings menu → Sound and vibration → Amplification of sound in your pocket. This is useful if you often miss calls due to a quiet ringtone in noisy places.
And you can also use the "Ring Vibration" feature, which you can synchronize with the rhythm of the melody, or you can adjust your own vibration pattern, and in the ringtone selection menu, click on the setting icon (cog) next to the volume slider or at the top of the screen, and you can create a unique vibration that feels tactile with the sound signal, which increases the likelihood of noticing the incoming call.
Don't forget the sound profiles. In MIUI, you can quickly switch between General, No Sound and Vibration Only modes through the notification curtain or side control panel. The flexibility of the settings allows you to create the perfect balance between the visibility of the call and the comfort of the surroundings. Experiment with the combinations of media volume, alarm and call to find the perfect sound for your Redmi 9C.

Properly placing files in the Ringtones folder ensures they are displayed in the list even after the phone is rebooted and interface settings are reset.
