Smartphone personalization is not just a matter of aesthetics, but also an important aspect of the ergonomics of using the device. When the Xiaomi Redmi Note 9 is lying on a table in a bag or on a desk in a noisy office, it is a unique beep that helps instantly identify an incoming call without taking out the gadget. Standard tunes pre-installed by the manufacturer are often too quiet or banal, which leads many users to look for ways to replace them immediately after buying.
With MIUI, which is installed on the Redmi Note 9, the ringtone change process can seem confusing due to localization and menu structure. The shell interface hides some features in non-obvious places, and the standard file manager does not display the folder with system sounds by default. However, with the precise navigation paths and some technical nuances, you can easily customize the individual sound for any event.
In this article, we will discuss in detail all available methods for installing new compositions: from choosing a track from the built-in library to using your own tracks. MP3-We will also address the issues of vibration adjustment and solving the typical problems when the phone “cannot see” audio files. For the user ringtones to work correctly on the Redmi Note 9, the file must be in the format of the audio file. MP3 or OGG and have a bitrate not lower than 128 kbit / s.
Preparation of audio files and search for built-in melodies
Before you start setting up, you need to decide on the source of the sound. owners of Redmi Note 9 can choose from a rich built-in collection or download their own tracks. Xiaomi System Library offers a lot of quality compositions, divided by genres, which eliminates the need to search for files on the Internet, to view them, just go to the audio settings.
If you prefer to listen to your music, you will need to download a file in.mp3 or.ogg format to your device. Simply putting a file in the root of memory or in the Downloads folder is often not enough to appear in the list of available ringtones.
To properly display the composition in the call selection menu, the file must be moved to a special directory. You can use the built-in Explorer app or a third-party file manager, such as Total Commander or Files by Google.
- 🎵 Download the desired melody from a reliable source or copy from your computer through a computer. USB-cable.
- 📂 Create a folder called Ringtones (for calls) or Notifications (for calls) SMS) The root of the inner memory, if they are not there.
- 📁 Move the downloaded audio file to the created folder so that the system indexes it as system sound.
- 🔊 Make sure the file is not copyrighted DRM, Otherwise, it will not be played as a call.
⚠️ Note: Do not try to rename system files in the folder /system/media/audio/ringtones without superuser rights (Root), this can lead to errors in the interface MIUI.
After moving the file, you may need to restart the smartphone or wait a few minutes for the system media scanner to update the database. In some cases, if the track does not appear immediately, you can use the File Manager app, find the file, click on it and select "Install as a ringtone" in the context menu.
Set the ringtone through standard settings
The most reliable and correct way to change the incoming call sound on the Xiaomi Redmi Note 9 is to use the standard settings menu.This method ensures that the volume and playback settings are applied correctly for all SIM cards. The interface may vary slightly depending on the version of MIUI (11, 12 or 13), but the logic remains the same.
To start, unlock the screen and find the Settings icon. You're interested in a section that might be called Sound and Vibration or just Sound. This menu contains all the options associated with the device's audio alerts, and you can adjust not only the melody, but also the vibration intensity.
On the audio settings screen, you'll see "Calling Melody" or "Calling Melody," and clicking on it will open a list of available songs, and if you've done the steps from the previous section correctly, your personal files will be at the top of the list or in a separate tab called "Locals."
☑️ Algorithm of setting a call
When you select a song you like, the system automatically applies it, and you'll hear a short preview track, and note that two-symbol models like the Redmi Note 9 can set different tunes for the SIM 1 and SIM 2, which is very convenient for separating work and personal contacts.
💡
Use the Vibration Call feature in the same menu to not only make the phone sound, but also vibrate in rhythm, which is useful in noisy places.
Customization of individual melodies for contacts
One of the most useful features in the Xiaomi Redmi Note 9 arsenal is the ability to assign a unique ringtone to a specific subscriber, which allows you to know who is calling without even looking at the screen, just by sound, a feature that is especially relevant for important contacts, from which you should not miss a call in any case.
The process of customizing your individual sound is a little different from the global melody change: you need to open the Contacts or Phone app and find the desired entry in the phone book. Once you open the contact card, you should click on the Change button (usually a pencil icon) or find the Add Field option if the desired option is not on the card's home screen.
In the editing menu, find the line "Melody" or "Rington"; by default, it's "Default" or "Like on the phone." By clicking on this line, you'll be taken to the same track selection menu as in the general settings, where you can select any track from the list or download a new one.
- 👤 Open the contact you want to assign a unique sound to.
- ✏️ Press the edit button (pencil) or the button "More" (three dots).
- 🔊 Select the item "Melody" and specify the desired audio file.
- 💾 Save the changes by clicking the tick or the “Done” button».
It is worth noting that if a contact is synced to a Google account, the setting can only apply to that device or, conversely, spread to all devices if profile sync is used. In most cases, the settings are stored locally in the Redmi Note 9 memory.
⚠️ Note: If you change a contact's phone number or create a duplicate record, the individual melody may reset.

Change the sounds of SMS notifications and applications
Sound navigation is important not only for calls, but also for messages. On the Xiaomi Redmi Note 9, you can flexibly adjust the sound for SMS, messaging (if they support system notifications) and system events, which helps to instantly distinguish an important message from an advertising mailing.
To change the sound of the SMS, you need to go back to the Settings → Sound and Vibration menu. You need to find the Notifications or Notification Sound. The principle of operation is similar to setting a call: you select a track from a list or download your own by pre-placing it in the Notifications folder in internal memory.
Special attention should be paid to the settings inside the messenger apps themselves, such as WhatsApp, Telegram or Viber. Although they often use their own sounds, they can be redefined through the Android system settings. To do this, find the Notifications section in the app settings and select Sound. If you choose Default, the system sound we just set up will play.
| Type of event | Path in settings | File folder | File format |
|---|---|---|---|
| Incoming challenge | Sound and vibration → Phone call | /Ringtones | MP3, OGG |
| SMS message | Sound and vibrations → Notifications | /Notifications | MP3, OGG, WAV |
| Alarm clock | The clock → Settings of alarm clock | Any available | MP3 |
| Systemic sounds | Sound and vibration → Additionally. | Systemic | OGG |
Sometimes users are faced with a situation where the notification sound is there, but it is very quiet.This may be due to a separate volume slider.In the Sound and Vibration menu, click on the gear or arrow next to the slider to expand the settings, and make sure the volume of the notifications is twisted to the maximum.
Setting up the alarm clock and timer
Waking up to nice music is a great way to start the day. The standard alarm clock on the Redmi Note 9 can get boring or too sharp. Fortunately, the Clock app lets you use any song from your library as a wake-up call.
Open the Watch app and go to the alarm tab. Click on your existing alarm clock to edit or create a new one. In the time settings menu, you'll see "Sound" or "Melody." Click on it and you'll be taken to the system's built-in music player, which has access to all the audio files on the device.
You can choose a track from the Mi Cloud if you use Xiaomi services, or find a file in your phone's memory. The MIUI feature is the ability to select a specific minute to start playing the track, allowing you to enter and start the alarm immediately from the chorus.
💡
Use the “Increasing Volume” function in the alarm settings so as not to wake up abruptly from a loud sound, but to smoothly leave your sleep.
Be sure to check the alarm clock by setting it a minute ahead in test mode. Also make sure the phone isn't in "Do Not Disturb" or "No Sound" mode at the scheduled time, although modern versions of Android usually ignore the silent alarm mode.
The Solution: Why the Melody Doesn't Work
Despite the ease of customization, users of the Xiaomi Redmi Note 9 sometimes face problems: the melody does not set, the standard horn is played or the sound is interrupted, most often the reason lies in file formats or application access rights.
One common reason is unsupported audio. While MP3 is a universal standard, some codecs inside an MP3 container may not be readable by the ringtone system player, and problems may arise with high-resolution (Hi-Res) files, which are designed for Hi-Fi listening rather than system signals.
Another common problem is the failure of the application “Themes” or “Sounds”, which in MIUI are often related. If the standard menu does not allow you to choose a file, try to install the melody through the application “Themes” (the “Sounds” section at the bottom of the screen), which is a deeper level of interface customization.
- 📉 Check the bitrate of the file: it should not be too high (above 320 kbps can cause errors).
- 🔒 Make sure that the Phone and Contacts app are given permissions to access the device’s memory.
- 🔄 Clear the cache of the Sounds app in the Apps section» → «All applications».
- 📂 Check if the file is hidden in a folder that starts with a dot (such as.music) because the folders are hidden from the system.
⚠️ Note: After the firmware update MIUI You can reset your sounds to the factory.
If nothing helps, try restarting your smartphone to Safe Mode to eliminate the impact of third-party equalizer apps or amplifiers that can intercept the audio stream.
