You downloaded your favorite song, try to put it on the phone in Xiaomi Redmi 9A, but the system stubbornly ignores your actions? The melody is not saved, the standard signal returns or disappears from the list of available ringtones? This problem is familiar to many owners of budget Xiaomi smartphones, especially after the MIUI updates. In 80% of cases, it is not the fault, but the manufacturer’s software restrictions or incorrect settings.
In this article, we’ll look at all the possible reasons why the Redmi 9A doesn’t install a ringtone, from the banal lack of rights to hidden MIUI features that aren’t written about in the official instructions. You’ll get step-by-step solutions for each situation, including bypassing system locks without root rights. And in the end, a proven way to add any audio file to the ringtone list, even if the smartphone doesn’t see it.
1. Checking the basic conditions: file format and storage folder
Before digging deeper, make sure your audio file is MIUI compliant. Xiaomi Redmi 9A only supports ringtones in certain formats and folders – this is the first thing that blocks installation.
Permissible formats for ringtones:
- 🎵 MP3 (recommended, bitrate up to 320 kbit/s)
- 🎵 M4A (AAC, without DRM-defense)
- 🎵 WAV (without compression, but takes up a lot of space)
- ❌ FLAC, OGG, WMA — Not supported like ringtones
Where the file should be:
- 📁 /storage/emulated/0/Ringtones/ — ringtone
- 📁 /storage/emulated/0/Notifications/ — quiz
- 📁 /storage/emulated/0/Alarms/ — alarm-box
💡
If you don't have a folder, create it manually through any file manager (e.g. Files by Google or Mi File Manager).
How to check the file format:
- Open the file properties (long press). → «Information" or "Properties»).
- Watch the extension (e.g. song.mp3).
- If the format is not suitable, convert via Online-Convert or Audacity.
MIUI Limitations: Why Your Smartphone Can't "See" Your File
Xiaomi artificially restricts the selection of ringtones in Redmi 9A through the proprietary shell MIUI. Even if the file is in the correct folder and has a supported format, the system can ignore it.
| Reason for limitation | How it manifests | Decision |
|---|---|---|
| Duration filter | Files longer than 30 seconds are not displayed | Cut in an audio editor |
| Size limitation | >5 MB files are not added | Compress the bitrate to 192 kbit/s |
| Blocking “non-system” files | The file is in the folder, but not visible in the settings | Move to /system/media/audio/ringtones (root) |
| Cash media libraries | Changes do not apply after adding a file | Reboot your phone or clear the cache com.android.providers.media |
The most common case is that MIUI does not update the media base after adding a new file.
- Go to Settings → Applications → Application Management.
- Find a media store (or media store).
- Click Clear the cache and Clear the data.
- Reboot your smartphone.
What if files are missing from the gallery after cleaning the cache?
Access rights issues: why the system is blocking the installation
Android 10/11 (and Redmi 9A works on them) has strict restrictions on access to files, and if you downloaded the ringtone through a browser or messenger, the system can block its use as an “unsafe” file.
How to check your rights:
- 🔒 Open the Settings. → Annexes → Permits → Warehouse.
- 🔒 Make sure the app you downloaded the file from (such as Chrome or Telegram) has access to the storage.
- 🔒 Check if the icon is displayed next to the file 🛡️ (means limited access).
If the file is downloaded from the Internet:
⚠️ Attention: MIUI By default, you block the installation of ringtones from downloads. Move the file from the Download folder to Ringtones manually, and that will remove the restriction.
An alternative way is to use a root-access file manager (e.g., FX File Explorer):
- Open the manager and find your audio file.
- Long press → Properties → Change permissions.
- Set check boxes for Reading and Write for all users.
- Save the changes and restart the phone.
4. Application conflicts: what prevents the installation of ringtones
Sometimes the problem is not the system, but the third-party software, and especially often conflicts are caused by:
- 🎵 Sound customization apps (such as Zedge or Ringtone Maker).
- 🛡️ Antiviruses (Avast, 360 Security) that block access to files.
- 🔄 Clean Masters that remove “unnecessary” media files.
- 📱 Launchers (such as Nova Launcher) that intercept audio settings.
How to diagnose the problem:
- Start the phone in Safe Mode (click the Shutdown button → Safe Mode).
- Try to set the ringtone again.
- If it works, it is one of the third-party applications that is to blame.
What to do next:
- 🔍 Turn off applications from the list above (in Settings) → Annexes).
- 🔄 After turning off each, check if it is possible to install the ringtone.
- 🗑️ Remove the conflicting app or reset its settings.
Delete the Zedge cache or analogues |
Disable the antivirus for 5 minutes |

5.Resetting sound settings: a radical solution
If all previous methods failed, the problem may lie in damaged audio profile settings, and MIUI has a hidden feature that resets audio settings to factory settings, which often helps to restore the ability to set ringtones.
How to perform the reset:
- Go to Settings. → Sound and vibration.
- Slip on the three points in the upper right corner (or additionally).
- Select Reset sound settings (or Reset sound settings).
- Confirm the action and restart the phone.
⚠️ Warning: This method will reset all audio settings, including alarm clock volume, notifications and media.Write down current volume levels before resetting!
If the Reset audio settings item is not in the menu, use an alternative method through the Recovery mode:
- Turn off the phone.
- Press Power + Volume Up to Enter Recovery.
- Choose Wipe & Reset → Reset settings (not Wipe data!).
- Confirm and wait for the reboot.
6.Manual addition of ringtones via ADB (for advanced)
If MIUI persistently ignores your file despite all the manipulations, it is left to add directly to the system folder via ADB. This method works even when standard methods are powerless, but requires a connection to a computer.
What you need:
- 🖥️ Computer with Windows/Mac/Linux.
- 🔌 USB Type C C Cable (original!).
- 🛠️ Utility. ADB (download from the official website).
- 📱 Included debugging by USB phone-on.
Step-by-step:
- Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version. Go back to Settings → Additional → Developer. Turn on USB Debugging.
Connect your phone to your PC and confirm your trust in the device.

ADB
adb devices
adb shell
su
mount -o rw,remount /system
cp /sdcard/Ringtones/your_ringtone.mp3 /system/media/audio/ringtones/
chmod 644 /system/media/audio/ringtones/your_ringtone.mp3
rebootyour_ringtone.mp3
⚠️ Attention: Misuse of the right ADB This may cause data loss or system failure. Follow the instructions accurately and do not change other system files!
💡
If the ringtone does not appear in the list after the reboot, check the path to the file with the command ls /system/media/audio/ringtones/.
7. Alternative methods: circumvention of MIUI restrictions
If standard methods don’t work and ADB is too complicated, use the following workarounds:
Method 1: Use a third-party application
- 📱 Install Ringtone Maker or Zedge from Google Play.
