Xiaomi’s Redmi 9 lineup is rightly considered one of the most popular budget devices on the market. They offer excellent value for money, as well as a powerful MIUI shell that provides the user with extensive personalization options. One of the key aspects of comfort when using the gadget is the sound, in particular, the wake-up signal. Standard ringtones preinstalled by the manufacturer often seem monotonous or annoying, so many owners are eager to replace them with their favorite music compositions.
But the process of installing your own audio file on an alarm clock in the MIUI interface is not always obvious to beginners. The system has its own features of navigation and file management, which can confuse those who move from other operating systems or simpler button phones. In this article, we will analyze all the nuances of the settings so that you can wake up to the sounds of your favorite music without unnecessary complications.
There are several ways to solve this problem, from standard system settings to the use of third-party applications. We will look at each of them, paying special attention to possible errors and their solutions. Redmi 9 is equipped with a sufficiently powerful multimedia module, so the correctly tuned sound of the alarm clock will sound high-quality and loud, ensuring that you do not miss the important event.
Preparation of an audio file for installation
Before you start setting up in the menu of the smartphone, you need to make sure that the audio file is properly loaded into the memory of the device. MIUI, requires files to be in certain directories for their correct display in the selection list. Most often, users download music from the Internet or receive through instant messengers, and the files are placed in the Download folder or Telegram/Audio.
For ease of working with the system settings of the alarm, it is recommended to move the desired track to the standard Ringtones or Alarms folder. This is not a strictly mandatory requirement for all versions of the firmware, but greatly simplifies the search for composition in the list that opens when you set up the signal. If the file lies deep in the messenger folders, the standard alarm player may simply not see it.
Use the built-in MIUI file manager or any other explorer to perform this operation. Find the downloaded track, click on it and select the Move or Copy function, and then specify the target folder in internal memory. Make sure the file format is compatible; MP3 is the best choice, although current versions of Android support both AAC and WAV.
⚠️ Warning: Make sure the audio file is not protected DRM-Music downloaded from offline streaming services (e.g. Yandex.Music or Spotify) often has special extensions and cannot be used as a system ringtone without removing protection.
Where can I find hidden folders in MIUI?
Installation of the melody through the standard app “Clock”
The most direct and reliable way to change the wake-up sound on Redmi 9 is to use the built-in Clock app, which ensures that the setting applies to the specific alarm clock you use. Open the app, which usually has a timer or clock icon, and go to the alarm control tab.
You'll see all the alarm clocks you've created on the list, click on the alarm clock you want, or create a new alarm clock by tapping the plus sign. In the settings menu that opens, find the item that controls the sound. In different versions of MIUI, it can be called "Sound," "Melody" or "Rington," and by default, it will be a standard Xiaomi composition.
Clicking on this, you'll be taken to the melody selection menu. At the top of the screen, there's often tabs like "Everything," "Music," "Sound Manager." Select the "Music" or "Everything" tab to scan the memory of the device. Find your track in the list and click on it to confirm the selection. Now, when the alarm goes off, this particular composition will play.
☑️ Checking alarm clock settings
If you use multiple wake-up signals (e.g., separately for work days and weekends), you will need to repeat the procedure for choosing a tune for each of them separately, which allows you to flexibly customize wake-up scenarios.
Configure through the system menu of sounds
An alternative way is through the general settings of your smartphone, which is convenient if you want to set a single default tune for all future alarm clocks, or if the Clock interface is not available for some reason. Go to the main settings menu of Redmi 9, touching the gear.
In the settings list, look for the Sounds and Vibrations section, which contains all the audio settings of the device, scroll down to the alarm clock, and click on it, and the standard melody selection menu, similar to what we looked at in the Watch app, will open.
Select the sound source, "Music on the device" or "Sound Manager." The system will offer a list of available tracks. Once selected, the composition will be set as the main alarm signal, which is especially useful if the Clock application has been removed or damaged, since the settings are stored at the system level.
| Parameter | Description | Recommended value |
|---|---|---|
| Loudness of alarm clock | Sound level upon activation | 100% (maximum) |
| Vibration. | Duplication of sound by vibration | Included. |
| Repeat. | Signal repetition interval | Every minute. |
| Attenuation | Smooth volume build-up | 10-15 seconds |
💡
Use the "Attenuation" feature to wake up softer. A sharp start of loud music at maximum volume can cause stress in the morning.
Work with volume and profile "Do not disturb"
One of the most common problems Redmi 9 users have is the quiet sound of an alarm clock or its complete absence at a certain time.This is often due to separate volume control in Android. Media volume, bell and alarm clock are three different parameters. Make sure the alarm clock volume slider is twisted to maximum.
Also critical is Do Not Disturb. In some MIUI configurations, this mode can block the alarm unless exceptions are set up. Go to the sound settings and check if the silent mode is activated. If so, it should tick "Allow alarms" in its settings.
The physical volume buttons on the side of the smartphone are the default to adjust the volume of the media or bell. To change the volume of the alarm clock, press the volume button and tap the tripod or arrow down to turn the full mixer.
⚠️ Attention: If you use a Bluetooth headset or speaker, check the audio output settings. The alarm clock may try to play the sound through a disabled Bluetooth device, causing the smartphone speaker to be silent. In the alarm settings, make sure that the sound is coming through the phone speaker.
Use of third-party alarm clock applications
If Xiaomi’s standard tools don’t seem functional enough, Google Play offers a variety of alternatives, apps like Alarmy, Sleep Cycle, or Timely provide advanced audio management capabilities, and allow you to use any song from your library, even if it’s not moved to your system folders.
Third-party apps often have access to online music libraries, allowing them to set alarm clocks that are not in the phone’s memory, and they can offer smart wake-up features by analyzing sleep phases, or require tasks (shake the phone, solve an example) to turn off the sound.
When installing an app on Redmi 9, it is important to give it all the necessary permissions. MIUI aggressively saves battery power and can kill the alarm process in the background. Go to the application settings, find Activity Control or Battery, and select No Limits mode.
This ensures that even if the screen is off and the phone is in your pocket, the app can start the sound at the designated time. Without this permission, the alarm may simply fail to work, showing a missed time notification after the fact.
💡
Third-party apps give more freedom in the selection of tracks, but require careful adjustment of permissions in MIUI so that the system does not block their operation in the background.
Addressing common problems
Despite the simplicity of the procedure, users may encounter difficulties, such as the phone is silent, although the alarm is set, check if the flight mode is on in combination with energy saving settings, which can turn off communication and sound modules at night (although the alarm should work without the network).
Another problem is that the wrong track is played or the file is damaged. If the music breaks or wheezes, try converting the file to a more standard MP3 format with a bitrate of 128 or 320 kbit / s. Too high audio quality (Lossless) can put a strain on the processor when decoding at the time of waking.
Also worth checking out is system updates. Xiaomi regularly releases security patches and improvements for MIUI that can fix sound bugs. Go to Settings → About Phone → MIUI version and check for updates.
