Modern Xiaomi and Redmi smartphones are famous for their rich functionality, but built-in speakers do not always cope with the playback of media in noisy environments. Often users are faced with a situation where even on the maximum scale the sound seems quiet, illegible or devoid of bass. This can be caused by the software limitations of regional versions of firmware, hearing security settings or simply the features of the hardware of budget models.
Fortunately, MIUI and its successor HyperOS offer tremendous opportunities to customize audio output. Not only can you spin the slider to the point, but you can also fine-tune frequencies, activate virtual surround sound, or even access a hidden engineering menu to manually boost the signal. In this article, we'll look at all the legal and safe ways to make your device sound more powerful and better.
Basic sound settings in MIUI and HyperOS
Before you go to complex manipulations, you need to make sure that all the standard settings are twisted to the maximum and work correctly. In the shell from Xiaomi, audio stream management is divided into several categories, and it often happens that the volume of media files is twisted, and the system sounds or volume in a particular application is limited.
Go to Settings and select Sound and Vibration. Here you will see individual sliders for call, notifications, alarm clock and most importantly, multimedia. Make sure the Call and Notification Volume Switch is activated if you want these settings. Also check if Pocket Mode is enabled, which can artificially lower the volume of the speaker under certain conditions.
Special attention should be paid to the section Sound quality and effects (or “Sound effects”). This is where the main improvement tools lie. Depending on the model of your smartphone (Xiaomi 13, Redmi Note 12, etc.), the set of options may vary, but the basic functionality is everywhere.
⚠️ Attention: Activating some effects, such as Virtual surround sound, can significantly increase battery consumption.If you save energy, it is better to use these features only when charging is connected.
The same menu often features the Mi Sound Enhancer option, which automatically adjusts the frequency range depending on the type of headphones you have connected. If you use external acoustics or a Bluetooth headset, be sure to experiment with this switch, as it can dramatically change the perception of sound.
Use of Dolby Atmos and Graphic Equalizer
One of the most powerful tools in Xiaomi’s arsenal is Dolby Atmos, a three-dimensional sound system that distributes audio streams across virtual channels, which not only makes the sound volumetric, but often subjectively increases the volume by filling the frequency spectrum more densely.
To activate Dolby Atmos, go to Settings → Sound and Vibration → Sound Quality and Effects. Here you need to select a playback profile. Movies are best suited for Movies, and Music is best suited for music. In Intelligent mode, the system itself tries to guess content, but manual selection often produces a more predictable and louder result.
There's a graphical equalizer next to Dolby Atmos. It's a tool for fine-tuning frequencies. Standard presets like Rock or Pop can be useful, but the real volume gain comes from manual tuning. You can lift all the sliders of the equalizer up, but watch for distortion.
- 🎚️ Lift low frequency sliders (left) to add depth to bassam.
- 📈 The average frequencies are responsible for legibility of vocals and basic instruments – they can be twisted almost to the maximum.
- 🔊 High frequencies add to the ringing, but their excess makes the sound sharp and unpleasant.
Remember, the equalizer works in conjunction with the hardware. On the budget models of the Redmi series, excessively raising all frequencies can cause the speaker to become choked. The optimal setting is when the sound is loud but clean.
💡
Dolby Atmos and manual equalizer settings are the most effective regular methods of amplifying sound without installing third-party software.
Engineering menus and hidden codes to enhance
For advanced users who are not afraid to go into the system settings, there is access to the engineering menu, which is a hidden part of the system, designed for testing equipment by engineers in the factory, where you can directly control the amplification of the speaker signal.
To enter the engineering menu, open the Phone app and dial the code ##6484## or ##3646633##. If the code is suitable for your firmware version (Chinese or global), the CIT menu will open.
Inside the audio section, you're interested in the Volume tab. Here you'll see a list of profiles: Normal (normal mode), Headset (headphones), Handfree (loud communication). Select Normal and find Media or Music. You'll see a scale from 0 to 15 (or 0 to 255 in some versions).
The Way to Menu: CIT → Audio → Volume → Normal → MediaIncrease the value by a few steps. Don't put the maximum value right away, as it can lead to wheezing or even burnout of the speaker. After you change, press Set and check the result. If the sound is cleaner and louder, you're on the right track.
⚠️ Warning: Be extremely careful in the engineering menu. Changing unknown parameters can cause the phone to malfunction or the sound to disappear completely!
It is worth noting that new versions of HyperOS often block access to these parameters through codes. ADB-commands or third-party applications, which will be discussed below.
What do I do if the codes don't work?
Third-party applications to increase volume
If there is not enough regular funds, specialized applications from Google Play come to the rescue, they work as software amplifiers, passing an audio stream through their filter before sending it to the speaker, and the most popular and proven solution is the Volume Booster GOODEV app.
The way these programs work is simple: they add an additional gain cascade to the system mixer, but it's important to understand that this is software interpolation, and you're not creating new sound energy, you're squeezing the most out of the signal, which inevitably leads to more distortion.
- 🚀 Volume Booster GOODEV — classic genre, simple interface, the ability to boost up to 60% above the norm.
- 🎵 Bass Booster – Emphasis on low frequencies, which subjectively makes sound more powerful.
- 🔊 Super Volume Booster – offers desktop widgets for quick access.
When using these applications, it is critical to not set the boost value to the maximum, and typically the safe limit is considered to be 20-30% gain, exceeding this threshold turns your smartphone into a source of unpleasant cod and can knock the speaker out of order in minutes.
There are also applications like Poweramp Equalizer that require more complex setup but give a much better result, allowing you to fine-tune the compression and signal limiting to avoid clipping (overload).
Customizing the sound through ADB-team
For those who want to gain full control of the system without installing unnecessary applications, the method using ADB (Android Debug Bridge) is ideal, which allows you to change the system volume parameters that are not available through a regular interface.
To start, you need to enable USB debugging. Go to Settings → About Phone and 7 times click on MIUI or HyperOS to become a developer. Then, in advanced settings, activate Debugging over USB.
Connect your phone to your computer, install ADB drivers, and open the command line. To check the current media volume, type in the command:
adb shell settings get system volume_music_speakerTo change the volume, use the command to set the value, for example, to set the maximum level (usually 15):
adb shell settings put system volume_music_speaker 15The good thing about this method is that it doesn't load the processor with constant computation like booster apps. You just change the system constant. However, once the device is restarted, the settings can reset if they're not stored in the appropriate firmware profile.
☑️ Preparation for work with ADB
Comparison of volume-increasing methods
To make it easier for you to choose the right way, we have organized all the methods in a table, each of which has its advantages and disadvantages depending on your smartphone model and the purposes of use.
| Method | Difficulty | Efficiency | Risk for the speakers |
|---|---|---|---|
| MIUI/Equalizer settings | Low. | Medium | Minimum |
| Dolby Atmos | Low. | High (quality) | Low. |
| Engineering menu | Medium | Tall. | Medium. |
| Annexes (Boosters) | Low. | Very high. | High-pitched |
| ADB team | Tall. | Medium/High | Depends on the settings. |
As you can see from the table, regular funds are safer, but they give less gain. Software boosters give maximum volume, but they require caution. Engineering menus are the middle ground for power users.
And the physical condition of the device, if the speaker gets clogged with dust or moisture, no software methods can help, and regular cleaning of the speaker's mesh with a soft brush can return up to 20% of the lost volume.
💡
Use a Bluetooth speaker or headphones with your own amplifier if the sound is not enough, this will save the life of your smartphone speakers.
