Xiaomi smartphones are deservedly popular due to their excellent value for money, but even flagship models sometimes fail to produce enough volume to make the most of the device’s acoustic system.
There are many ways to increase volume, from standard system settings to the use of engineering menus and third-party applications. Some methods are completely safe, others require caution, as they can lead to distortion of sound or, in rare cases, damage to the speaker at extreme values.
In this article, we will look at all the current methods of increasing volume on Redmi and Poco smartphones. We will examine the regular means of the MIUI and HyperOS shell, hidden capabilities of the developer, as well as proven third-party solutions. Follow the instructions carefully so as not to harm your gadget.
Checking basic settings and cleaning speakers
Before you resort to complex methods, you need to rule out the trivial causes of quiet sound. Often the problem lies in contamination of the speaker grid or incorrectly configured profiles. Make sure that the sound settings do not activate the "No Sound" or "Do Not Disturb" mode, which can limit the volume of notifications and multimedia.
Special attention should be paid to physical cleaning. Over time, dust, pile and skin fat accumulate in the speaker's openings, which significantly reduces the output level. Carefully walk with a soft dry toothbrush along the speaker's grid. Do not use sharp objects or liquids, as this can damage the membrane.
⚠️ Attention: Using high-pressure compressed air to clean speakers can damage the inner membrane.It is better to use a soft brush or a special sticky tape.
Also check the equalizer settings. The standard Music app or the system audio settings often have presets. Try switching to Clear or Rock mode, which usually add high frequencies to make the sound subjectively louder. If you use a Bluetooth headset, check if the volume of the phone and headphones is synchronized, as they can be adjusted independently.
☑️ Diagnostics of sound
Use of the built-in Dolby Atmos equalizer
Many modern Xiaomi models are equipped with Dolby Atmos surround sound technology. It is not just a marketing ploy, but a powerful tool for correcting the sound profile. Unlike a simple equalizer, this system processes sound in real time, creating a surround sound effect and often raising the overall volume.
To activate the function, go to Settings → Sound and Vibration → Sound Effects. Here you will see the Dolby Atmos switch. Once activated, the system will prompt you to select a profile: "Auto", "Video", "Music" or "Voice". For maximum volume when watching movies, the video profile is best, and for music - "Music" with manual adjustment.
In manual equalizer settings, you can lift all the sliders up, but don't push them to the maximum, because it will cause wheezing and distortion (clipping), optimally raise the average and high frequencies, leaving the low (bass) at the average level, as they require more energy and can eat up the overall volume.
Dolby's Secret Settings
Settings for developers: absolute volume
The Android operating system that runs MIUI has a hidden menu for developers that contains options that can help unlock the full volume of Bluetooth devices and sometimes improve the performance of internal speakers. To enter this menu, you need to click on the build number several times in the About section.
Once you activate the developer menu, find Disable Absolute Volume. If this is activated, the system allows you to adjust the volume of your phone and connected device independently. Try changing the state of this switch: if it's on, turn it off, and vice versa. This often solves the problem of quiet sound in wireless headphones.
Also on the developer menu, you should pay attention to the limit of background processes. While this does not directly affect the volume, freeing up RAM can improve the performance of the audio codec, especially on budget models with a small amount of RAM. Make sure that the background does not work heavy application that intercepts the audio channel.
⚠️ Warning: Do not change other settings in the developer menu unless you are sure of their purpose. resizing the font or changing the animations can make the interface uncomfortable.
Engineering menu: fine audio tuning
One of the most effective ways to make Xiaomi louder is to use 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 audio channels. To log in, use the code ##6484# or #3646633## in the Phone app.
In the Engineering Menu (CIT) interface, you need to find the Audio or Audio Debugging section, and then you select the mode of operation, for example, "Normal Mode" (normal mode) or "Headset" (headphones), inside you will see a volume table (Level 0, Level 1, etc.) and the Digital Gain parameter. Increasing the Digital Gain value directly increases the volume.
Be very careful: the standard value is usually 120-140. Raising to 160-170 can give a noticeable increase, but values above 180-200 can lead to wheezing or burning of the speaker. Write down the initial values before changing so you can get everything back as it was.
💡
Before you change the parameters in the engineering menu, make sure to write down or take a picture of the original values, which is the only way to go back to the factory sound settings in case of problems.
| Parameter | Description | Recommended value | Risk |
|---|---|---|---|
| Digital Gain | Digital signal amplification | 150-160 | Medium (possible wheezing) |
| Analog Gain | Analog reinforcement | Change | High (risk of damage) |
| Max Vol Step | Maximum step of volume | 15 | Low. |
| Audio Type | Type of audio (media/call) | Media | Low. |
Third-party amplifiers
If built-in tools are not enough, Google Play Market apps come to the rescue. Volume Boosters work by software processing the audio stream, amplifying it before sending it to the speaker. Popular solutions include Volume Booster GOODEV, Bass Booster and analogues.
The way these applications work is simple: they create a virtual layer on top of the system's volume control, and once installed, you need to give the application the necessary permissions and use the slider to increase the gain, and most developers warn that it is not recommended to exceed the 20-30% mark, as this leads to severe distortion of the sound.
It is important to understand that these applications consume additional CPU and battery resources; on older smartphones, this can lead to slowing down the interface when playing audio; and some antiviruses may respond to the deep access to the system that amplifiers require.
System modification and Root rights
For advanced users willing to risk the guarantee for maximum results, there is a method of modifying system files. Obtaining SuperUser (Root) rights allows you to change audio configuration files, for example, mixer_paths.xml. This gives access to hidden gain options that are not available through the standard engineering menu.
The process requires customized recavator (TWRP) installation and root access through Magisk, and then superuser file managers (such as Root Explorer) can edit audio codec configuration files, and the changes only take effect after the device is fully rebooted.
⚠️ Attention: Editing system files mixer_paths.xml Without a backup, you can lose sound or "brick" your smartphone!
An alternative to manual editing is to install special modules for Magisk, such as Volume+ or Dolby Atmos Mod, which automatically make the necessary changes to the system, but installing such modules is only possible on an unlocked bootloader, which also voids the manufacturer's warranty.
💡
Getting Root rights and unlocking the bootloader officially voids the warranty on the device, and use these methods only if you are confident in your actions and are willing to be held accountable.
