How to Make Xiaomi Sound Louder: Expert Guide

Modern Xiaomi and Redmi smartphones are famous for their performance, but the built-in speakers do not always boast enough power for noisy places or fans of loud music. Often users are faced with a situation where even on the maximum scale of adjustment the sound seems not saturated or quiet enough, this is especially true when watching movies or listening to audio books in the conditions of street noise.

Fortunately, Android, in conjunction with the MIUI or HyperOS shell, provides a wide range of tools to fine-tune the audio output. You can significantly improve your audio perception without resorting to complex technical manipulations. In this article, we will discuss all the available methods, from simple settings in the menu to the use of advanced engineering codes.

Understanding how your device's audio track works will not only increase the volume, but also help maintain the quality of playback. It's important to act consistently so that you don't damage the dynamic head with software overflow. Let's start with the basic but often ignored system settings.

⚠️ Warning: Excessive sound amplification by software methods can lead to wheezing, distortion and, in rare cases, to overload and failure of smartphone speakers.

Basic setup of the audio system in MIUI

The first step should always be to check the standard settings, as many users are simply unaware of the existence of hidden equalizer functions. The MIUI shell implements a fairly advanced audio processing module that by default can be disabled or configured incorrectly. To access it, you need to go to the Settings menu → Sound and vibration → Sound effects.

Here you will find the Mi Sound Enhancer switch, which is specially designed by Xiaomi engineers to improve the sound quality in headphones. However, its functionality is also useful for external speakers if you choose the right profile. The system offers ready-made presets for different genres of music, but the most interesting is the manual tuning mode.

• 🎚️ Select Manual mode for detailed frequency adjustment.
• 🎧 Make sure that the “Optimize for” option is “Hearphones” or “Dynamic”, depending on what you are using.
• 🔊 Lift the high and medium frequency sliders to add "air" and clarity to the sound.

You don't want to twist all the sliders to the maximum, because that would lead to digital distortions known as clipping, but you'd better do a little lift in the 2-4 kHz region, where most of the human voice and most instruments are, and that would create a subjective sense of greater volume without really increasing the amplitude of the signal.

Use of the Engineering Menu for Calibration

For a deeper setup, there is a hidden section known as the Engineering Menu, which is designed for service engineers, but is also available to ordinary users through a dedicated service menu. USSD-Enter the combination ##6484## in the Phone application will open a testing menu where you can check and configure the work of hardware components.

The list that opens will include a sound test item (often called Speaker or Audio) that can run an automatic speaker test to help detect hardware problems, and if the speaker wheezes or is quieter than normal, even on a test, software techniques may not help — it may require cleaning or replacing the component.

In some firmware versions, you can reset the audio codec to factory values through this menu, which is useful if the sound is not working properly after the system update. Just reset and restart the device so that the system can reinitiate the audio drivers.

Be careful when changing unknown parameters in the engineering menu. Accidental activation of test modes can block certain functions of the phone before rebooting. The main goal here is diagnostics, not direct volume control, although resetting settings often solves the problem of quiet sound.

Application of third-party equalizers and amplifiers

If the built-in tools are not enough, apps from the Google Play Store come to the rescue. There are many quality equalizers that intercept and amplify the audio stream before sending it to speakers. One of the most popular and secure solutions is the Volume Booster GOODEV app or various implementations of Precise Volume.

The principle of such programs is to programmatically increase the audio signal (gain), which allows you to raise the volume above the standard limit of 100%, sometimes up to 200% or even 600%, but using such applications requires a reasonable approach, as they can cause serious distortion.

It is recommended to set the gain to no more than 20-30% above normal, exceeding this threshold often makes the sound illegible and "porridgeous". In addition, constant work at the limiting power reduces the life of the dynamic membrane.

⚠️ Warning: When using volume boosters, monitor the temperature of the smartphone body. The enhanced operation of the audio chip can cause additional heating of the device.

Setup of multimedia players

Often, the problem with quiet sound is not the system, but the settings of the specific application you use to play content, for example, video players like VLC or MX Player have their own amplification settings, independent of the system, which allows you to raise the volume specifically for a movie or series.

In the VLC for Android player, you can increase the volume to 200% by simply swiping up the screen during playback, and in the audio settings, you should check whether night mode or volume normalization is activated, which can artificially lower signal peaks.

For streaming services like YouTube or Netflix, settings can be hidden in your account or playback qualities. Sometimes, a drop in video quality from 4K to 1080p changes the audio codec to a louder one, although this is not a guaranteed method. In Chrome, you can use extensions to amplify sound if you watch content through the web version.

Remember that different audio file formats have different original volumes. FLAC or WAV files can sound quieter than compressed MP3s with high bitrate due to differences in mastering. Using normalization in music players helps to level this scatter.

Physical causes and cleaning of speakers

Before you get into complex settings, you should rule out the trivial physical reasons. In six months of use, the speaker accumulates a huge amount of dust, pile and skin fat in the grid, which acts as a silencer, significantly reducing the sound output, especially at high frequencies.

You can use a soft toothbrush or a special sticky tape to clean the speaker hole, brush carefully, sweep the dust out, and do not use sharp objects such as needles or pins, as you can damage the safety net or the membrane itself.

• 🧹 Use a soft brush to remove surface dust.
• 💨 Blow the holes with compressed air (balloon), but not too close.
• 🧽 Gently wipe the mesh with a dry microfiber cloth.

Another physical cause may be a case. Some protective cases have too narrow cutouts or completely block out the sound, especially if the phone is on the table with the screen down.

💡

Use a Sound Cleaner app or similar that generates low-frequency vibrations to push water and dust out of the speakers, which is useful if the phone is caught in the rain.

Hidden capabilities of Bluetooth adapter

If you use wireless headphones or speakers with Xiaomi, the problem may be Bluetooth codecs. In the (Developer menu) you can find settings that affect the quality and volume of audio transmission. To enter there, you need to click 7 times on the build number in the "About Phone" section.

In the developer menu, find the item "Switch off absolute volume." If this feature is on, the volume of the phone and headphones is adjusted separately, which sometimes allows you to bypass the software limitations of Android. Try to change the state of this switch and check the result.

Also worth paying attention to is the audio codec you choose. Codecs like LDAC or aptX HD provide high quality, but may have lower power output than the base SBC codec. Switching to SBC in some cases makes the sound subjectively louder, albeit less detailed.

⚠️ Attention: Changes to the developer menu can affect the stability of the Bluetooth connection.If the headphones stop connecting, reset the Bluetooth settings in the same menu.
