How to enhance the sound speaker on the Xiaomi phone: the complete guide

Many owners of Xiaomi, Redmi and POCO smartphones sooner or later face a situation where the standard volume of the multimedia speaker is no longer enough in noisy places. Whether it is loud communication, watching video in transport or listening to music on the go, standard values are often not enough for comfortable use. This is especially true for low-end models, where manufacturers save on audio components, but even flagship devices may require additional adjustment.

Fortunately, the MIUI shell and its current version of HyperOS provide users with a wide range of tools to fine-tune the audio stream.You don’t have to be an acoustic engineer or have root rights to squeeze the most out of the device. In this article, we’ll break down software techniques, hidden engineering menus, and hardware nuances that will help you amplify the sound of the speakers on your Xiaomi smartphone.

Before we move on to radical measures like installing third-party amplifiers, make sure the basic system settings are maximally twisted and work correctly. Often the problem lies not in weak dynamics, but in the wrong software or restrictive security features that Xiaomi implements by default to protect users’ hearing.

Start with the most obvious but often ignored step, which is checking physical limitations and basic sliders. Current versions of Android and its shells have volume limits that can be bypassed or recalibrated. Press the volume buttons on the side of the case, then tap the three dots or gear in the menu that appears.

Make sure the Multimedia slider is in the extreme right position. Sometimes the system may reset after an update or reboot. Also check if no sound or no disturb mode is activated, which can limit audible notifications and system sounds, creating the illusion of a quiet speaker.

One of the most powerful built-in features for improving sound quality and volume is the Dolby Atmos equalizer, which is pre-installed on most modern Xiaomi models. This technology allows you not only to amplify the signal, but also to redistribute frequencies, making the sound more voluminous and saturated, which is subjectively perceived as increasing volume.

To activate and configure this feature, go to Settings → Sound and Vibration → Sound Effects. Here you will see a Dolby Atmos switch. Turn it on and select the appropriate profile. Auto or Video is often the best way to maximize amplification, as they dynamically adjust frequencies to the content.

However, standard presets can be too soft. To manually adjust, click on the Settings or Equator button inside the Dolby menu. Here you can lift all the frequency sliders upwards by creating your own Maximum Volume profile. Be careful: too much low-frequency lift can cause the speaker to wheez (rattle) because its amplitude is limited.

💡

Try lowering the lowest-frequency sliders (left) a little and raising the middle and high-frequency sliders, which will make the speech and the main instruments louder without risking damaging the speaker with bass.

It's important to understand that Dolby Atmos doesn't work in all apps the same way. Some video players or streaming services may ignore the system settings of the sound using their own playback algorithms. In such cases, the equalizer settings may not apply, and you'll have to look for volume settings inside the app itself.

If standard MIUI is not enough, specialized amplifiers from the Google Play Store come to the rescue, and they act as intermediaries, passing audio through their amplification filter before sending it to speakers, and one of the most popular and effective solutions is the Volume Booster GOODEV app, or the Super Volume Booster.

The way these applications work is simple: they programmatically increase the amplitude of the sound wave. But there's a major risk. Exceeding a certain gain threshold can overload and physically rupture the speaker membrane. Most applications have warnings about this, but users often ignore them in pursuit of volume.

Using third-party boosters requires compliance with the measure. It is not recommended to raise the gain level (Boost) above 20-30%. values of 60% or 100% are almost guaranteed to lead to severe distortion and, ultimately, to break the audio component.

There are also more sophisticated tools like Viper4Android, but installing them requires obtaining superuser (Root) rights and unlocking the bootloader, which is unwarranted and can be dangerous for inexperienced users.We won't detail this method as part of the basic instruction, but keep in mind that this is the most powerful way to change the sound at the system level.

For those who are willing to take risks and have technical skills, there is access to the hidden CIT engineering menu (Customer Integration Test), a diagnostic tool built into Xiaomi’s firmware that allows you to test all components of the device, including speakers, and in some versions of the software to change the parameters of the audio output.

To get into the testing menu, open the Phone app and dial the code ##6484## or ##4636##. If the code doesn't work, go to Settings → About → The MIUI version and quickly tap 7-10 times on the logo to activate the developer menu, then find the CIT item in the main settings.

From the CIT menu, select the speaker test (usually called Speaker or Audio) where you can hear the maximum volume test sound. Sometimes, repeating the tests or switching modes on this menu can wake up speakers if they were not working properly due to a failure. However, direct change (gain factor) in new versions of Android is often blocked to avoid legal problems with volume standards.

Often the problem with quiet sound is not the settings, but the banal pollution of the dynamic grid, where, in six months of use, the pockets get stuffed with dust, pile from clothes and grease that clog the holes, which can reduce the volume by 30-50%, creating the feeling that the speaker has sat down.

To clean, use a soft toothbrush with dry bristles. Carefully, without heavy pressure, walk in circular motions along the speaker grid. You can also use a sticky tape (scotch), gluing and peeling it off the surface to pull dust from the depths. It is strictly forbidden to use sharp objects (needles, toothpicks), as they are easy to pierce the protective membrane.

There's a popular but controversial method of blowing out sound. You can find special low-frequency humming tracks on YouTube that make the speaker's membrane virulate at high amplitude, theoretically knocking the dust out. Turn on this track at maximum volume for 1-2 minutes. This method can help if the pollution isn't critical.

💡

Regularly cleaning the speakers with a dry brush once a month prevents volume reduction and prolongs the life of audio components.

The table below gives the main causes of quiet sound and methods to address them so you can quickly diagnose the problem:

And software conflicts, too. Sometimes, after you upgrade MIUI or install a new app, the audio settings can get lost, and in such cases, resetting all your phone settings (not to be confused with a full data reset, although it is sometimes necessary) helps. Be sure to back up your important data before resetting.

Also check if the phone is Bluetooth connected to another device. Sometimes the smartphone automatically connects to the headphones or speaker lying nearby, and the sound goes there, not to the speaker of the phone. Turn off Bluetooth completely for verification.

⚠️ Attention: Using maximum gain values in third-party applications (Volume Booster) on a continuous basis leads to overheating of the speaker coil and its inevitable failure!

If none of the above has worked, and the sound remains quiet even on test tracks in the engineering menu, the problem is probably hardware in nature. The speaker may have moved away from the contacts (the plume) due to a fall, or its resource is simply exhausted. In Xiaomi models, replacing the lower speaker or the main multimedia module is a procedure that is inexpensive and fast.

In conclusion, for most users, the best solution is to combine the right setup of the built-in Dolby Atmos and regular physical cleaning of the speakers. These two measures are enough to achieve excellent sound without the risk of damaging the device.
