Xiaomi’s modern smartphones are known for their excellent value for money, but the multimedia capabilities, namely the volume of the built-in speaker, are often criticized. Users face a situation where the maximum sound level is not enough to comfortably watch videos in a noisy place or listen to music on the street, this is especially noticeable on the budget models of the Redmi and Poco series, where manufacturers save on the acoustic system to reduce the cost of the device.
Fortunately, the MIUI and HyperOS operating system that power these gadgets has the most customization capabilities. There are many software ways to get the most out of speakers without having to physically disassemble or solder. In this article, we will detail how to boost the sound on Xiaomi using standard tools, hidden engineering codes and third-party software.
Before you start radical methods, make sure that low volume is not caused by software failure or banal locking of the output hole. Often the cause of quiet sound is dust, villi from your pocket or protective film, covering the grid speaker. Initial diagnosis will help to avoid unnecessary manipulation of the system settings.
Basic test and cleaning of speakers
The first step before any software setup is to physically inspect the device. Even a microscopic layer of dust can cover up to 30 percent of the sound stream, making the sound deaf and quiet. Use a soft toothbrush or a special sticky tape to clean the grid of the lower and conversational speakers. Be careful not to use sharp objects so as not to damage the membrane.
It's also worth checking if In-pocket or Quiet Mode is accidentally activated in the notification curtain. Sometimes system failures can reset the media volume slider to a minimum after rebooting or updating. Make sure that all sliders are twisted to maximum in the audio settings.
⚠️ Warning: Do not use high-pressure compressed air to clean speakers.The flow of air can damage the speaker's thin membrane, leading to wheezing or full acoustics failure.
If the physical cleaning didn't work, we're going to go to software settings, and the MIUI shell has a lot of hidden potentials that can be activated through the Developer Menu or special engineering codes.
💡
Use the Task Manager app or the built-in Cleanup function to check the system status before changing your audio settings to eliminate background processes that affect performance.
Set up the equalizer and Dolby Atmos
One of the most effective regular tools is the built-in equalizer, which allows you not only to increase the overall volume, but also to adjust the frequencies so that the sound seems louder and cleaner. To access it, go to Settings → Sound and vibration → Sound settings. Here you will find preset profiles such as Rock, Pop or Jazz, which already have elevated levels of medium and high frequencies.
To fine tune it, you should use the manual equalizer mode. Raise the sliders in the high and medium (Mid) regions, leaving the bass (Low) at the standard level. This will create the effect of presence and increase perceived loudness without distortion. Owners of flagship models can also find the Dolby Atmos setting, which must be activated and switched to Auto or Movie mode.
- 🎚️ Lift high frequency sliders for greater sound clarity.
- 🔊 Activate Loud Mode in Media Settings if it is available for your model.
- 🎧 Use the “In Headphones” profile even for speakers if the system allows for global application of settings.
Remember that over-amplifying certain frequencies can lead to wheezing, especially at maximum volume. Experiment with settings gradually, listening to tracks of different genres.

Engineering menus and hidden codes
For advanced users who want to know how to boost the sound on Xiaomi at the deep system level, there is an engineering menu available, a hidden section of the system designed to test equipment by engineers in the factory, and is logged in through a set of special codes in the Phone app.
The most common code to access audio testing is ##6484## or ##3646633#. Once you enter the combination, the CIT (Customer Integration Test) menu will open. You will need to find the audio-related section (often called Audio or Speaker) where you can check each speaker separately and, in some firmware versions, change the amplification settings.
Popular codes for entering the test menu:
#6484## - The main test menu
#3646633## - Menu of Engineering (MediaTek)
#4636## - Phone Information MenuIt is important to understand that the functionality of the engineering menu is highly dependent on the processor (Snapdragon or MediaTek) and the shell version. On new versions of HyperOS, access to the change (Gain) can be blocked to avoid damage to the hardware.
⚠️ Warning: Be extremely careful in the engineering menu. Changing unknown parameters can lead to unstable phone operation or loss of warranty%.
What do I do if the codes don't work?
Third-party amplifiers
If there is not enough regular funds, specialized applications from the Google Play store come to the rescue, they work on the principle of software compression and normalization of audio, allowing you to exceed the standard volume limit set by the manufacturer.
One of the most popular and effective solutions is the Volume Booster GOODEV app. It's easy to use: after installation, you just move the Boost slider to the right. However, it is not recommended to set a value higher than 20-30%, as this can lead to overloading of the speaker. Another powerful tool is Equalizer FX, which combines an equalizer and an amplifier.
When using these programs, it is important to monitor the temperature of the device. The amplification of sound requires more energy from the audio chip, which can lead to heating of the bottom of the smartphone. If you notice overheating or distortion (wheezing), immediately reduce the gain.
Comparison of sound amplification methods
To make it easier for you to choose the right way, we have compiled a comparative table of the main methods of volume raising on Xiaomi devices.
| Method | Efficiency | Risk to the device | Difficulty |
|---|---|---|---|
| Cleaning the speakers | Low/Mediocre | Absent. | Low. |
| MIUI equaliser | Medium | Absent. | Low. |
| Engineering menu | Tall. | High-pitched | Tall. |
| Booster applications | Tall. | Medium (wear and tear) | Low. |
As you can see from the table, software methods are the best, but they carry certain risks. The best solution is to combine regular cleaning of the speakers with a proper adjustment of the built-in equalizer, which allows you to increase volume without critically affecting the hardware.
The use of amplifiers should be considered as a temporary measure for specific situations, for example, to watch a quiet video on a noisy train, rather than as a permanent mode of operation.
💡
It is safest to use built-in MIUI tools and regular cleaning, and to resort to third-party boosters only when urgently needed.
Problems after the update and resetting settings
Often users notice a drop in volume after updating MIUI or HyperOS. This may be due to a change in audio drivers or resetting user profiles. In such cases, the first thing you should do is reset the audio settings to factory values in the equalizer menu.
If the problem persists, a deeper reset may be required. Go to Settings → Advanced Settings → Recover and Reset. Here you can select the option to reset all settings (not data!), which will return system parameters, including audio, to the original state.
In rare cases, a quiet sound may indicate a hardware problem that occurred independently of software updates. If the speaker started wheezing or disappeared altogether, software methods will not help.
