The Xiaomi Redmi Note 5, released in 2018, is still a popular device due to its balance between performance and cost. However, over time, users often find that the standard volume of multimedia speakers is beginning to be lacking, especially in noisy rooms or outdoors. This can be due to both the software limitations of the MIUI shell and the natural wear of the hardware or contamination of the speaker mesh.
There are many ways to get around factory limits and return the device to its original sound power without the need to solder or replace components. In this article, we will discuss safe methods for setting system parameters, using engineering menus and third-party amplifiers. It is important to understand that excessive signal amplification can lead to distortion of the sound or damage to the speaker, so all actions should be done carefully and gradually.
Before we go to radical measures, it's worth checking the basic settings that are often ignored. Sometimes the problem isn't with the dynamics themselves, but with the wrong equalizer profile or the Bluetooth absolute volume feature enabled. Let's go through all the steps of optimizing your Redmi Note 5's audio subsystem.
Basic setup of sound and equalizer MIUI
The first step should always be to carefully check the standard operating system settings. The MIUI shell has built-in tools for fine-tuning the audio stream, which allow you to significantly improve the perception of sound without installing additional software. Go to the Settings β Sound and Vibration menu to access the main adjuster sliders.
Special attention should be paid to the built-in graphics equalizer. By default, it is often in the "Normal" or "Pop" position, which does not always give maximum volume. By switching to "Rock" mode or creating your own profile, you can artificially raise the decibel level at certain frequencies, which subjectively makes the sound louder.
- ποΈ Open the equalizer settings and select a preset with maximum amplification of high and medium frequencies.
- π Make sure that the option "Absolute volume" is disabled in the "Additional Sound Settings" section if you use Bluetooth headsets.
- π± Check if Do Not Disturb mode is activated, which may limit sound notifications.
Itβs also worth noting that some firmware versions have a separate setting to raise the volume in your pocket or when you call. If your Redmi Note 5 is running Android 9 or 10, these settings may be in the extended audio effects menu. Changing the equalizer profile is the safest way to affect the volume.
Using the Engineering Menu to Enhance the Speakers
For more advanced users who want to access hidden audio system settings, there is an engineering menu, a special diagnostic interface built into MediaTek or Qualcomm firmware (depending on the version of Redmi Note 5), which allows you to adjust (amplify) at the hardware level, accessed through the standard Phone application.
Enter ##3646633## or ##6484### to enter the test mode. You are interested in the section related to Hardware Testing or Audio. Here are the different use cases: talk speaker, multimedia speaker, headphones. By selecting the desired profile, you can manually raise the volume values for each of the 16 levels of adjustment.
β οΈ Warning: Changing the values in the engineering menu without understanding the consequences can lead to the speaker wheezing or their complete failure.
The most interesting tab is Audio β Audio Debug. Here you can find the Digital Gain parameter, which directly affects the digital amplification of the signal before it is fed to the amplifier. The standard value is often limited by software, and a small increase in the standard value can give a noticeable increase in volume. However, remember that the physical limit of the speaker membrane has not been canceled.

Third-party sound amplifiers
If the built-in tools aren't enough, Google Play apps designed specifically to overcome the limitations of Android come to the rescue. Software like the Volume Booster GOODEV or Super Volume Booster create a software layer on top of the system mixer, forcefully amplifying the output signal, and they work on a software amplification principle similar to how a volume slider works, but with a margin of 100%.
The use of such utilities requires caution. When setting the gain above 20-30% above normal, the sound can begin to "crack" due to digital distortion (clipping), this is especially noticeable at low frequencies. For the Xiaomi Redmi Note 5, the optimal boost is in the area of 10-15%, which gives a noticeable effect without critical deterioration in quality.
- π² Install a high-rated app and check compatibility with your version of Android.
- ποΈ Start the gain with minimum values, gradually adding percentages until distortions appear.
- π Use the Reset feature inside the app if the sound has become indistinct.
Some apps require special permissions through ADB or Root rights for maximum efficiency. Without root access, they work within the security constraints of Android, but even that is often enough to comfortably watch videos in a noisy place.

Activation of Dolby Atmos and Sound Mods
One of the most effective ways to improve not only the volume but also the overall sound quality on the Redmi Note 5 is to install Dolby Atmos modules. Officially, this feature may not be available in global firmware versions, but enthusiasts have ported the module to work on most Xiaomi devices.
To install, you'll need to unlock the bootloader and get the Root rights (usually through Magisk), and then you'll load the archive with the Dolby Atmos port into the module repository, and the system starts processing the stream through powerful spatial sound algorithms, which subjectively makes the device much louder and more saturated, which is especially useful for movies and games.
An alternative is to install the Viper4Android modules, which provide even more flexible settings for the equalizer and compressor, and the compressor plays a key role in this case: it raises quiet sounds, preventing loud ones from going into clipping, which creates a constant high volume effect without overloading the speakers.
| Method | Difficulty | Efficiency | Risk |
|---|---|---|---|
| MIUI equaliser | Low. | Medium | No. |
| Engineering menu | Medium | Tall. | Medium. |
| Booster applications | Low. | Medium | Low. |
| Dolby Atmos (Root) | Tall. | Very high. | High-pitched |
Physical cleaning and maintenance dynamics
Often the reason for the quiet sound on the Xiaomi Redmi Note 5 is trivial β pollution. The bottom multimedia speaker is located in the area of active collection of dust, pile and small debris. Over time, the speaker grid gets clogged, which physically prevents the sound wave from coming out. Visually, this may be invisible, but acoustic resistance increases many times over.
To clean, use a soft toothbrush or a special brush for electronics. Carefully, without heavy pressure, walk along the speaker grid, sweeping out the dust. You can use isopropyl alcohol by applying a couple of drops on the brush (not on the phone!) to dissolve fatty contamination. Regular cleaning can return up to 30% of the lost volume.
β οΈ Attention: It is strictly forbidden to use sharp objects (needles, pins) to pick the speaker grid. You can pierce the membrane, and then the speaker will have to change completely.
Also check the safety glass or case. Sometimes they can overlap the speaker hole, especially if the case is not original or has deformed over time. Remove the case and check the volume - perhaps the problem is solved instantly. Physical obstacles are a common but easily removable cause of quiet sound.

Use paint tape: stick a sticky part to the speaker grid and pull back abruptly, which will help pull dust from the bottom of the mesh cells without getting inside the device.
Problems with audio codec and flashing
In rare cases, a quiet sound may be due to a software error in the audio codec drivers, which is common after failed MIUI updates or when using custom firmware where the drivers are not correctly selected. If the volume has gone down abruptly after the update, it makes sense to consider resetting or flashing the device.
System file integrity can be verified through Recovery mode. If the problem is a software failure, a full reset (Wipe Data) often helps to return factory gain settings. However, before doing this, make sure to back up the data, since all files will be deleted. Resetting eliminates software conflicts affecting sound.
If nothing works, it may be a hardware problem: the speaker plume has gone, the contacts on the board have oxidized, or the audio amplifier itself has failed, and in such cases, the software methods are powerless, and intervention in the service center is required to diagnose and replace components.
