How to increase the sound of Xiaomi Redmi 8A: the complete guide

Redmi series smartphones, including the 8A, are deservedly popular due to their excellent price-performance ratio. However, the budget speaker system is often the subject of complaints from users, especially those who are used to flagship solutions. The loudness of the speakers on the Xiaomi Redmi 8A can seem insufficient in noisy places, on the street or while watching video in the company. Standard system settings do not always allow you to squeeze the maximum from existing hardware.

Fortunately, the Android operating system, and in particular the MIUI shell, provides many hidden features and engineering menus. There are several proven methods that will allow you to significantly increase the volume level without buying additional hardware. In this article, we will discuss software and hardware solutions to the problem of quiet sound.

It's important to understand that raising the volume above factory limits can cause sound distortion or even damage to the speaker if not taken care. We'll look at safe methods to help you improve your device's acoustic performance. Let's start with basic settings that are often overlooked.

Basic sound settings and equipment inspection

Before you go to complex manipulations, you need to make sure that the problem is not in the trivial settings or physical obstacles, often users forget to check the individual volume channels or do not notice the contamination of the speaker grid. The first thing to do is to conduct a thorough diagnosis of the current state of your Redmi audio system. 8A.

Check to see if Do Not Disturb or Silent Mode is activated, which can limit system sounds, and make sure that the volume slider is twisted to the maximum for media, not just for calls. Modern versions of MIUI have volume control divided into several categories, and this is often confusing.

Visual inspection of the mesh of conversational and multimedia speakers is also a must. Even a microscopic layer of dust or pile from your pocket can reduce the volume by 20-30%. Carefully clean the holes with a soft toothbrush, without using liquids and sharp objects that can damage the membrane.

⚠️ Warning: Never use needles or pins to clean speakers.You can pierce the safety net and damage the speaker itself, resulting in complete loss of sound or wheezing.

After physical cleaning, try playing the test track. If the sound is cleaner but still quiet, go to software tuning methods. Sometimes the problem is solved by simply restarting the system's audio services, which you can do through a device reboot.

Use of built-in equalizer and Dolby Atmos

The MIUI shell on the Redmi 8A is equipped with built-in audio tools, which many users ignore by relying on a standard profile that is often too flat. Competent equalizer settings not only improve the timbre, but also visually raise perceived loudness.

To access the audio settings, go to Settings → Sound and Vibration → Sound Effects. Here you will find an equalizer with preset profiles. Rock, Pop or Jazz profiles usually have higher peaks at medium and high frequencies, making the sound subjectively louder and brighter.

You should pay special attention to Dolby Atmos technology if it is available in your firmware version. This surround sound algorithm can significantly enrich the sound. In the Dolby Atmos settings, select the Auto or Video profile to maximize the power output when viewing content.

If you don't like standard presets, try creating your own equalizer profile. Lift sliders in the mid-range (about 1 kHz - 4 kHz), because the human ear is most sensitive to this range, which will create the illusion of higher volume without critically increasing the signal amplitude, which protects the speaker.

Engineering menu and deep audio tuning

The most powerful tool for increasing volume is the Android Engineering Menu, which allows you to change the system volume limits at the driver level. For the Xiaomi Redmi 8A, this method is the most effective, but requires caution.

Try typing the code ##3646633## in your phone book. If the code doesn't work (which is often the case on global versions of MIUI), you'll need to install the Mtk Engineering Mode app or the Play Market analogue. After you log in, go to the Hardware Testing → Audio → Audio Debug Utility tab.

Here you'll see a list of scenarios (Scenario) like "Normal Mode" (normal mode), "Headset" (headphones) and "Handsfree" (loud communication). Select "Normal Mode" and "Media" type. You'll see a volume scale (Level 0-15). By increasing the value in the "Max Vol" field, you raise the limit for the corresponding volume level.

⚠️ Warning: Changing the settings in the engineering menu may cause permanent damage to the speaker or software failure of the system. Write down the initial values before making any changes so you can roll back.

It is recommended to increase the values gradually, for example, by 5-10 units, and immediately check the result. Do not aim to set maximum values in all ranges, as this will lead to severe distortion (clipping).

Third-party applications for sound amplification

If you think it's too risky to mess with the engineering menu, Google Play's specialty apps will come to the rescue, and they work like software amplifiers, boosting the digital signal before sending it to the DAC. For Redmi 8A, these apps can be a great solution.

One of the most popular solutions is the Volume Booster GOODEV app, which is easy to use: once installed, you just move the gain slider, but it's worth remembering that these applications load the processor and can drain the battery faster, and they can also introduce digital distortions at maximum amplification.

Another powerful tool is Precise Volume or Equalizer FX. These apps not only amplify the sound, but also fine-tune the frequency balance. Some of them have a feature called "Bass Boost" that adds depth to the sound, making it richer and more voluminous, which is especially true for compact smartphones.

When using third-party amplifiers, it is important to monitor the sound quality. If you hear crackling or sand at high frequencies, immediately reduce the gain level.

System Cleaning and MIUI Optimization

Sometimes the quiet sound on the Xiaomi Redmi 8A is the result of software conflicts or accumulated debris in the system. MIUI shell is known for its aggressive work with background processes, which can sometimes affect the performance of audio drivers. Regular optimization helps to maintain stable multimedia.

Use the built-in Security app to clean up the cache and close unnecessary background processes. It’s also worth checking system updates in Settings → About Phone → Update MIUI. Xiaomi engineers regularly release patches that correct errors in the audio codecs.

If the problem occurs after you install a particular application, try removing it. Some programs may intercept audio stream control or interfere with system audio settings.

Resetting the audio settings to the factory can also help: Go to the sound settings and find the reset option (if available in your version of MIUI) or simply reset all the phone settings through the recovery menu, pre-saving the data. This will return all system volume limits to the original state.

Hardware restrictions and modifications

Remember, the Redmi 8A is a budget device, and its acoustic system has physical limitations: the size of the case, the volume of the resonance camera and the quality of the speaker itself determine the maximum volume ceiling. Software amplification cannot work wonders indefinitely.

There's a physical modification method, which is to improve the acoustic design, and some enthusiasts carefully remove the back cover and remove some of the soundproofing materials that cover the speaker channel, or add a small socket, but it's a complex process that requires electronics repair skills.

A safer hardware method is to use external amplifiers or portable speakers that are connected via Bluetooth or AUX (if you have an adapter), which radically solves the problem of volume without the risk of damaging the smartphone, and for listening to music in the company, this will be the best solution.

⚠️ Attention: Opening the case of the smartphone Redmi 8A It requires heating the back cover and using suction cups, and without experience, you risk breaking the glass or damaging the plumes, leading to costly repairs.

If you notice that the sound became quiet suddenly, without any changes in the settings, and cleaning the speaker does not help, the speaker module itself may have failed, in which case the software methods are useless, and you will need to replace the spare part in the service center.

Use headphones with your own amplifier or active Bluetooth headphones for high-quality and loud sound without loading on the smartphone speaker.
