How to increase the sound of the speaker in the Xiaomi phone: a complete guide

Many users of Xiaomi, Redmi and POCO smartphones face the problem of quiet media sound. Often built-in software limitations or software glitches do not allow you to unlock the potential of the audio system to its full capacity. Owners of budget models are especially often looking for ways to increase the sound of the speaker in the Xiaomi phone to comfortably watch videos or talk on speakerphone.

Fortunately, the MIUI and HyperOS shells provide a number of hidden tools, as well as standard settings that significantly improve audio output. In this article, we will discuss safe audio amplification methods, working with engineering menus and software solutions that do not require superuser rights (Root).

Before we get to the tricky part, we need to make sure that it's not the trivial stuff that's the problem, and sometimes the quiet sound is the result of a dynamic grid contamination or a conflict of running applications, and we're going to look at all the stages of diagnosis and configuration from the simple to the more advanced.

Basic diagnostics and physical cleaning

The first step should always be to check the physical condition of the device. The speaker in a smartphone is a miniature device that gets clogged with dust, pocket pile and skin fat. Even a microscopic layer of dirt can reduce the volume by 30-40%, creating the illusion of a software malfunction.

Use a soft dry toothbrush or a special sticky electronics tape to clean your body. Walk carefully through the speaker grid, trying not to push dirt inside the case. It is strictly forbidden to use sharp objects such as needles or pins, as you risk damaging the speaker membrane, leading to wheezing or complete absence of sound.

It's also worth checking if the protective film is glued to the area of the talk or multimium speaker. Some users accidentally tape the output holes when changing glass or installing poor-quality protective glasses. Make sure that the smartphone case does not block the sound channels.

⚠️ Warning: Never use high-pressure compressed air or vacuum cleaner to clean the speaker.The flow of air can damage the thin membrane or tear off the speaker's adhesive mount inside the housing.

After physical cleaning, restart the device. This is a standard procedure that resets the temporary errors of audio drivers. If the sound got louder, the problem was only pollution. If there is no change, then we go to software settings.

Setup of built-in equalizer and sound effects

MIUI and HyperOS have built-in audio tuning tools that many forget. The standard equalizer allows not only frequency changes, but also presets that users often ignore.

To access the settings, go to Settings → Sound and Vibration → Sound Effects. Here you will find the Mi Sound Enhancer switch. Enabling this feature automatically optimizes the sound depending on the type of headphones used (if connected) or improves the stereo effect for built-in dynas.

So, you should pay special attention to the hand equalizer, and by lifting the high and medium sliders, you can make the sound sound sound more loud and legible, which is subjectively perceived as increasing volume. Bass frequencies, on the contrary, often eat up the volume of the amplifier, so you can turn them down a little bit.

💡

Turn on Automatic Improve in the sound settings – it tries to dynamically adjust the volume depending on the surrounding noise, although it does not always work correctly.

Don’t forget to check the Dolby Atmos settings if your smartphone model supports this technology. Modes like Film or Dynamic often give you more powerful and surround sound than the standard Music mode.

• 🎚️ Lift sliders on frequencies 2k, 4k and 16k speech-learning.
• 🔊 Enable the "Mi Sound Enhancer" option for global audio streaming improvements.
• 🎧 Select the "Hearphones" profile even for the speaker, if there is such an option in your version MIUI, It sometimes changes the algorithms of amplification.

Using an engineering menu to amplify sound

One of the most effective ways to increase the sound on Xiaomi is to use the engineering menu, which is a hidden part of the system, designed to test equipment by engineers in the factory, where you can directly control the level of gain of the audio track.

To enter the engineering menu, open the Phone app and enter the code ##6484##. If the code didn't work, try ##3646633##. From the menu that opens, select the Hardware Testing tab, then go to Audio → Audio Debugging.

In this section, you'll see a list of modes: Normal Mode (normal mode), Headset Mode (headphones), Loudspeaker Mode (loudspeaker) and Headset+Loudspeaker Mode. We're interested in Loudspeaker Mode. Choose it, and in the next menu - TMOS or Playback.

In the list of parameters that opens, find the Volume-related rows. These are usually parameters. AVG_GAIN or digital values, increase their value Step-by-step (for example, by 5-10 You can't set the maximum values right away. After each change, press the Set button and check the sound.

⚠️ Warning: Do not set maximum gain (Max) values right away. This can lead to wheezing, distortion and, in the worst case, burnout of the speaker due to exceeding the permissible power.

It is important to understand that the interface of the engineering menu may differ on different versions of Android and MIUI. On some new models, access to the change (gain) may be blocked or require a password, in which case this method may not be available without deep flashing.

Third-party sound amplifiers

If the built-in tools aren't enough, Google Play Market apps come to the rescue, and they act as software amplifiers, processing the audio stream before it's sent to the speaker, and the most popular and efficient solution is the Volume Booster GOODEV app.

The way these applications work is simple: they add an extra layer of gain over the system limit of 100%. However, using third-party software requires caution. Digital over-amplification leads to digital distortion (clipping) when the sound wave is "cut off", creating an unpleasant crack.

Another powerful tool is the Precise Volume or Equalizer FX app. They let you create your own volume profiles in 1% increments, which gives you more subtle control than the standard 15 steps of Android. You can also use the VLC Player to watch videos, since this player has its own built-in amplifier up to 200%.

When using boosters, monitor the temperature of your smartphone. Real-time audio processing software loads the processor, which can lead to heat and fast battery discharge.

• 📱 Volume Booster GOODEV — Simple interface, quick amplification up to 60%.
• 🎚️ Precise Volume – Accurate volume setting with 1 increments%.
• 🎵 Equalizer FX — Combining an equalizer and a bass boost for deep tuning.

Comparison of sound amplification methods

To make it easier for you to choose the right method, we have prepared a comparison table that will help you assess the risks and effectiveness of each method for your specific situation.

As you can see from the table, the safest method is to set the equalizer and physically clean it. The engineering menu is great, but it requires care. The booster apps give maximum volume but sacrifice sound quality.

💡

A combined approach (cleaning + equalizer + light booster) often yields a better result than trying to squeeze the maximum with one method.

The Impact of Bluetooth Codecs and External Devices

If you’re trying to zoom in on the audio when you connect to a Bluetooth headset or speaker, the problem may be in codecs. Xiaomi supports various codecs like SBC, AAC, aptX and LDAC. Some are prioritize quality, while others are compatibility and volume.

In the For Developers section (which you need to activate by repeatedly clicking on the MIUI version in the About Phone section), you can find the Bluetooth Audio Codec settings. Codec switching sometimes solves the problem of quiet sound if the receiving device supports more advanced audio transmission standards.

It's also worth checking if the Absolute Volume feature is activated in the developer's settings. If this option is enabled, the volume of the phone and Bluetooth device will sync. If one device is not fully turned up, the second device will also play silently. Try changing the state of this switch.

For wired headphones with a 3.5mm or USB-C connector, the situation is similar. Make sure the audio settings are the right type of device connected. Sometimes the system misidentifies the impedance of the headphones and gives too little signal.

Frequent Questions and Challenges (FAQ)

To sum up, it’s possible to increase the sound on Xiaomi using a comprehensive approach: Start by cleaning and adjusting the equalizer, then carefully use the engineering menu if necessary. Be careful with radical amplification methods so as not to damage the hardware of your smartphone.
