How to Increase Sound in Xiaomi: The Complete Guide

Xiaomi smartphones have been leading the market for years due to their excellent price-performance ratio. However, even flagship models such as the Xiaomi 13 Ultra or POCO F5 sometimes face software limitations that prevent speakers from opening to full power. Users often notice that after another update to the MIUI or HyperOS shell, the maximum volume becomes quieter than it was before, or simply not loud enough for noisy places.

There are many reasons why the sound on your device may be quiet, including software limitations to protect your hearing, hardware implementations in budget models, and even dust accumulation in a dynamic grille, and in this article, we'll look at all the ways you can make the sound louder, from simple menu settings to the use of engineering codes.

It is important to understand that maximum amplification does not always mean better quality. Excessive volume increase by software methods can lead to wheezing, distortion and, in rare cases, overheating or failure of the speaker. So approach the setting wisely using only the proven methods described below.

Basic sound settings in MIUI and HyperOS

Before you go to complex manipulations, you need to check the standard settings of the system. Often users accidentally activate functions that limit the volume, or simply do not know about the hidden capabilities of the equalizer. In the shells from Xiaomi, a separate module is responsible for the sound, which can be configured flexibly.

Go to the Settings menu and select Sound and Vibration. This is the general volume slider, but we're interested in the Sound Quality and Effects section (or just EQUALIZER). This section often has the default mode "Original" or "Balanced" mode, which does not give maximum return. Try to switch to Clear or Power Bass mode, which will visually raise the output level.

The Mi Sound Enhancer feature is worth noting, but it automatically adjusts the frequencies to the earphones connected, but it can work with the built-in speakers. If this option is on, try turning it off or activating it, because it works differently on different models, such as the Redmi Note 12 and Xiaomi 14.

• 🔊 Check to see if Silence or Do Not Disturb mode is activated, which may limit media volume.
• 🎛️ Use a graphical equalizer to manually lift all frequency sliders up.
• 📱 Make sure that Bluetooth audio codecs have a high quality transmission if you use wireless headsets.

⚠️ Warning: When you manually adjust the equalizer, don’t raise all sliders to a maximum at the same time.This can cause digital distortion (clipping), making the sound unpleasant and hoarse, rather than louder.

Using an engineering menu to amplify sound

One of the most effective ways to increase the audio on Xiaomi is to access 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 amplification of audio channels. USSD-code that runs on most devices with MediaTek and Qualcomm processors.

Open the phone application (caller) and enter the code ##3646633##. If the code doesn't work, try it ##6484## or download the Engineering Mode app from the Play Market. After you log in, go to the Hardware Testing tab, then select Audio -> Here you will see a list of modes: Normal, Headset, Loudspeaker, Headset_Loudspeaker.

We're interested in Loudspeaker mode. Select it and go to Level, and you'll see a few rows (Level 0, Level 1, etc.) and columns with values (Digital, Analog, Gain), Digital or Gain is responsible for software amplification. By increasing this number, you make the sound louder.

But here's the big risk: The maximum value for 16-bit audio is 255, for other formats it may differ; exceeding the safe limit (usually above 200-220) can burn the speaker physically; change the values Step-by-step, checking the result after each change with the Set button.

Third-party amplifiers

If you're messing with the engineering menu, Google Play apps come to the rescue, and they act as a software layer on top of the system mixer, amplifying the signal before it's sent to the DAC, which is safer for hardware, but can consume more battery.

One of the most popular solutions is the Volume Booster GOODEV application, which has a simple one-amplification slider interface, and it works by software to raise the signal level above the standard 100%. Another powerful tool is Bass Booster & Equalizer, which not only raises the volume, but also allows you to adjust the frequency balance.

When using programs such as Super Volume Booster, it is important to ensure that the gain does not exceed 20-30%. Higher values will cause the speaker to “choke” and the sound will become deaf.

• 🚀 Volume Booster – a simple application for quick gain without unnecessary settings.
• 🎚️ Equalizer FX — professional instrument with presets for different genres of music.
• 🔊 Boom: Bass Booster – algorithmic amplification of bass and overall volume with the 3D-effect.

⚠️ Warning: Installing third-party amplifiers on devices with the already configured Dolby Atmos system can cause driver conflict, which will lead to the complete disappearance of sound.

Activation of Dolby Atmos and Hi-Res Audio

Many modern Xiaomi smartphones, especially the Mi and Xiaomi series, are licensed with surround sound technology. However, by default they can be turned off or work in a gentle mode. Turning on these features not only improves quality, but often subjectively makes the sound louder and more saturated.

To activate, go to Settings -> Sound and Vibration -> Sound Quality and Effects. Find the Dolby Atmos switch. From the menu that opens, select the Auto or Video profile if you watch movies. Also pay attention to the Hi-Res Audio settings. The inclusion of this mode allows you to play audio without compression, which unlocks the potential of the speakers.

In some regions or firmware (e.g. China’s Global ROM), these features may be hidden, and unlocking them sometimes requires changing the region in the phone’s settings to India or Singapore, where licensing agreements allow full functionality of the audio subsystem to be activated.

Cleaning the speakers and removing physical obstacles

Often the problem with quiet sound is not the software, but the mud. The smartphone is always in your pocket, where it collects pile, dust and small debris. The speaker grid gets clogged, and the sound wave just has nowhere to go, making the sound quiet and deaf.

To clean, use a soft toothbrush with dry bristles. Carefully, without pressing hard, walk along the speaker hole, sweeping the dust out. You can use a sticky tape (scotch) with your sticky side to the net to pull out the villi. You can use compressed air, but only with short "puffs" and not bring the balloon close to the inside, so as not to drive moisture inside.

Also check if the phone has a case that covers part of the sound hole. Cheap silicone cases often have inaccurate cutouts that can cover up to 30% of the speaker area, which critically affects the volume.

Set up sound codecs for Bluetooth

If the quiet sound problem is relevant when connecting wireless headphones or speakers, it could be the data codec. By default, Android can choose a low-bitrate codec to save power, which limits dynamic range and volume.

To change this, you need to activate the developer menu. Go to Settings -> About Phone and quickly click on the build number 7 times (MIUI Version). After that, the menu will appear Advanced Settings -> For developers. Find the section "Bluetooth Audio Codec".

You can choose a better codec, like aptX HD, LDAC or aptX Adaptive, if your headphones support them. These codecs transmit more data, allowing the device to better control volume and frequencies. However, it is worth remembering that using LDAC can drain the battery of a smartphone faster.

💡

If after changing the codec, the sound is completely lost, just restart Bluetooth or the smartphone itself - the system must re-confirm the connection protocol.
