How Xiaomi sounds: full instructions for setting the sound on smartphones and smart technology

When it comes to sound on Xiaomi devices, many users face typical problems: too quiet speaker, distorted low frequencies or uncomfortable equalizer settings, and few people know that even the budget models of the Mi and Redmi smartphones hide advanced tools for fine-tuning audio – from built-in presets to manual frequency adjustment through an engineering menu.

In this article, we’ll not only break down the basic audio settings in Settings → Sound and Vibration, but also the hidden features that the manufacturer doesn’t advertise. You’ll learn how to make the music on the Xiaomi 13 Ultra sound like premium acoustics, why Redmi Note 12 speakers can “hrill” at maximum volume, and how to tune the sound on Xiaomi TV for perfect theatrical effect.

Basic sound settings on Xiaomi smartphones

To start with, the obvious is that most users don't even look at the audio settings section, limiting themselves to volume control with side buttons, and yet, the standard MIUI interface has hidden tools that can dramatically change the sound.

Go to Settings → Sound and vibration.

• 🔊 Equalizer - built-in 5-band proofreader with presets (Bas, Rock, Jazz, etc.) On models with Qualcomm Snapdragon 8 Gen 2 (for example, Xiaomi 14), an extended mode with 10 bands is available.
• 🎧 Adaptive sound – a feature that automatically adjusts the frequencies to the earphones used (works only with original Xiaomi accessories).
• 🔇 Don’t worry – you can set exceptions for alarm clocks and notifications from specific apps (for example, WhatsApp calls even in silent mode).
• 🔄 Monosound is a useful option for people with hearing problems, combining stereo sound into one channel.

Note the audio quality option here, you can turn on the option “High audio quality for Bluetooth”. This is especially true for owners of wireless headphones Xiaomi Buds 4 Pro or Redmi Buds 5, as the default smartphone transmits audio in compressed SBC format, not AAC or aptX.

💡

If the sound is intermittent after the headphones are connected, try turning off the "Absolute Volume" option in Bluetooth settings, a feature that often conflicts with the firmware of some accessories.

Hidden functions of sound: engineering menu and ADB-team

For those who are willing to go beyond standard settings, Xiaomi provides access to hidden settings through an engineering menu. On models with a MediaTek processor (for example, Redmi 12C), this method allows you to increase the volume of speakers by 15-20% without the risk of damage to the equipment.

To get into the engineering menu:

1. Open the Phone app.
2. Enter ##36446337## (for MediaTek) or #4636## (for Snapdragon).
3. Go to the Hardware Testing → Audio section.

Here you will find tests for all audio devices: speakers, microphones, 3.5mm connector (if any). For example, in the LoudSpeaker menu you can manually set the values for Max Vol (maximum volume) and Min Vol (minimum). Be careful: setting the values above the factory values can lead to distortion of the sound.

For advanced users, there is another way to fine-tune it through ADB. For example, the command below includes the Dolby Atmos option on devices where it is disabled by default (does not work on all models):

adb shell settings put global audio_effects_conf_file /vendor/etc/audio_effects_dolby.conf

Xiaomi Sound Problems: Reasons and Solutions

Even Xiaomi flagship models can have sound problems, and let’s look at the most common ones and how to fix them.

The problem with robotic microphone sound during calls deserves special attention, as is typical for devices with MediaTek Helio G processors (for example, Redmi 10A), the fault is aggressive noise cancellation, which can be turned off through the engineering menu in the Mic Testing → Noise Reduction → Disable section.

💡

If after updating MIUI sound disappeared in the speaker, try resetting the settings of the application "Phone" in Settings → Applications → Application Management → Phone → Storage → Reset.

Xiaomi TVs: From Bass to Virtual Surround

Xiaomi Mi TV and Redmi Smart TV are often criticized for the "flat" sound, but the fault is not the hardware, but the factory settings. Even budget models like the Redmi TV A55 support Dolby Audio technology, which must be turned on manually.

Instructions for audio optimization on Xiaomi TV:

1. Go to Settings → Sound → Sound Modes and select Movie or Music (depending on the content).
2. Activate Dolby Audio in the Additional Settings section.
3. To enhance bass, turn on Dynamic Bass Boost (available on models from 2022).
4. If external speakers are connected, select Digital Audio Out → Auto (PCM) for minimal latency.

For owners of Xiaomi TV Q2 75" and other models with support for HDMI eARC, there is an opportunity to bring the sound to the soundbar without loss of quality.

1. Connect the soundbar to the HDMI ARC port on your TV.
2. In the audio settings, select HDMI Output → eARC.
3. Install the audio format on Bitstream (to transmit the original Dolby Digital+ signal).

Make sure your TV is connected to the internet (you need to download Dolby profiles)

Turn off all Bluetooth devices (they may interfere)

Update your firmware to the latest version (new versions of MIUI TV have improved audio driver)

Check HDMI cables for damage (especially if you use eARC)

How to improve the sound in headphones: equal to Hi-Res Audio

If you use premium headphones (such as Xiaomi FlipBuds Pro or 1MORE SonoFlow), standard MIUI settings won’t unlock their potential.

1. Install a high-resolution player app (such as Neutron Music Player or USB Audio Player PRO).
2. In the player settings, select the bit ratio of 24 bits and the sampling rate of 96 kHz (if your headphones support this).
3. Disable all system effects in Settings → Sound → Sound effects.
4. For wired headphones with a connector USB-C use OTG-Adapter with external DAC (e.g. Xiaomi Type-C to) 3.5mm Audio with built-in amplifier).

On models Xiaomi 13 Pro and newer available function LDAC – Bluetooth codec with a bitrate of up to 990 kbit / s. To activate it:

1. Connect compatible headphones (such as Sony WH-1000XM5).
2. In Bluetooth settings, select Sound Quality → Sound Priority.
3. Install the LDAC codec and select the bitrate of 909 kbps (the optimal balance between quality and stability).

💡

If the sound starts to break when using LDAC, reduce the bitrate to 660 kbit / s or go to the AAC codec. The problem is usually associated with interference in the 2.4 GHz range (Wi-Fi, microwaves).

Sound in Games: How to Get an Advantage on Xiaomi Black Shark

For gamers using Xiaomi Black Shark or POCO F5 smartphones, sound is not only an atmosphere, but also a tactical advantage. In games like PUBG Mobile or Call of Duty: Mobile, the right settings will help you hear the opponent’s footsteps or direction of shots.

Optimal settings for game sound:

• 🎮 3D-sound: Turn on the game settings (if supported) and disable all system effects in MIUI.
• 🔊 EQUALIZER: Install Preset "Game" or manually raise frequencies 2-4 kHz (responsible for footstep sounds and recharges).
• 🎧 Headphones: Use low latency models (e.g. Redmi Buds 4 Active in Game Mode").
• 🔇 Microphone: Turn off noise cancellation in Settings → Sound. → Improve your voice so that your voice is clearer.

Black Shark devices have a unique feature called Shark Space, which optimizes the sound specifically for games, to activate it:

1. Swipe down the notification bar and click on the Shark Space icon.
2. Select the Game profile.
3. Enable the Super Sound option (amplifies high frequencies for better localization of sounds).

💡

In games that support Dolby Atmos for Gaming (for example, Fortnite), the sound becomes larger if the phone settings include the option of the same name, but this increases the latency by 10-15 ms, which is critical for eSports.

Frequent questions about the sound on Xiaomi

How to Get the Perfect Sound on Xiaomi

Sound on Xiaomi devices is not only hardware, but also the right settings. Even budget models, when properly configured, can sound as good as flagships of other brands.

• 🔧 Use the equalizer and Dolby Atmos to adapt sound to the genre of content.
• 🔍 For fine-tuning, look at the engineering menu - there are hidden options that are not available in the standard interface.
• 🎧 For headphones, choose a codec. LDAC or AAC, not SBC.
• 🎮 Gamers should activate Shark Space or manual presets for better localization of sounds.

If you're still not comfortable with the sound after all the manipulations, consider buying an external DAC or soundbar, but 90 percent of the time, the problem isn't the hardware, it's the suboptimal settings.

💡

Before selling or handing over the phone for repair, reset the sound settings to the factory – this will save your personal equalizer presets from prying eyes.
