Volume control on Xiaomi devices seems like a simple task — until you encounter quiet sound in speakers, uneven volume in different applications or sudden silence after an update. Unlike other brands, Xiaomi smartphones and smart speakers have unique features: separate sliders for multimedia and alarm clock, adaptive sound MI Sound Enhancer, and on some models even hidden engineering settings for advanced users.
This article will not just tell you how to turn up or down the volume, but we'll explain why the sound can disappear at half the scale, how to get around the limitations. EU-The versions of smartphones, where to find hidden settings to strengthen the bass, and what to do if the speaker suddenly stopped working after a fall, and also compare the volume of flagships (Xiaomi 14 Ultra) and budget models (Redmi Note 12) in real tests.
Basic volume setting: buttons and scale
The most obvious way is to have physical buttons on the side of a smartphone, and on Xiaomi, the top button increases volume, the bottom button decreases volume, but there are some nuances.
- 🔊 Three types of volume: When you press the buttons, you get a scale with three icons -- Multimedia (music, video), Calls (call, notifications), Alarm. Swipe left/right between them.
- 📱 Block buttons: If the volume does not change, check if Do Not Disturb or Game Turbo is activated (they can block the adjustment).
- 🔇 Quiet mode: on some firmware (MIUI 14+) Long pressing the volume button down puts the phone in silent mode.
On Xiaomi smart speakers (for example, Mi Smart Speaker), adjustment is carried out:
- 🎛️ Touch buttons +/– top-panel.
- 📱 Through the Mi Home app (Device section) → Sound settings).
- 🗣️ Voice command: “OK, Google, turn 30 percent louder” (only works when paired with Google Assistant).
Advanced sound settings in MIUI
If the basic adjustment isn't enough, look at Settings → Sound and vibration. There are features that many people don't know about.
- 🎧 Adaptive sound: included in the settings → Sound. → MI Sound Enhancer. Analyzes the acoustics of the room and automatically adjusts the equalizer. Works only on flagships (Xiaomi). 13/14 series, MIX Fold).
- 🔊 Volume up: Option to Increase Volume Speaker (available on the POCO F5, Redmi K60). Increases the maximum volume by 10-15%, but can cause distortion.
- 📊 Equator: In Settings → Sound. → Select Preset (Rock, Pop, Jazz) or manually adjust sliders for low/medium/high frequencies.
On Xiaomi with stereo speakers (Xiaomi 12 Pro, Redmi K50 Gaming), the Stereo effect option will appear in the same menu, which expands the sound scene, but reduces the overall volume by 5-7 dB.

Engineering menu: hidden volume settings
For power users willing to take risks (missteps can damage speakers!), there is an engineering menu that allows you to fine-tune the volume levels for each scenario:
- Open the Phone app and enter the code: ##36446337##
- Go to the Hardware Testing → Audio section.
- Select LoudSpeaker Mode (for the main speaker) or Headset Mode (for headphones).
- In the Value field, enter a number from 0 (minimum) to 160 (maximum), the limit for most models is 140 (exceeding is fraught with distortion).
⚠️
Note: On EU-based models (Xiaomi Mi 11 Lite, Redmi Note 10 Pro), the maximum value in the engineering menu is artificially lowered to 120 due to European noise standards.
In the engineering menu, you can also test the speakers for damage:
- 🔧 Speaker Test – checks left/right speaker (on stereo models).
- 🎵 Loopback Test – Diagnoses microphone and speaker at the same time.
What happens if you put the maximum value (160) in the engineering menu?
Volume problems and their solutions
If the speaker is quieter or the sound is lost at a certain volume level, the reasons may be both software and hardware.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The sound goes off at 50% volume. | The protection against distortion (often on the Redmi 9/10 series) worked | Turn off MI Sound Enhancer in the sound settings |
| A quiet sound in games, but normal in music | Limitation of the Gaming Turbo mode | Turn off Sound Optimization in the Game Settings |
| The speaker cracks at maximum volume | Damage to the membrane or dust under the net | Cleaning with alcohol or replacing the speaker (in the service) |
| Uneven volume in stereo speakers | Unbalanced after the MIUI update | Reset the sound settings to factory |
⚠️
Warning: If the sound became quiet or wheezing after the fall of the smartphone, do not try to increase the volume software - this can bring the speaker to complete failure. In 80% of cases, only a replacement module helps (cost for Xiaomi - from 800 to 2500) ₽ model-wise).
💡
Before contacting the service, check if the speaker mesh is filled with dust. Clean it carefully with a soft toothbrush (do not use sharp objects!).
Comparison of volume on different Xiaomi models
The loudness of the speakers varies not only from model to model, but also from regional firmware, and we tested several devices in the laboratory (indoor noise level is 30 dB):
| Model | Max. Volume (dB) | Type of speaker | Features |
|---|---|---|---|
| Xiaomi 14 Ultra | 88 dB | Stereo (Harman Kardon) | The cleanest sound, but the bass is weaker than the POCO F5 |
| POCO F5 | 91 dB | Mono (enhanced) | Highest volume, but distortion at maximum |
| Redmi Note 12 Pro+ | 85 dB | stereo | Good balance, but quieter flagships by 10-15% |
| Xiaomi Mi 11 Lite (EU) | 80 dB | Mono | Restriction on EU-standards (max value in the engineering menu - 120) |
Xiaomi smartphones with support for Dolby Atmos (Xiaomi) 13T Pro, Redmi K60 Pro) In Movie mode, automatically reduce the volume by 3-5 dB to improve detail. → Sound. → Dolby Atmos → Profile.
Volume setting on Xiaomi smart devices (columns, TV, headphones)
In addition to smartphones, the brand produces smart speakers, TVs and headphones - each has its own nuances of sound regulation.
Smart speakers Mi Smart Speaker
Loudness is adjusted:
- 🎛️ Physical buttons on the device (step 5%).
- 📱 Through Mi Home: The Device → Settings → Loudness by default (you can set a limit for children).
- 🗣️ Voice: OK, Google, set the volume to 70%».
Mi TV and Redmi TV
Features:
- 🔊 Volume Autocontrol: C Settings → Sound. → Intelligent volume is turned on adaptation to the genre of content (in the news the sound is quieter, in action movies – louder).
- 🎚️ Equalizer: Presets Sport, Film, Music, and Manual Customization are available.
- 🔇 Night mode: reduces the volume of explosions and increases the voice of the announcer (included in Settings) → Sound. → Night mode).
Mi Earbuds and Redmi Buds headphones
Adjustment depends on the model:
- 🎧 Mi Earbuds 3 Pro: Support LDAC (Included in Bluetooth settings) increases detail, but can reduce volume by 10-20%.
- 🔗 Redmi Buds 4 Active: equalizer with 10 presets is available in the Mi Earphones app.
💡
On smart Xiaomi devices (columns, TV) often triggered volume limit on time. For example, after 22:00 the speaker automatically reduces the sound to 50% — this is the setting Quiet hour in Mi Home.
How to turn up the volume without risk to speakers
If standard methods aren’t enough, but you don’t want to spoil the speakers, try these safe ways:
- 🎵 Amplifiers: Volume Booster (boosts up by 20–30%, but doesn’t work on all firmware). FX (It allows you to raise low frequencies without distortion).
- 🔧 Change the file mixer_paths.xml (For root users only: In this file (path: /vendor/etc/mixer_paths.xml) You have a volume limit. <path name="speaker"> <ctl name="RX1 Digital Volume" value="84"/> limiting 84. You can zoom in. 90, higher!
- 📦 Firmware replacement: EU-Smartphone versions reflashing on Global ROM It removes the volume limit, but it voids the warranty!
⚠️
Note: Amplifiers often use bypassing system constraints through AudioFX. This can lead to conflicts with MIUI, especially on firmware newer than MIUI 13. If after installing such software, the sound begins to break, clear the cache of the Settings application → Applications → Application Management → AudioFX → Storage → Clear the cache.
