Weak sound on Xiaomi devices is a common problem that interferes with comfortable listening to music, watching videos or communicating on the phone. The reasons can be different from factory volume limits to contaminated speakers or incorrect settings. In this article, we will discuss all possible ways to increase volume, from basic system parameters to hidden functions of the engineering menu and hardware solutions.
It's important to understand that not all methods are equally safe. Some changes can lead to audio distortion, overheating of speakers or even loss of warranty. So we will describe the risks of each approach in detail and give recommendations for minimizing them. If you are an owner of a Redmi Note 12, POCO X5 or Mi 11, the instructions will be suitable for any model based on MIUI or HyperOS.
Let’s start with the simplest and safest ways, and then move on to advanced techniques for power users.
1. Checking basic sound settings
Before you resort to radical measures, make sure that the problem is not in the standard settings. Often users simply do not notice active restrictions or incorrectly configured profiles.
Open the Settings menu → Sound and vibration and check:
- 🔊 Multimedia volume level – move the slider to maximum. Some models (such as Redmi 10) have separate regulators for calls, alarms and notifications.
- 🎧 Amplify the sound in the headphones - turn on the option MI Sound Enhancer (available on the MIUI 12+). It automatically adjusts frequencies for better perception.
- 🚫 Do Not Disturb - Turn it off if it's active, sometimes it lowers the volume of notifications to a minimum.
- 🔄 Adaptive sound – disable this feature if you have it in your firmware.It automatically adjusts the volume to the surrounding noise, but often works incorrectly.
Also worth checking the sound profile in quick settings (swipe down from the top edge of the screen). Some devices (e.g. POCO F4) have separate modes Home, Outdoor and In Transport with different volume limits.
💡
If the sound is quieter after the settings change, try restarting the device, and sometimes the system audio services freeze and require restarting.
Cleaning of speakers and connectors
One of the most common causes of silent sound is contamination of speakers or a 3.5mm jack (if you have one on your model), and dust, fabric fibers, or moisture can physically block sound waves, reducing volume by 30-50%.
To clean the speakers:
- Use a soft brush (for example, to paint or clean lenses) to remove visible dust from the grille.
- For deep cleaning, a toothpick with a cotton tip dipped in alcohol (no more than 70%) is suitable. Carefully scrolle it inside the speaker holes.
- To remove moisture, place the device in a silica gel bag (shoe box bags) for 12-24 hours.
To clean the 3.5mm connector:
- 🎵 Use a dry cotton swab, slightly moistened with alcohol.
- 🔦 Illuminate the connector with a flashlight - if foreign objects are visible inside, carefully remove them with tweezers.
- 🔌 After cleaning several times connect and disconnect the headphones to remove possible oxides from the contacts.
What to do if water gets into the speaker?
If the sound hasn't improved after cleaning, the problem may be a damaged speaker membrane or detached contacts, in which case professional repairs will be required.
3.Use of the engineering menu (for experienced users)
The Engineering Mode allows you to change hidden audio settings that are not available in standard settings, a method that is suitable for users willing to risk system stability for the sake of increasing volume.
To open the engineering menu:
- Open the Phone app.
- Enter the combination: ##36446337##
- Choose Hardware Testing → Audio.
In the Audio menu, pay attention to the following parameters:
| Parameter | Recommended value | Risks. |
|---|---|---|
| Headset Loudness | 150-160 (max 255) | Sound distortion at values above 180 |
| Speaker Loudness | 120-140 (max 255) | Overheating of the speaker with prolonged use |
| Mic Gain | 0-5 (for improved recording) | Increased noise levels at high values |
| Media Volume Steps | 15-25 (standard: 15) | Too much importance will make regulation inaccurate |
Changing Speaker Loudness settings above 160 can cause physical damage to the speaker on models with small speakers (for example, Redmi 9A or POCO M4 Pro).
Yes, to turn up the volume.|Yes, for other purposes.|No, I'm afraid to break my phone.|I don't know what that is.-->
When you change the settings, restart the device. If the sound gets worse (wheezing or distortion), return the values to the standard and check the speakers for damage.
4.Applicants for sound amplification
If the system settings don't work, you can use third-party apps, which work on two principles: either amplify the sound programmatically (via equalizer), or bypass the limitations of Android.
Top.-5 Verified applications for Xiaomi:
- 🎛️ Equalizer FX — It's a free equalizer with presets for different genres of music, and it allows you to turn up the volume by 20-30% distortionless.
- 🔊 Volume Booster GOODEV — It can amplify up to 60% of the sound (requires root rights for maximum effect). MIUI HyperOS.
- 🎧 ViPER4Android — Professional audio processor with surround sound support requires driver installation via Magisk.
- 📱 Precise Volume – allows you to adjust the volume levels more accurately (up to 100 steps instead of the standard 15 steps).
- 🔄 Wavelet – automatically adjusts the sound to your headphones (there are databases for popular models).
Installation of ViPER4Android requires additional steps:
Download APK official website|Install Magisk and get root rights|Download and install the driver ViPER4Android via Magisk|Reset the device|Set up a profile in the ViPER application-->
Warning: applications that require root may disrupt MIUI, especially on new firmware (HyperOS 1.0+).
💡
Rootless apps (like Equalizer FX) are safe, but their effectiveness is limited by Android system limits.
5 Hardware solutions: replacement of speakers and amplifiers
If software methods didn't work, the problem could be physical wear on the speakers or a weak amp, and then the only thing that would help is to replace the components.
Common hardware problems:
- 🔇 Wearing of the membrane dynamics - over time, the membrane loses elasticity, which leads to a decrease in volume and wheezing.
- 🔌 Oxidation of contacts – especially important after moisture or prolonged use.
- 🔋 Weak sound amplifier – on budget models (for example, Redmi) 8A) The booster may not be able to handle the load.
Cost of repairs in service centers:
| Service | Cost (₽) | Repair time |
|---|---|---|
| Replacement of the lower speaker | 1 200 — 2 500 | 1-2 hours |
| Replacement of the upper speaker (conversational) | 1 500 — 3 000 | 1 hour |
| Replacement of sound amplifier | 2 000 — 4 500 | 2-3 hours |
| Cleaning contacts (without replacement) | 500 — 1 200 | 30 minutes. |
To replace the speaker on Xiaomi models, you will need:
- 🛠️ Set of screwdrivers (cross, flat, flat, T3-T5)
- 🔥 Hazel for softening glue (temperature) 60-80°C)
- 🧲 Screen removal suction cup (for models with adhesive attachment)
- 🔌 Multimeter for checking contacts

Remember, self-repairing is insecure and can cause additional damage (such as damage to the screen plume). If you are not sure about your skills, you should contact the service center.
6. Features of the audio setting on Xiaomi TV
Xiaomi Mi TV and Redmi Smart TV devices also often suffer from quiet sound, and the reasons for this can be different from the wrong HDMI ARC settings to firmware restrictions.
How to increase volume on Xiaomi TV:
- Go to Settings → Sound → Sound Modes and select Cinema or Music.
- Activate Dolby Audio and DTS-HD in the Settings menu → Sound → Advanced settings.
- If the TV is connected to the sound bar via HDMI ARC, check the audio output settings: Settings → Sound → HDMI Output → ARC.
- For Android TV models, install the Equalizer for Android TV app from Google Play.
Xiaomi TVs have a hidden menu for calibrating the sound:
- On the remote, press sequentially: Menu → Settings → Support → Service menu (code: 12345).
- Go to Audio Settings → Speaker Test and check the balance between left and right speakers.
- In the Volume Limit menu, you can increase the maximum volume threshold to 100% (standard: 80%).
💡
On Xiaomi TVs with diagonals above 55 inches (such as the Mi TV Q2 75), a volume increase above 90% can cause audio distortion due to the limitations of the built-in speakers.
7.Alternative methods: Bluetooth devices and external speakers
If you can't turn up the volume on the device, consider using external audio systems, which not only solves the problem of quiet sound, but also improves the quality of the sound.
The best options for Xiaomi:
