The sound on Xiaomi smartphones is one of the most common causes of user discontent, with speakers running too quiet, the balance between high and low frequencies broken, the volume dropped dramatically after the MIUI update, and there may be dozens of reasons, from a trivial error in settings to hardware malfunctions, but in 90% of cases, the problem can be solved software-free without going to the service center.
In this article, we’ll look at all the possible ways to turn up the volume on Xiaomi, Redmi and POCO, from standard MIUI tools to hidden engineering menu features, how to customize the sound to specific scenarios (music, calls, games), which apps will help you get the most out of the speakers, and what to do if the sound is gone after the update, and at the end, answer to the most common questions on the topic.
1. Basic sound settings in MIUI
Start by checking the obvious. Often users miss basic parameters that can be changed in a few taps. Open Settings → Sound and vibration and pay attention to the following points:
- 🔊 Media volume - regulates the sound in applications (YouTube, Spotify, games.
- 📞 Call volume is a separate regulator for incoming calls. In some models (Redmi Note 10 Pro, Xiaomi) 11T) There is an option to "High up the volume in your pocket".
- 🎵 Sound quality in new versions MIUI 14+ You got Equalizer presets (Bas, Rock, Jazz.
- 🔇 Do not disturb – make sure the mode is not activated (especially if the sound is suddenly gone).
If you change the volume after you change the parameters, move to the next section. On models with stereo speakers (Xiaomi 13 Pro, POCO F5) check the balance between the top and bottom speakers - sometimes one of them turns off due to contamination of the grille.
2. Hidden sound settings through the engineering menu
Engineering Mode is a powerful tool for fine-tuning hardware components, including sound. Careful: improper changes can cause malfunctions. We recommend using this method only if standard settings have not worked.
To open the engineering menu:
- Open the Phone app.
- Enter ##36446337## (for MediaTek) or #4636## (for Qualcomm Snapdragon).
- Go to the Hardware Testing → Audio section.
Here you will see a list of parameters that can be changed:
| Parameter | Recommended value | What regulates |
|---|---|---|
| Speaker Mode | Normal or Loud | Total volume level of the speaker |
| Headset Mode | Normal | Loudness with connected headphones |
| Mic Gain | 0-3 (not higher!) | Microphone sensitivity |
| Max Vol | 150-160 | Maximum volume level (default 100) |
⚠️ Warning: Do not set the Max Vol above 160, which can cause sound distortion and damage to speakers at long high loads. 9A, POCO M3) risk!
What to do if the engineering menu does not open?
3. Sound amplification applications
If the system settings don't work, try third-party utilities. They work on two principles:
- 🔧 Sound amplifiers – increase volume due to processing algorithms (risk of distortion).
- 🎛️ Equators – adjust the frequency balance, making the sound “louder” by raising certain ranges.
Top.-3 tested applications:
- Volume Booster GOODEV is a simple booster with pre-profiles for music, video and games. Supports Xiaomi on Android 10-14. Minus: advertising in the free version.
- Equalizer FX is a 10-band equalizer with presets for different genres, and you can save your own settings for specific applications (for example, separately for Spotify and YouTube).
- ViPER4Android — It's the most powerful audiophile solution, and it requires a Magisk root installation, and it allows you to configure virtual environments, compressors, limiters, and even simulations. 3D-sound.
⚠️ Attention: Amplifiers can cause clipping (torture of sound at high volume); if you hear wheezing, reduce the gain or turn off the application. On models with weak speakers (Redmi). 8A, POCO C31) risk of damage.
Install the app from an official source (Google Play or 4PDA)
Check the current volume in the MIUI settings (should be 70-80%)
Start with a minimum gain level (5-10%)
Test the sound on different tracks (speech, bass music, high frequencies)

4.Sound problems after MIUI update
MIUI updates often bring not only new features, but also sound bugs.
- 🔇 The sound is gone (the speakers are not working).
- 📉 The volume has dropped sharply (even at maximum quiet).
- 🔊 The sound is distorted (wheezing, interruptions).
- 🎧 Problems with Bluetooth headphones only.
Decisions of the order:
- Reboot is trivial, but it works 30 percent of the time. Press the power button and select Reboot.
- Cache Cleanup: Go to Settings → Apps → App Management. Find Media and Bluetooth, clear the cache. For Xiaomi with Android 12+, also clear the Android System WebView cache.
- Resetting sound settings: Settings → System → Resetting settings → Resetting sound settings This item appeared in MIUI 13 and later.
- Update rollback – if the issue has appeared after the last update, try rolling back: Settings → About Phone → System Update → Three points (menu) → Select the service pack Select the previous version of MIUI (if saved in the device memory).
If nothing helps, check the FAQ section – it’s cleared out specific cases for different models.
1. Activate the developer mode (7 taps by Build Number in About Phone).
2. Go to Settings → Additional → For developers.
3. Find the option to Turn off the absolute volume of Bluetooth and turn it on.-->
5. Hardware causes of silent sound
If the software methods didn't work, the problem could be the hardware.
- 🧹 Contamination of speakers – dust and pile block sound waves, especially for models with a lower speaker (Redmi Note 9, POCO X3).
- 💧 Moisture intrusion – even after complete drying, oxidation of contacts can worsen sound.
- 🔌 Trail damage is a common problem after falling or disassembling the phone.
- 🔋 Wear speaker - over time, the membrane loses elasticity (typical for phones older than 3 years).
How to diagnose:
- Speaker test: ##0673## or #0289## (on some Xiaomi models), if one of the speakers is not making sound, the hardware problem is.
- Pollution check: flash a flashlight into the speaker's grille. Do you see fibers or dust? Clean carefully with a soft brush (do not use toothpicks!).
- Test with headphones: if the sound in the headphones is normal, and in the speakers is quiet, the problem is with the speakers or their connection.
Cost of repairs in service centers:
| Type of repair | Average price (₽) | Repair time |
|---|---|---|
| Cleaning the speakers | 500–1 200 | 30-60 minutes |
| Replacement of the lower speaker | 1 500–3 000 | 1-2 hours |
| Replacement of the plume speaker | 2 000–4 500 | 2-3 hours |
| Repairs after moisture | 3 000–8 000 | 1-3 days |
⚠️ Warning: If you decide to clean the speakers yourself, do not use alcohol or liquids - they can damage the membrane.The best option is a dry soft brush (for example, for camera lenses) or a compressed air balloon (keep 10 cm away!).
6. Sound optimization for specific scenarios
There's no universal audio setting, and what's good for music may not be good for calls, and we'll sort out the optimal configurations for different tasks.
🎮 Games
In games, spatial sound and clear reproduction of high frequencies (steps, shots) are important.
- Turn off Dolby Atmos (if any) – it adds a delay.
- In the engineering menu, set Speaker Mode = Loud.
- Use low latency headphones (e.g. Xiaomi Buds 4 Pro).
🎵 Music.
For music, the balance of frequencies is critical.
- Activate Dolby Atmos (in Settings → Sound → Sound Quality).
- In Equalizer FX, select Preset Bass or manually configure: 60Hz: +4 dB 230Hz: +2 dB 910Hz: 0 dB 14KHz: +1 dB
- For Spotify, enable High quality streaming in the application settings.
📞 Calls.
If the interviewer is not heard well:
- Increase the Mic Gain in the Engineering menu to 2-3.
- Turn off noise cancellation in Settings → Sound → Improve voice.
- Use a headset – the built-in microphone of headphones is often better than the main one.
💡
For models with Qualcomm Snapdragon (for example, Xiaomi 12 Pro, POCO F4), AptX Adaptive is available – turn it on in Bluetooth settings for better sound in wireless headphones.
