If you are a Xiaomi Poco smartphone owner and you are facing a problem with quiet sound in headphones, this article will help you understand the reasons and find a solution. Low volume can be associated with hardware limitations (for example, a weak amplifier in budget models Poco M or Poco C), and with software settings MIUI, which artificially lower the sound level to protect hearing. It is important to understand that not all methods are equally safe: some can lead to distortion of sound or even damage the speakers.
In this article, we will consider 7 Proven ways to increase volume, from basic settings in the phone menu to advanced tweaks through the engineering menu and third-party utilities. X3/X4/X5, Poco F3/F4/F5 POCO M4/M5/M6, because their hardware platform (e.g. Snapdragon chips) 7xx/8xx) It affects the options available, and we'll also see why, after the update, MIUI 14/15 The sound could be quieter and how to fix it.
1. Check basic sound settings in MIUI
Before you resort to radical measures, make sure that the problem is not the standard settings. Xiaomi Poco often gets confused after connecting new headphones or updating the system.
- 🔊 Multimedia Volume Level: Press the physical volume button and make sure that the Multimedia slider (not the Call or Alarm) is raised to maximum.
- 🎧 Headphone Profile: In some models (e.g. Poco) F3 GT) MIUI Automatically activates Safe Loud Limiting mode. Turn it off in Settings. → Sound. → Safe sound.
- 🔄 Connection Type: If you use Bluetooth headphones, check the codec in Settings → Bluetooth → ⚙️ near-device → Codec. Optimal options: AAC (Apple AirPods or aptX (Sony, Sennheiser).
On Poco models with a Snapdragon 8xx chip (like the Poco F5 Pro), the MIUI 15 may trigger a volume limit due to Dolby Atmos certification. To remove it, you need to turn off Dolby in the audio settings.

2.Using uniform gain (EQ and Dolby Atmos)
The MIUI equalizer and Dolby Atmos technology can significantly improve sound perception without increasing actual volume, a technique particularly useful for the Poco X3 Pro or Poco M4 Pro models, where hardware constraints prevent the level from being elevated above a safe threshold.
How to set up:
- Go to Settings → Sound → Sound quality and effects.
- Turn on the Equator and select the Bass or Rock preset – they amplify the low and medium frequencies, creating the illusion of higher volume.
- Activate Dolby Atmos and select Movie or Music profile. The Poco F4 GT has Game mode available that enhances dynamic range.
| Model Poco | Dolby-supported | Recommended profile |
|---|---|---|
| Poco X3/X3 Pro | Dolby Atmos (Basic Version) | Music. |
| Poco F3/F4/F5 | Dolby Atmos (full version) | Movies or Games |
| Poco M4/M5/M6 | Just an equaliser. | Bass or User (enhance 250-500 Hz) |
⚠️ Note: On some firmware (for example, MIUI 14 Global) Dolby Atmos may conflict with Bluetooth codecs. If the sound became intermittent after Dolby was turned on, go back to the standard settings.
3. Engineering menu: hidden volume settings
For power users, there is a way to increase volume through an engineering menu (Engineer Mode), which works on most Poco models, but requires caution: incorrect settings can lead to distortion of the sound or damage to the speakers.
Instructions:
- Open the Phone app and enter the combination: ##36446337###
- Go to Hardware Testing → Audio → Headset Mode.
- In the Max Vol field, change the value from 144 to 155 (maximum 160, but not recommended!).
- Save the settings and restart the phone.
What to do if the engineering menu is not opened?
⚠️ Note: On models with Snapdragon chips (e.g. Poco) X5 Pro) the change in the parameters in the engineering menu may reset after the update MIUI. To fix the settings, use the BuildProp Editor app and add a string:
ro.audio.headset.volume=155Standard settings MIUI|Equalizer/Dolby Atmos|Engineering menu|Application Party (ViPER4Android)|I haven't tried anything-->
Side of sound amplification application
If the built-in tools don't help, you can use specialized applications.
- 🎛️ ViPER4Android — It's a powerful sound processor with equalizer, compressor and amplifier, and it requires root rights for full functionality, but it works without them. MIUI 13+.
- 🔊 Volume Booster is a simple volume booster with pre-tuned headphone profiles. Suitable for Poco M series models.
- 🎧 Wavelet – an application with support LDAC And aptX, which optimizes the sound for Bluetooth headphones, which is especially useful for Poco. F3/F4 Snapdragon-chip 870/888.
Installation of ViPER4Android (the most popular option):
- Download APK from ViPER's official website (avoid pirated versions!).
- Install the ViPER4Android FX driver via Magisk (if there is a root) or use the MIUI workaround:
- In the application settings, activate Master Limiter (set 0 dB) and Volume Boost (maximum +6 dB).
💡
If the sound is gone after installing ViPER4Android, restart the phone and clear the app cache in the MIUI settings. Some firmware requires you to disable Dolby Atmos before using ViPER.
5. Hardware causes of silent sound and their elimination
If the software methods fail, the problem may lie in the hardware, and here are the most common reasons for Xiaomi Poco smartphones:
- 🔌 3.5mm contaminated connector (for jack models, such as Poco) X3 NFC). Clean it with a wooden toothpick soaked in alcohol.
- 🔋 Weak sound amplifier in budget models (Poco) C31/C40). It is only decided by the external USB-C an amplifier (e.g. FiiO) KA3).
- 🔊 A damaged audio chip plume (a common problem after falls) is diagnosed at a service center.
- 📱 Wearing the earphone speakers. Check them on another device.
⚠️ Attention: On Poco models F5 and newer (with port) USB-C) There's a lot of bad contact in the connector, and if you have a sound, it disappears when you move the cable, you need to change the connector, and the average cost of repairs in service centers is 1,500 to 2,500. ₽.
6. Features for Bluetooth headphones
If you use Bluetooth headphones (such as Xiaomi Buds 4 or Redmi Buds 5), low volume may be due to your codec or connection profile settings.
- B Settings → Bluetooth press on ⚙️ Next to your headphones and select Audio Profile → Telephone calls and multimedia.
- Activate the option Absolute Volume – this synchronizes the volume levels on the phone and headphones.
- For headphones with LDAC support (e.g. Sony WH-1000XM5), install the LDAC codec in MIUI and select the quality of 990 kbit/s (in the Bluetooth device settings).
| Codec | Max. bitrate. | Delay. | Recommendations |
|---|---|---|---|
| SBC | 328 kbps | Tall. | Standard, but not optimal |
| AAC | 250 kbps | Medium | Better for Apple AirPods |
| aptX | 352 kbps | Low. | Perfect for Sennheiser, Bose |
| LDAC | 990 kbps | Very low. | Best Hi-Res audio (requires headphone support) |
⚠️ Attention: On Poco X5 5G and other models with Snapdragon chip 6xx codec LDAC If the sound starts to break, switch to aptX or AAC.
7. Resetting the sound settings to factory
If all previous methods have failed, the last step may be to reset the audio settings, which will help if the problem is caused by a failure in the MIUI configuration files (for example, after a failed update or custom firmware installation).
How to reset:
- Go to Settings → Applications → Application Management.
- Click on the three dots in the top right corner and select Reset app settings.
- Confirm the reset and restart the phone.
After the reboot:
- 🔄 Reconnect the headphones and check the volume.
- 🔊 Set up the equalizer and Dolby Atmos from scratch.
- 📱 If the problem persists, perform a hard reset via Settings. → The phone. → Setting reset. Attention: it will delete all data!
💡
Resetting your audio settings is a last resort, and before that, be sure to check the headphones on another device and update your MIUI to the latest version.
