How to reduce the volume of the speaker during a call on Xiaomi Poco X3 Pro: 5 working methods

Xiaomi Poco X3 Pro is a popular smartphone with a powerful speaker that can sometimes seem too loud during phone calls. The problem is especially relevant for users who often communicate in noisy rooms or use a headset with high sensitivity. In this article, we will discuss all possible ways to reduce the volume of the conversational speaker, including hidden settings and engineering menus.

It's important to understand that the volume control during a call is different from the media sound or notification settings. The manufacturer often limits the range of changes in standard settings, but there are workarounds. We tested all methods on the Poco X3 Pro with MIUI 12.5 firmware and MIUI 13 — the results are relevant for both versions.

If you're having a problem hearing you too loud, or hearing you too loud, or hearing you in the speaker is cutting your hearing, this is a great way to go, and let's start with the simplest of ways and move on to advanced settings.

1. Standard volume control through buttons

The most obvious way is to use physical volume buttons while calling. On the Xiaomi Poco X3 Pro, this works as follows:

• 📞 During an active call, press the Volume Up/down button on the sidebar.
• 🔊 A slider will appear on the screen with the inscription “Strongness of the call” – move it to the left.
• 🔇 If the slider is already at a minimum, but the sound is still loud, proceed to the following methods.

Note that on some MIUI firmware, the slider may reset after the call is complete. To fix the settings, you will need to change the system settings (more about this below).

⚠️ Warning: If the volume is reset the next time you call, the system has activated Adaptive Volume.

2.Switching off adaptive volume and equalizer

The adaptive volume function in MIUI automatically adjusts the sound level to the environment, sometimes causing the speaker to start operating at maximum power even in a quiet room, to turn it off:

1. Open the Settings. → Sound and vibration.
2. Scroll down and find the Adaptive Volume section.
3. Turn off the switch next to this function.
4. Go back and select Equalizer → install the preset “Normal” or “Voice”.

Also check the voice amplification settings in the same section. If the option is active, it can artificially raise the volume of the interlocutor. On the Poco X3 Pro, this feature is often turned on by default.

💡

If the sound becomes too quiet after switching off the adaptive volume, try manually adjusting the equalizer by increasing the frequencies in the range of 1-3 kHz - this will improve the intelligibility of the voice without increasing the overall volume.

3. Hidden sound settings via USSD codes

Xiaomi has hidden menus that allow you to fine-tune the sound settings. The following commands are suitable for the Poco X3 Pro:

• 📱 Enter the phone code in the app: ##36446337##
• 🔧 The Engineering Mode menu will open. Select Hardware Testing. → Audio".
• 🎧 In the Receiver section, set the value of Volume to 80–100 (often 120–140 by default).
• 💾 Save the settings and restart the phone.

If the code doesn’t work, try an alternative:

##4636##

In the menu that opens, select Phone Information → Network Selection → Network Type. There are no direct audio settings, but sometimes resetting network settings helps stabilize the speaker.

⚠️ Warning: Changes in the engineering menu can affect communication quality. If there is interference or echo after adjustment, return the values to factory (120-140 for Receiver Volume).

4. Use of third-party applications

If system methods do not help, you can use third-party utilities. For the Poco X3 Pro, you can:

Check reviews before installing apps – some utilities may not work properly on MIUI 13. For example, Volume Booster sometimes resets settings after rebooting.

5. editing system files (for advanced users)

If none of the methods worked, there is still the option of manually editing system files. X3 Pro path to the sound configuration file: /vendor/etc/mixer_paths_tasha.xml. Changing this file requires root rights or access through ADB.

Instructions for users with root:

1. Install a file manager with root support (such as Root Explorer).
2. Cross the path. /vendor/etc/ and find the file. mixer_paths_tasha.xml.
3. Make a backup of the file.
4. Open the file in the text editor and find the lines with the parameters: <path name="handset-mic"> <ctl name="RX1 Digital Volume" value="84" /> Reduce the value to 70–75.
5. Save the changes and restart the phone.

Without root rights, you can try editing a file through ADB:

adb pull /vendor/etc/mixer_paths_tasha.xml

Edit the file on the PC



adb push mixer_paths_tasha.xml /vendor/etc/




adb reboot

⚠️ Warning: Incorrect editing of system files can lead to loss of sound or a cyclical reboot of the device.If you are not sure about your actions, use other methods.

💡

Editing mixer_paths_tasha.xml — The most efficient way, but also the most risky way, is recommended only for users with root and backup experience.

6. Hardware causes of high volume

If the software methods didn't help, the problem could be the hardware. On the Poco X3 Pro, the most common are:

• 🔊 Failure of the conversational speaker – the membrane can be damaged, causing the sound to become louder and distorted.
• 📶 Poor contact plume speaker - leads to increased load on the amplifier.
• 🔋 Mikphone problems – if the person can’t hear you, the system automatically raises the volume.

For diagnosis:

1. Call another phone and check how you can be heard.
2. Connect headphones - if the volume in them is normal, the problem is in dynamics.
3. Record a voice message and listen to it – if the sound is distorted, repairs are required.

The cost of replacing the speaker on the Poco X3 Pro in service centers is 800-1500 rubles (2026).If the phone is warranty, contact the official Xiaomi service.
