How to reduce the volume of the speaker while talking on Xiaomi Redmi Note: 5 proven ways

Are you tired of being overly loud when you're talking on a phone, even when the volume control is turned to a minimum? This is a problem that many Xiaomi Redmi Note owners -- especially the Redmi Note 10/11/12 and its variants -- are familiar with, because the manufacturer often overstates the factory volume settings of the speaker to compensate for external noises. But in a quiet environment, it can cause discomfort or even cut the ear.

In this article, we'll look at all the ways you can reduce the volume of your speaker when you talk, from the standard MIUI settings to the hidden parameters of the engineering menu, how to adjust the sound without root rights, what apps can help you tune the audio more accurately, and what to do if the problem lies in the hardware of the phone, and we'll also explain why sometimes the volume itself "jumps" during a call and how to fix it.

Why is the speaker on Xiaomi Redmi Note too loud?

Before you start settings, it is important to understand the reasons for excessive volume. In smartphones Xiaomi Redmi Note (especially in the lines Note 8/9/10/11/12) often occur the following β€œbugs” and features:

  • πŸ”Š Factory firmware MIUI It artificially overstates the volume of the speaker to make it easier to hear in noisy conditions. It's a marketing ploy, but it's not always appropriate.
  • πŸ“± Hardware limitations: in some models (e.g. Redmi Note 8 Pro or Note) 10S) It uses a high-sensitivity speaker that physically reproduces sound louder.
  • πŸ”„ Automatic volume control (Adaptive Sound function in the MIUI) It can disrupt settings during a call if the phone thinks you are in a noisy place.
  • πŸ› οΈ Software failures after firmware updates - especially relevant for devices updated to MIUI 13/14 or hyperos.

Fun fact: some regional firmware versions (like India or China) have a higher volume than global builds, which is due to local communication standards and noise levels, and if you bought a Redmi Note in the gray way, chances are it's not your firmware.

Method 1: Standard MIUI settings

To start with, the basics are built-in MIUI tools, and many people don't know that Xiaomi smartphones have separate volume controls for media, alarm clocks and conversational speakers, and here's how to use them:

  1. When you call, press the physical up/down volume buttons on the side panel of the phone. A slider will appear on the screen that says "Call Volume - Adjust it."
  2. If the buttons don’t work during the conversation, tap the speaker icon on the call screen – the same regulator will open.
  3. After the call is completed, the settings will remain and will apply to the next calls.

But there's a limitation to this method: the minimum volume in MIUI is often too high. If the 0 is loud, move on to the following.

πŸ’‘

If the volume β€œjumps” again during a conversation after adjusting, turn off the Adaptive Sound function in the settings: Settings β†’ Sound and vibration β†’ Adaptive Sound.

Method 2: Engineering menu (without root)

To fine-tune the volume of the speaker, you can use the Engineering Mode, a method that requires no super-user rights and works on most Redmi Note models. It's important: don't change the other options in the engineering menu unless you know what they're going to do!

Instructions:

  1. Open the Phone app and type the combination: ##4636## Some firmware may require you to type: ##36446337###
  2. Select Hardware Testing (or Audio Tests in Russian firmware).
  3. Go to Audio β†’ LoudSpeaker Mode (or hands-free mode).
  4. Find Sph (microphone) and Sph2 (talk speaker). For Sph2, set Level in the range of 0-5 (usually 6-7 by default).
  5. Save the changes and restart the phone.

Note: Some models (e.g. Redmi Note 12 Pro+ 5G) may have the engineering menu locked, in which case use method 3 or 4.

Method 3: Applications for volume control

If the standard methods didn't work, third-party utilities will come to the rescue, and we tested several applications and selected those that work well on MIUI and do not require root rights:

  • πŸ”§ Volume Booster & Equalizer (by Smart Android Apps) – allows you to reduce the volume of the speaker to the same level. 20% It's standard, supports Redmi Note. 10/11/12.
  • πŸŽ›οΈ Precision Volume is a precise volume setting with 1% increments. There is a separate slider for Call Volume).
  • πŸ“± SoundAssistant (from Samsung, but runs on Xiaomi) – has a Separate App Volumes feature that allows you to adjust the volume for phone calls separately.

How to use:

  1. Install one of the apps (links are available in Google Play).
  2. Launch and grant permissions to access the audio settings.
  3. Find the Call Volume or Loudness section.
  4. Reduce the slider to a comfortable level (we recommend starting with 50-60% of the standard).

⚠️ Note: Some applications (such as Volume Booster) may conflict with MIUI and reset the settings after rebooting. To avoid this, add the app to Autorun via Settings. β†’ Annexes β†’ Permits β†’ Auto-start.

What to do if the application does not work?
If the volume is unchanged after installing the utility, check: 1. Have you allowed access to the Sound Settings (manually in Android settings). 2. Does MIUI block the application through Battery Optimization (turn off Utility Optimization). 3. Is the application compatible with your version of MIUI (some utilities do not work on HyperOS).

Method 4: Change firmware files (for advanced)

If you're ready for more radical measures, you can edit the system files that control volume, which requires an unlocked bootloader and access to the file system through ADB or Root Explorer, and we'll look at the safest option, through ADB without full root.

Instructions:

  1. Install ADB and Fastboot Tools on PC.
  2. Turn on USB Debugging on your phone: Settings β†’ About Phone β†’ MIUI Version (click 7 times to become a developer) β†’ Settings β†’ Additional β†’ Developers β†’ Debugging on USB.
  3. Connect your phone to your PC and execute the command: adb shell settings put global volume_call 3 where 3 β€” desired volume level (range of the range from 0 before 7).
  4. Reset the device.

This method changes the system parameter, but does not affect the firmware files directly, so the risk of β€œbricking” is minimal. ADB.

πŸ’‘

Changing system settings through ADB is the only way to reduce the volume below factory minimum without root, but after resetting the settings or updating the firmware, the parameters will reset.

Method 5: Hardware solutions (if nothing helps)

If the software methods fail, the problem may lie in the hardware of the phone, and here are the most common causes and ways to fix them:

  • πŸ”Š Contamination speaker: Dust or moisture can change the acoustic properties of the membrane, making the sound louder and more distorted. The solution is to clean the speaker carefully with a soft brush or compressed air.
  • πŸ“± Speaker plume damage: If the phone fell or disassembled, the contacts could oxidize.
  • πŸ”‹ Audio codec malfunction: The chip that handles the sound may fail.

How to check if there is a hardware problem:

  1. Put your headphones on and check the volume of the sound while you're talking. If the headphones are normal, the problem is the dynamics.
  2. Record your voice on a tape recorder and compare it to how people hear you, and if your voice is quiet and people complain about the volume, it's the microphone or the audio codec.

⚠️ Warning: Don't try to disassemble the phone yourself if you don't have experience! In Redmi Note models, the speaker is soldered to the motherboard, and careless actions can lead to complete failure of sound.

Frequent Mistakes and How to Avoid Them

When trying to reduce the volume of the speaker, users often make mistakes that only exacerbate the problem, and here are the most common ones:

  • πŸ”‡ Disable all sounds in settings: Some users are desperate to turn off Media and Notifications in Settings β†’ Sound, but it doesn't affect the volume of the speaker.
  • πŸ”„ Resetting to factory settings: It won't solve the problem, it will only delete all your data.
  • πŸ“± Use of "repair" firmware: Unofficial firmware may contain viruses or unstable sound drivers. Install only official updates through Settings β†’ Updating the system.

Another common mistake is ignoring firmware updates. Newer versions of MIUI often fix sound bugs. For example, MIUI 14.0.4 for Redmi Note 11 fixed a bug that spontaneously increased volume during a call.

  1. Go to Settings β†’ About the phone β†’ System update.
  2. Click Check for updates.
  3. If a new version is available, install it.

FAQ: Answers to Frequent Questions

Can you reduce the volume of the speaker on Xiaomi Redmi Note without root?
Yes, most of the methods in this article (standard settings, engineering menus, third-party apps) do not require root rights. Only editing system files through ADB or Root Explorer will require unlocking the bootloader.
Why is the volume back to maximum after the MIUI update?
Firmware updates reset some user settings, including the engineering menu and ADB. After the update, you will have to re-apply the changes. To avoid this, use third-party applications (such as Precision Volume), which save the settings regardless of the updates.
Will Xiaomi’s warranty work if I change the settings through the engineering menu?
Yes, the warranty is maintained if you have not physically damaged your phone, the Engineering Menu is a standard diagnostic tool and its use is not considered hacking, however, if you change other settings (for example, those associated with RF modules), this can result in the warranty being voided.
Can you adjust the volume separately for each contact?
In standard MIUI settings, this feature is not available, but you can use the SoundAssistant app (see Method 3), which allows you to assign individual volume profiles to different contacts through the Per-App Volume function.
What if after all the manipulations the speaker is still too loud?
If the software methods didn’t work, there are two options: Contact Xiaomi’s service center for hardware diagnostics (possibly a faulty audio codec or speaker); Using a Bluetooth headset for calls completely bypasses the phone’s conversational speaker.
