How to increase the volume of the speaker on Xiaomi smartphones: from software settings to repair

Did you notice that while calling the interlocutor is not audible, although music and video play normally? The problem with low volume of the conversational speaker is one of the most common in Xiaomi smartphones, especially after updates or prolonged use. Unlike multimedia speakers, the conversational speaker (also known as the top speaker or earpiece) is responsible only for the voice of the interlocutor, and its settings are often hidden from the user.

In this article, we will discuss 7 working ways to increase volume, from basic MIUI/HyperOS settings to engineering menus and hardware solutions. It is important to understand that if the problem is caused by a physical breakdown (for example, moisture or membrane wear), software methods will not help. But in 80% of cases, the volume can be increased without repair. Next, step-by-step instructions based on the features of Xiaomi firmware from 2020-2026.

1. Checking basic volume settings

Before you dig deeper, make sure that the problem is not the trivial settings. On Xiaomi smartphones, the volume of the speaker is adjusted separately from the multimedia sound.

• 🔊 Loudness during the call: during the conversation, press the volume buttons - a window with a slider "Loudness of the call" should appear on the screen.
• 📞 Phone mode: If you use a headset or Bluetooth headphones, the sound can automatically switch to them. Turn off all accessories and check the volume directly.
• 🚫 Inactive microphone: sometimes the person is not heard because of a problem with your microphone, not the speaker.

If the volume slider is already at its maximum, but the sound is still quiet, move to the next section. Some models (such as the Redmi Note 10 Pro or the POCO X3 Pro) reset their individual EQ settings after upgrading to HyperOS, which are also worth checking.

⚠️ Note: On smartphones with stereo speakers (for example, Xiaomi 12 Pro or Redmi) K50) You can duplicate the spoken sound on the bottom speaker, if it's dirty, the overall volume drops.

2. Equalizer and sound effects setup

MIUI and HyperOS offer built-in tools for fine-tuning the sound, but they are often ignored by users, and these settings affect the speaker speaker, albeit indirectly. Here's how to optimize them:

1. Go to Settings → Sound and vibration → Sound quality.
2. Turn on Adaptive sound (if any) – it automatically adjusts the volume to the surrounding noise.
3. Choose a Preset equalizer Voice or Speech (some models call it Conversation). If there are no Presets, create a customized one with elevated average frequencies (1-4 kHz).
4. Turn off ambient sound effects (such as 3D Audio or Dolby Atmos) – they can suppress voice frequencies.

On HyperOS smartphones (such as Xiaomi 14 or Redmi Note 13), the path to the equalizer may be different: Settings → Sound → Sound effects. If there is no audio quality option at all, then your model does not support the software processing of the conversational speaker - go to the engineering menu.

3. Engineering menu: hidden volume settings

If standard methods don't work, you should check the Engineering Mode, where you can manually increase the volume of the speaker to bypass the firmware constraints, and be careful: the wrong settings can cause the sound to be distorted or the speaker to be damaged!

Instructions for Xiaomi:

1. Open the Phone app and enter the code: ##36446337## Some models (e.g. POCO) may have an alternative code: #4636###
2. Go to Hardware Testing → Audio → LoudSpeaker Mode (or Receiver).
3. Find the settings: Max Vol (maximum volume) – increase the value by 5-10 units (for example, from 160 to 170). Type – select Sph (for a conversational speaker). Level – set to 6 or 7 (maximum).

Save the settings and restart the phone.

If the sound is distorted or wheezing after the changes, return the values to their place. On HyperOS models (such as Xiaomi 14 Ultra), the engineering menu can be blocked, in which case only root or third-party software will help.

⚠️ Note: On smartphones with Qualcomm processors (for example, Redmi Note 12 Pro)+) Changing the Max Vol above 180 can overheat the speaker. Optimal range is 160-175.

Record the current parameters |Do not exceed Max Vol >180| Check the sound after each change |Reset the settings for distortions-->

Cleaning of the speaker and checking for physical damage

Often, the silent sound is not caused by settings, but by the contamination of the speaker, and the dust, hair, or moisture can block the membrane, lowering the volume.

• 🧹 Soft brush: use a paint brush or a soft bristle toothbrush. Carefully run the speaker along the grille without pressing.
• 💨 Compressed air cylinder: spray in short bursts (hold the balloon vertically to avoid liquid intrusion).
• 🧲 Magnetic case: If you use magnet cases, check if they cover the speaker. On some models (for example, Xiaomi 13 Lite), the magnetic field can affect the sound quality.

If the sound has not improved after cleaning, check the speaker for physical damage:

1. Illuminate the speaker with a flashlight into the grille - the membrane should be whole, without tears.
2. Blow into the speaker (carefully!): If a crunch or uneven sound is heard, the membrane is damaged.
3. Check if the back cover is swollen near the speaker - this is a sign of moisture getting in.

If damage is detected, the speaker must be replaced. The cost of repair in the service center Xiaomi — from 800 to 2500 rubles depending on the model. on Redmi cheaper, on flagships (for example, Xiaomi 13T Pro) — more expensive.

5. Third-party applications for sound amplification

If the engineering menu is unavailable or the changes have not worked, you can use third-party utilities that run on top of the system settings and can increase volume through software processing.

• 🔊 Volume Booster (from Google Play): allows you to increase volume by 20-30% by changing system limits.
• 🎛️ Equalizer FX: Advanced equalizer with pre-settings for voice. It works even on HyperOS.
• 🛠️ SoundAssistant (from Samsung, but compatible with Xiaomi): allows you to divide the volume for different types of sound (calls, multimedia, alarm clock).

Installation and configuration:

1. Download the app from the official store (avoid APK from third-party sources!).
2. Run and provide all the permissions you have requested (especially access to the Sound Settings).
3. In Volume Booster, select Call Volume and move the slider 110-120%.
4. In Equalizer FX, activate the Voice Boost preset or create your own with 2–5 dB gain in the 1–4 kHz range.

The downside of these applications is that they consume an extra battery and may conflict with system updates. After installing HyperOS, some utilities stop working, in which case you will have to look for alternatives or go back to the engineering menu.

💡

Before using volume boosters, check if the settings include Power Saving Mode, which limits the processor's performance, which can affect the processing of sound.

6. Update firmware and reset settings

Sometimes the volume problem is caused by firmware bugs, especially after major updates (for example, switching from MIUI 13 to HyperOS).

• 🔄 Update to the latest version of the software: go to Settings → The phone. → Update the system and check for updates.
• 📲 Resetting sound settings: in Settings → Annexes → Application management find sound settings, clear cache and data.
• ⚙️ Last resort: If nothing helps, back up and reset to factory settings (Settings) → Additionally. → Recovery and discharge).

On HyperOS models (such as Xiaomi 14 or Redmi Note 13 Pro+), the sound policy may reset after the update.

1. Go to Settings → Special features → Improve the sound.
2. Enable the voice amplification option (if any).
3. Turn off Automatic Volume Control – it can lower the sound level in noisy conditions.

If the speaker is quieter after the update, check the update logs on Xiaomi's official website. Sometimes newer versions of the firmware artificially lower the volume to meet European standards (for example, in models for the EU market).

💡

Before resetting the settings, write down the current values of the equalizer and the engineering menu - after resetting, they will have to be adjusted again.

7 Hardware solutions: replacement of speaker or amplifier

If all software methods have been tried and the sound is still quiet, the problem is probably hardware.

• Speaker (top) – most often fails due to moisture or mechanical damage.
• Audio codec is the circuit on the motherboard, which is responsible for processing sound, and when it breaks, the sound can disappear completely or become distorted.
• A sound amplifier is a separate chip that amplifies the signal before output to the speaker. On cheap models (for example, the Redmi 9A) often save on the amplifier, which leads to low volume.

How to diagnose:

Cost of repair:

• Replacement of a conversational speaker: 800-2500 rubles (depending on the model).
• Repair/replacement of the audio codec: 3000-6000 rubles (requires soldering).
• Diagnosis at the service center: free (if you repair them).

If your Xiaomi is still under warranty, don’t disassemble it yourself – this will void the warranty. Contact the official service center with a check. For models older than 2 years (for example, the Redmi Note 9 Pro 2020), repairs can cost more than buying a new phone.
