How to set up a speaker on a Xiaomi phone: from bass to call volume

The sound quality on Xiaomi smartphones is often a subject of controversy: some users praise loud speakers on flagships like Xiaomi 14 Ultra, others complain about the quiet sound in budget models like Redmi Note 12. The reason is not always in the “hardware” – often the problem lies in the wrong settings MIUI, which are optimized by default for the “average” user. Meanwhile, even in standard tools of the system, features are hidden for fine-tuning the sound: from equalizer correction to separate media volume adjustment and notifications.

In this article, we will discuss all the ways to improve the sound of speakers on Xiaomi, Redmi and POCO phones, from basic settings to hidden “chips” MIUI 14/15. Focus on practical solutions: how to amplify the bass, why the sound was lost in the dynamics, how to make calls louder and what to do if the speaker wheezes. Instructions will be suitable for most models released after 2020 (including Xiaomi 13T, Redmi Note 13 Pro+ and POCO F5).

⚠️ Important: Sound settings may vary depending on the version MIUI If you don't have any of the items on your menu, check for system updates in Settings. → The phone. → Updating the system.

1. Basic volume settings: what can be changed without root

The first thing to start with is the standard volume controls in MIUI, which many users don't know is that there's a separate setup for different types of sounds: media, calls, alarms and notifications, which allows you to make music louder without affecting the volume of the call, for example.

To open the extended settings:

1. Press the physical volume button (up/down) on the sidebar of the phone.
2. Touch the "cog" badge» (⚙️) upper right corner of the pop-up window.
3. Move the sliders for each type of sound separately: 🎵 Multimedia – the volume of music, video, games. 📞 Call – the volume of incoming calls. ⏰ Alarm clock – the volume of the alarm signal. 🔔 Notifications - sounds SMS, push-message.

⚠️ Warning: If the sound starts to distort after the change of settings (wheezing, crackling), then the speaker is working at the power limit. In this case, reduce the volume by 10-15% or check the speaker for physical damage (see section 5).

Equator and Sound Effects: How to Improve Bass and Sound Purity

MIUI offers a built-in equalizer that allows you to customize the frequency response of the sound to your preferences, which is especially useful if you lack bass or, conversely, high frequencies.

Settings → Sound and vibration → Equator

The equalizer menu is available:

• 🎛️ Presets ("Rock", "Pop", "Classic" and others) - a quick choice for the genre of music.
• 📊 Manual tuning – adjusting sliders for 5-7 frequency ranges (60 Hz to 16 kHz).
• 🔊 Bass amplifier - a separate regulator for low frequencies (available on all models).
• 🎧 Effects for headphones – turn on automatically when wired/wireless headphones are connected.

On models with stereo speakers (such as the Xiaomi 13 Pro or POCO F4 GT), the equalizer works separately for each speaker, which allows you to create a surround sound effect. If your phone supports Dolby Atmos or Hi-Res Audio, these options will appear in the same menu.

Select the preset "Bases" or "Electronics"

Increase sliders by 60-250 Hz (low frequencies)

Reduce sliders by 4–8 kHz (to avoid distortion)

Turn on the Bass Amplifier (if available on the menu)-->

3. speaker problems: why the sound is quiet or wheezing

If your Xiaomi speaker is quieter, wheezing or not working at all, the reasons may be both software and hardware.

🔧 The first thing to do when you have a sound problem:

1. Reboot your phone – it will reset the temporary errors of the sound driver.
2. Check if the sound is blocked by a cover or protective film (especially for models with a lower speaker, for example, the Redmi Note 10 Pro).
3. Update the firmware – newer versions of MIUI often fix sound bugs.

4. Hidden sound settings: engineering menu and ADB-team

For experienced users who are ready to dive into technical details, MIUI offers advanced options through the Engineering Menu and ADB.

• 🔊 Change the volume limit (remove the limit) EU-version).
• 🎚️ Set up a balance between speakers (on models with stereo sound).
• 🔧 Enable debugging of the sound driver.

⚠️ Note: Incorrect use of the engineering menu or ADB This can cause phone malfunctions. Backup data before changes!

🔹 How to Open an Engineering Menu:

1. Open the Phone app.


2 Enter the code: ##3644633## (for MTK) or ##4636## (universal).




3. Go to the Hardware Testing section → Audio.




4 Every speaker, microphone and headphones can be tested here.

🔹 ADB-commands to remove volume limit (requires PC):

adb shell settings put global volume_steps 30 # Increases the number of volume steps


adb shell settings put global volume_music_steps 30




adb shell settings put global volume_voice_steps 15

💡

If after changes in the engineering menu, the sound is completely lost, reset the sound settings to Settings → System → Resetting → Reset the sound settings.

5.Sound Improvement Apps: What Works for Xiaomi

If standard MIUI tools are not enough, you can use third-party applications, the main thing is to choose those that are compatible with Xiaomi firmware and do not conflict with system services.

• 🎵 Equalizer FX — Advanced equalizer with presets and manual correction.Works on most Xiaomi models without root.
• 🔊 Volume Booster – Increases volume through software processing (caution: may cause distortions!).
• 🎧 Wavelet – an application with support LDAC and aptX, optimizes sound for headphones and speakers.
• 🔧 SoundAssistant (from Samsung, but runs on Xiaomi) – allows you to adjust a separate volume for each application.

⚠️ Attention: Apps to amplify sound can damage speakers if used at maximum volume for a long time.

📌 How to install:

1. Download APK from the developer’s official website (e.g. Equalizer FX).
2. Allow installation from unknown sources in Settings → Applications → Special Rights → Installation of unknown applications.
3. After installation, open the application and give access to the sound system.

💡

Third-party equalizers only work with multimedia (music, video), they do not affect the volume of calls and notifications - use the standard MIUI settings for this.

6.Tune the sound for calls and notifications

The story is the sound of calls and notifications, and many Xiaomi users complain that even at maximum volume, they miss calls.

🔹 Change the ringing melody:

• Go to Settings → Sound and vibration → Call melody.
• Choose a tune with a wider frequency range (e.g., the standard “Call 1” or “Call 2” in MIUI is usually louder than the user’s).

🔹 Enable call amplification:

• Activate the option Settings → Special features → Sound amplification.
• Turn on “Call Volume Up” – this will temporarily disable restrictions when an incoming call is made.

🔹 Set up the vibration:

• If the sound is still hard to hear, add vibration to Settings → Sound and vibration → Vibration when ringing.
• For notifications, set up a separate vibration rhythm in Settings → Notifications → Notification settings.

💡 Tip: If you miss calls frequently in noisy places, install the Loud Alarm app from Google Play, which ignores system limitations and can increase the volume of a call to the maximum, even if the settings are average.
