How to set up a speaker on Xiaomi Redmi phone: from balance to equalizer

Speakers in Xiaomi Redmi smartphones often become a source of frustration: the sound is too quiet in the speakers, the bass wheezes at maximum volume, the voice of the interlocutor during the call is barely audible. The reasons can lie in hardware constraints (for example, the Redmi 9A or Redmi Note 10 models have only one speaker), and incorrect software settings. In this article, we will analyze all ways to optimize the sound from basic volume parameters to hidden MIUI functions, which the manufacturer does not advertise.

It’s important to understand that the speaker setup depends on the firmware version (MIUI 12, 13 or 14) and the specific smartphone model. For example, the flagship Redmi K50 and Redmi Note 12 Pro+ are equipped with stereo speakers with support for Dolby Atmos, while budget devices like the Redmi A1 lack even a basic equalizer. We will look at universal solutions, and also point out features for different lines.

If you've had all the manipulations, the sound is still poor, and the problem can be hardware, from a clogged speaker to a broken plume, and you'll need a diagnostic at a service center, but 80 percent of the time, the right setup helps.

Basic volume and sound settings

Start by checking the obvious parameters. Xiaomi Redmi adjusts volume separately for multimedia, calls and alarms. Often users complain about the quiet sound in games or videos, not knowing that they simply did not turn up the volume for the corresponding profile.

How to check:

• 🔊 Press the physical volume button on the side panel of the smartphone. a slider will appear with a choice of mode: Multimedia, Call, Alarm or Notifications.
• 🎵 Make sure that the top notification bar does not activate the Do Not Disturb mode (the bell icon with cross-out).
• 📱 Go to Settings. → Sound and vibration → Volume and manually adjust levels for each type of notification.

Pay special attention to adaptive sound settings, and some models (like the Redmi Note 11 Pro) have Adaptive Sound, which automatically adjusts the volume to suit the noise level in the room, to enable this:

1. Open Settings → Special features → Hearing → Adaptive sound.
2. Activate the switch and adjust the microphone sensitivity.

⚠️ Attention: Redmi with MIUI 14 The path to adaptive sound may be different: Settings → Additionally. → Hearing aids. If you don't have an option, your model doesn't support it.

Equalizer and sound effects setting

The equalizer allows you to fine-tune the sound to your preferences: strengthen bass for music, improve the legibility of voice in podcasts or smooth out high-frequency peaks. At Xiaomi Redmi, access to the equalizer depends on the firmware version and model:

For devices with MIUI 12/13:

1. Open the Music app (standard player from Xiaomi).
2. During the playback of the track, tap the icon ⚙️ Settings → equalizer.
3. Choose one of the preset profiles (Rock, Pop, Jazz) or create your own by moving the frequency sliders.

For MIUI 14 and newer models (e.g. Redmi Note 12):

• 🎧 Equalizer moved to Settings → Sound and vibration → Sound quality → equalizer.
• 🔄 It also has Dolby Atmos (if supported by hardware) and activate it for surround sound in headphones or speakers.

If there is no standard equalizer, install a third-party app like Equalizer FX or Wavelet, which offers more presets and supports system integration.

⚠️ Note: On a Redmi with a single speaker (e.g. Redmi) A1) Turning on Dolby Atmos may make the sound worse by trying to simulate the stereo effect.

Make sure that the volume of multimedia is at maximum

Turn off Do Not Disturb mode.

Check for an equalizer in the player

Diagnostics of hardware problems with speakers

If after all the settings, the sound remains quiet, hoarse or disappears altogether, the cause may lie in a hardware malfunction.

Test speakers through the engineering menu:

1. Open the phone app and enter the code: ##4636##
2. Select the item Phone Information → Test menu (on some models the path may be different).
3. Slip on Audio → Speaker Test and listen to the test signals.

Signs of hardware problems:

• 🔇 One of the speakers (top or bottom) does not make sound at all.
• 🎶 The sound is distorted at high volume (wheezing, crackling).
• 💧 After getting moisture, the speaker began to "bumble" or sound muffled.

If the test confirms a malfunction, try to clean the speaker of dust with a soft brush or compressed air. Never use sharp objects - this can damage the speaker membrane. If the problem persists, contact the service center. The cost of replacing the speaker with a Redmi varies from 800 to 2500 rubles depending on the model.

Customization of sound for calls and microphone

Sound problems during calls are a separate headache for Xiaomi Redmi owners, and users often face two situations:

1. The interviewer can't hear you - a microphone problem.
2. You can’t hear the speaker, you have a problem with the top speaker.

Solution for microphone:

• 🎤 Check if you cover the microphone with your finger or cover while you ring.
• 🔧 Clean the microphone hole (usually located at the bottom of the case) of dust.
• 📞 When you call, turn on speakerphone and see if your hearing has improved.

Solution for a conversational speaker:

1. Open Settings → Apps → Phone → Permissions and make sure the app has access to the microphone and speakers.
2. Reset network settings: Settings → SIM-maps and mobile networks → Resetting network settings.
3. If the sound is only lost in headphones, try to clear the Type-C connector or 3.5 mm (if any) of oxidation.

Some models, like the Redmi Note 11, have a hidden voice amplification option to activate it:

Settings → Special features → Hearing → Sound amplification when calling

Optimizing Sound for Games and Video

Gamers and video enthusiasts often experience audio lag or low volume in games, and Xiaomi Redmi addresses this in the following ways:

To eliminate the sound delay:

• 🎮 Turn on Game Mode: Swipe down from the top edge of the screen → Take a look at the Game Turbo icon.
• 🔊 In the game settings (cog in the upper right corner) select Optimize the sound.
• 📱 Disable all background applications that consume CPU resources (especially relevant for Redmi 9 with Helio) G80).

To increase the volume in games:

1. Install the Volume Booster app (ADB rights are required to unlock restrictions).
2. Turn on Dolby Atmos in the sound settings and select the Game profile.
3. Use Bluetooth headphones with aptX Low Latency support to minimize latency.

The Redmi K50 Gaming Edition and other gaming models have additional audio settings in the Game Turbo:

• 🎧 3D-sound for headphones - creates the effect of surround sound.
• 🔇 Turn off the notification sound so you don’t get distracted during the game.

💡

If the game is interrupted, try turning off the energy-saving mode in the battery settings. Xiaomi aggressively restricts background processes, which can affect audio playback.

Resetting sound settings to factory

If after all the manipulations, the sound has only gotten worse or there are distortions, return the settings to the factory settings, which will help to eliminate software failures.

How to reset the sound settings:

1. Open Settings → System → Resetting settings.
2. Select Resetting Sound Settings (not to be confused with a full reset!).
3. Confirm the action and restart the smartphone.

If there is no audio reset option, perform a full reset (Recover and Reset → Reset) but pre-reverse the data.

What to do after the discharge:

• 🔄 Update your firmware to the latest version through Settings → The phone. → Updating the system.
• 🎵 Reconfigure the equalizer and Dolby Atmos.
• 📲 Reinstall applications related to sound (players, instant messengers).

⚠️ Note: On Redmi with custom firmware (like LineageOS), resetting audio settings can result in loss of features like Dolby Atmos.

💡

Resetting audio settings is the last step before you go to the service, and 60 percent of the time, it solves the problem of distorted or lost sound.

Additional Tips for Improved Sound

A few non-obvious tricks that will help you to squeeze the most out of the Xiaomi Redmi speakers:

For owners of stereo speakers:

• 🔀 Turn on the dual speaker in the audio settings (available on the Redmi Note 10 Pro and later).This uses both speakers to play music, not just the bottom one.
• 🎬 When watching a YouTube or Netflix video, turn the screen horizontally and the sound will become louder due to the redistribution of the load.

For owners of models with one speaker:

• 📦 Use a box or glass as a resonator: Put your phone in an empty box with the screen upwards, the sound will become louder due to the reflection.
• 🔊 Install Samsung’s SoundAssistant app (which works on Xiaomi too), which allows you to divide the volume for each app and adds a quick control widget.

For all models:

• 🔋 Watch the battery level.At below 15%, Xiaomi automatically lowers the volume to save energy.
• 🌡️ Do not use your phone in extreme temperatures (below 0)°C or higher than 40°C) – this degrades sound quality due to changes in speaker properties.
