How to increase the volume of the speaker on Xiaomi Redmi 6A: from standard settings to hidden features

Xiaomi Redmi 6A is one of the most popular budget smartphones, but many users face the problem of quiet sound through the built-in speaker, especially when listening to music, watching videos or while making hands-free calls. In this article, we will explore all possible ways to increase the volume, from basic settings to advanced modifications that require caution.

It's important to understand that the volume limits on the Redmi 6A are not accidental, they're protection against sound distortion and damage to the speaker. However, if you're willing to compromise between quality and volume, you have a few options. We'll look at both safe methods (via Android settings and third-party apps) and risky ones (changing system files).

1. Checking basic sound settings

Before you resort to drastic measures, make sure that the problem is not the standard settings. The Redmi 6A has several options that can artificially limit the volume:

• 🔊 Do Not Disturb Mode: Check if it's activated in the audio settings. It can block notifications and turn down media volume.
• 🎵 Individual volume control: in MIUI The volume of the call, the media and the alarm are set separately.
• 🔄 Adaptive sound: function in the settings of Sound → Adaptive sound can automatically lower volume depending on the surrounding noise.

Also worth checking is the speaker's physical condition, a clogged grille or damaged membrane can significantly impair sound, carefully clean the speaker's opening with a soft brush (such as a toothbrush) and check the sound again.

⚠️ Warning: Do not use sharp objects to clean the speaker - this can damage the membrane.If after cleaning the sound does not improve, the problem may be in the hardware (detached contact or worn-out speaker).

2.Use of uniform sound distribution (EQ)

The MIUI on the Redmi 6A has a built-in equalizer that can improve the perception of volume by adjusting the frequencies. This will not increase the physical power of the speaker, but will make the sound more saturated:

1. Open the Music app (standard player from Xiaomi).
2. During playback of the track, tap the equalizer icon (three strips).
3. Choose a Basa or Rock preset – these amplify the low and medium frequencies, which subjectively makes the sound louder.
4. For fine tuning, go to Settings → Sound → Equalizer and manually lift the sliders to 100Hz and 1kHz.

If the standard equalizer seems weak, install a third-party app, such as Equalizer FX or Music Volume EQ. They offer more flexible settings and can sometimes increase volume by 10-15% through software processing.

3. Enabling the “Loud Communication” mode for media

The Redmi 6A has a hidden feature that allows you to redirect media (music, video) through the speakerphone, which can increase volume by 30-40%, but the sound quality will noticeably deteriorate:

1. Open any video in the standard Video or YouTube app.
2. During playback, pull the notification panel down.
3. Click on the speaker icon in the Quick Settings panel and select Loud Communication.

This method doesn’t work in all apps (for example, Spotify can ignore redirects). Also note that the speakerphone isn’t designed to play music for long periods of time – this can cause it to overheat.

💡

If the sound becomes hoarse or distorted, immediately return the mode to Dynamic. Long-term use of speakerphone for music reduces the life of the speaker.

Modification of system files (for experienced users only)

If standard methods fail, you can try changing the system files responsible for limiting volume. On Xiaomi Redmi 6A, this method requires unlocking the bootloader and root rights, which automatically deprives you of warranties and increases the risk of “bricking” the device.

The main file responsible for volume limits is called mixer_paths.xml. He's on the way. /system/vendor/etc/. For editing:

1. Get root rights (for example, through Magisk).
2. Install a file manager with root support (such as Root Explorer).
3. Find the file. mixer_paths.xml And back it up.
4. Open the file in the text editor and find rows with RX1 Digital Volume or Speaker Volume options.
5. Increase your max by 10-20 units (e.g., from 84 to 94).
6. Save the file, restart the device.

⚠️ Attention: Incorrect editing mixer_paths.xml If the phone stops turning on after the changes, you'll need to flash it over the Fastboot.

5.Use of the Engineering Menu (MTK Engineering Mode)

The Xiaomi Redmi 6A is built on a MediaTek Helio A22 processor, which gives you access to an engineering menu with advanced audio settings. This method does not require root, but you need to change the settings extremely carefully:

1. Open the Phone app and enter the code: ##36446337##
2. You will be taken to Engineering Mode. Go to Hardware Testing → Audio.
3. Select LoudSpeaker Mode (or Speaker).
4. In the Value field, increase the current value by 5-10 units (maximum 255, but it is not recommended to put above 160).
5. Press Set, then restart the phone.

The effect of this method is temporary - after resetting settings or updating the firmware values will reset, and some users also note the appearance of background or wheezing at maximum values.

6.Alternative methods: external speakers and Bluetooth devices

If all the software methods have failed, consider hardware solutions. Even budget external speakers or Bluetooth speakers sound louder and better than the built-in Redmi 6A speaker:

• 🎧 Bluetooth speakers: models like Xiaomi Mi Portable Bluetooth Speaker or JBL Go is inexpensive (from the 1500 rub) and give in 3-4 louder.
• 🔌 Wired earphones with external amplifier: some headphones (e.g. Sony) MDR-XB550AP) have a built-in amplifier that increases volume.
• 📱 FM-Transmitter: Devices like Baseus FM Transmitter allows you to broadcast sound from a smartphone to a car tape recorder or home acoustics.

If you want a compact option, look for overhead speakers (such as the Xiaomi Mi Pocket Speaker 2) that attach to the back of the phone and use it as a resonator, amplifying the sound without wire connection.

7.When to contact the service center

If none of the methods worked, the problem may be a hardware malfunction.

• 🔇 The speaker is not working at all (no sound even at maximum volume).
• 🔊 The sound is distorted, wheezing or crackling can be heard at any volume.
• 🔋 The phone overheats when playing sound through the speaker.
• 💧 On the speaker visible traces of corrosion or mechanical damage.

The cost of replacing the speaker with Redmi 6A in official Xiaomi services is about 800-1200 rubles (2026). Unofficial workshops can offer cheaper, but the risk of installing non-original spare parts is higher.

Before visiting the service, make a backup copy of the data - during the repair, you may need to reset the settings.
