How to add sound to the Xiaomi speaker: from simple settings to hidden features

Quiet sound on Xiaomi is a problem faced by owners of both budget Redmi and flagship Mi or POCO. The reasons can vary from the banal volume reduction in settings to hardware limitations of speakers. But in 80% of cases, the situation can be fixed without repair – just know where to dig.

In this article, we’ll look at all the ways you can turn up the volume, from standard regulators in the system to hidden options of the engineering menu and third-party utilities. Particular attention will be paid to models with stereo speakers (for example, Xiaomi 13 Pro or POCO F5), where the problem is often associated with an imbalance of sound between the top and bottom speakers. And if your smartphone is not the first year in use, then it may be the dust in the speaker grille, cleaning it sometimes gives +20% to the volume.

Before you start settings, check the obvious: Do Not Disturb or Meet Up profile is on the phone, which automatically reduces the volume of notifications and media. Also make sure that the player (like YouTube Music or Spotify) does not activate the volume limit - some apps have their own separate controls.

If the sound is gone completely (the speaker is not making any sounds), then the problem is probably hardware — the plume is damaged, the contact is broken or the amplifier is out of order. In this case, only the service center will help. But if there is a sound, but it is too quiet — read on.

1. Checking basic volume settings

Start with the simplest: check the current volume level in the system. Xiaomi has separate regulators for:

  • 🔔 Notifications (calls, SMS, signal)
  • 🎵 Media (music, video, games)
  • 📞 Calls (volume of conversational speaker)
  • 🔊 System sounds (keyboard, screen locking)

To open the volume control panel:

  1. Press the physical volume button up/down on the side panel of the smartphone.
  2. Touch the "cog" badge» (⚙️) slider-side.
  3. In the menu that appears, adjust each parameter separately.

And you can see the Media slider, which is the volume in most applications, and if it's at its maximum, but it's still quiet, you can move on to the next step.

📊 Which speaker is your Xiaomi quietest?
Upper (conversational)
Lower (multimedia)
Both equally quiet
I don't know.

An important nuance: some models (such as the Redmi Note 12 Pro+) have an Adaptive Sound feature that automatically lowers the volume in noisy areas.

  1. Go to Settings. → Sound and vibration.
  2. Find the Adaptive Sound option and deactivate it.

Activation of the "Sound amplifier" mode» (MIUI Sound Booster)

MIUI firmware (since version 12) has a hidden audio amplification feature that increases volume by 15-30% through software processing, activated via an engineering menu, but there is an easier way to do it through the developer settings.

Instructions for inclusion:

    Additional → For Developers

    Sound Booster

    ) and turn it on.

    Reboot your smartphone.

    When activated, the sound will become noticeably louder, but be careful: at maximum volume, distortion (wheezing) may appear at low frequencies. If this is critical, reduce the volume by 1-2 divisions from the maximum.

    ☑️ Preparation for sound amplification

    Done: 0 / 4

    ⚠️ Note: On models with Dolby Atmos (e.g. Xiaomi) 13T or POCO X5 Pro) Sound Amplifier may conflict with Dolby processing. If the sound gets worse after you turn on, turn off Dolby Atmos in the sound settings.

    3. Equalizer and Dolby Atmos setup

    If the sound is quiet only in certain applications (for example, YouTube or Spotify), the problem may be incorrect settings equalizer. MIUI has a built-in graphical equalizer that allows you to customize the sound to your preferences.

    How to set up the equalizer:

      The most frequent breakdowns:

      1. The plume of the speaker has gone away - after a fall or impact, the contact may be broken. Solved by soldering (repair cost: 1000-1500 rubles).
      2. The sound amplifier, the chip responsible for amplifying the signal, has failed. It requires replacement (price: 1500-3,000 rubles).
      3. The speaker membrane is damaged, for example, after moisture hits. The speaker is to be replaced (800-2000 rubles).

      To accurately diagnose the problem, perform a speaker test:

      1. Type the code on your phone keyboard: ##4636##.
      2. Select "Equipment Testing"** (Hardware Testing).

      💡

      If the phone is warranty, don’t try to fix the speaker yourself – this will void the warranty.

      FAQ: Frequent questions about Xiaomi sound

      🔊 Why my Xiaomi has a quiet sound in the calls, but normal in the music?
      This is because the speaker (top) is responsible for the calls, and the music is the multimedia (bottom). Possible causes: Clogged top speaker (cleaning will help). Failure of the speaker plume. Failure in the call volume settings (check in Settings → Sound → Call volume).
      🎵 Can I increase the volume on Xiaomi without root?
      Yes, most of the ways in this article don't require root rights: Equalizer settings and Dolby Atmos, Sound Amplifier enabled through the developer menu. Apps like Volume Booster GOODEV or Equalizer FX. Root will only be needed to install ViPER4Android or deep modification of system files.
      🔧 After updating MIUI It's quieter. What do you do?
      Updates sometimes reset the audio settings. Try: Reset Dolby Atmos settings (turn on/off function); update the app that has a quiet sound (like YouTube or Spotify); roll back to the previous version of MIUI (if the problem is massive, look for instructions on 4PDA or XDA forums).
      💦 The phone is wet and the sound is gone?
      If the phone has been in contact with water: Turn it off immediately and remove it. SIM-Put it in a bag of silica gel (or rice) for 24 to 48 hours. Don't turn it on until you make sure it's completely dry. If you don't have a sound after drying, contact the service (the speaker's contacts may have oxidized). Don't try to dry with a hair dryer, it will only accelerate corrosion!
      🔇 On mine. POCO X3 The sound is quiet only in games?
      In games, sound is regulated separately from system. Check: In-game audio settings (often there is a separate slider for music and effects). Is the MIUI not enabled with Game Acceleration mode** - it sometimes limits background processes, including sound. Update sound drivers through Settings → About Phone → Software Update.
