Why Xiaomi’s speaker is quiet and how to fix it: The Complete Guide

If the speaker on your Xiaomi smartphone is quieter than usual, it can seriously spoil the impression of using the device. The problem manifests itself in different ways: sometimes the sound is barely heard during calls, in other cases the bass range disappears when listening to music, and sometimes one of the speakers stops working. The reasons for this behavior can be both software (incorrect settings, software failures) and hardware (pollution, damage to the membrane or contacts).

In this article, we will look at all the possible ways to diagnose and fix a problem, from basic checks to complex technical manipulations. It is important to understand that some methods require caution, especially when it comes to disassembling a device or changing system files. We will also tell you when to contact a service center and when you can manage yourself.

1. Checking basic sound settings

Before you sin on hardware malfunctions, make sure that the problem is not in the settings of the system. Xiaomi often updates the MIUI firmware, and sometimes after updates, the sound parameters are lost.

• 🔊 Media and call volume: Press the physical volume button and make sure the slider is not in the minimum position. MIUI There are separate regulators for multimedia, calls and alarms.
• 🎵 Do Not Disturb Mode: Go to Settings → Sound and vibration → Don't disturb and turn off this mode if it's active. Sometimes it blocks notifications and lowers the volume.
• 🔕 Sound Profile: In the same audio settings, check if you have a Quiet or Vibration profile".
• 📱 Adaptive sound: In some models (Xiaomi) 12/13 series, Redmi Note 11/12) You have a function to adapt the sound to the environment. → Special facilities → Adaptive sound.

If you don't recover sound after this manipulation, then move on to the next step. It's also worth noting that some devices (like the POCO F4/F5) have a separate setting for the balance of sound between the left and right speakers - check it in the Settings → Sound → Stereo balance menu.

Cleaning of speakers from dust and debris

One of the most common causes of silent sound is speaker pollution, and dust, pocket pile, or small debris can block the membrane, making the sound muted or distorted, especially for devices without IP68 certification (such as the Redmi 9/10 series or the POCO M4/M5).

How to Clean Your Spells Safely:

• 🧹 Soft brush: Use a brush with soft pile (like makeup) or a toothbrush with cropped bristles. gently swipe the speaker along the grille without pressing hard.
• 💨 Compressed air cylinder: If you have access to such a cylinder (sold in electronics stores), blow through the speaker holes in short pulses. Keep the balloon vertically to avoid liquid ingress.
• 🧲 Scotch or sticky tape: Cut a small piece of tape, fold it with the sticky side outside and gently press the speaker against the grille.

⚠️ Warning: Do not use sharp objects (needles, toothpicks) under any circumstances - they can damage the speaker membrane. Also avoid wet wipes or alcohol: liquid can leak inside and cause corrosion of contacts.

If the sound has improved after cleaning but has not fully recovered, the problem may be membrane damage or contact detachment, which requires disassembling the device or contacting the service.

3. Diagnostics of program failures

MIUI malfunctions or application conflicts can cause the sound system to malfunction, for example, after a firmware update, some users of the Xiaomi 11T and Redmi Note 10 Pro complained of a sharp decrease in volume.

• 🔄 Reboot device: Sometimes a banal reboot helps to reset the temporary errors of the sound driver. Press the power button and select "Reboot".
• 🛠️ Resetting sound settings: Go to Settings → System system → Resetting settings → Reset the sound settings, and that brings all volume and equalizer back to the factory.
• 📱 Safe Mode: Press the power button, then hold your finger on "Stop" until "Safe Mode" appears. This mode only runs system applications. If the sound is normalized, one of the installed applications is to blame.
• 🔍 Permissions Checker: Some applications (e.g. Equalizer) FX or ViPER4Android) They may conflict with the built-in sound stack. → Annexes → Manage applications and check permissions for sound utilities.

If the problem only manifests itself in certain apps (like YouTube or Spotify), try:

1. Clear the app cache in Settings → Apps → [App name] → Storage → Clear the cache.
2. Update the app to the latest version on Google Play.
3. Remove and install the application again.

4. Update firmware and reset to factory settings

If the silent sound came after the MIUI update, there may be a bug in the firmware. Xiaomi regularly releases patches to correct such errors.

1. Check the current firmware version in Settings → About Phone → MIUI version.
2. Update: Settings → About Phone → System Update. If you have an update, install it.
3. If there are no updates, but the problem remains, try to roll back to the old version (if you know that the sound worked normally before).

If the update didn't work, the last software method is to reset completely, and that will delete all the data from the device, so back up first.

1. Go to Settings → About Phone → Backup and Reset → Reset settings.
2. Select “Erase all data” and confirm the action.
3. After the reboot, set the phone as new and check the sound.

⚠️ Warning: Resetting to factory settings deletes all data, including photos, contacts and messages. If you don't have your Google or Mi Account synced, the information will be lost irretrievably.

5. Checking hardware faults

If the software methods didn't work, the problem is probably hardware, and here are the most common malfunctions and their signs:

• 🔊 Membrane damage speaker: The sound is distorted, wheezing or crackling is heard, often after a phone falls or moisture is hit.
• 🔌 Contact detachment: Dynamics work and don't (especially after a light impact on the body) Typical for post-disassembly devices.
• 💧 Corrosion after liquid is ingested: The sound becomes very quiet or disappears completely.
• 🔋 Audio codec malfunction: Both speakers are quiet, microphone problems.

How to check the hardware on your own:

1. Speaker test: Call your phone from another device, if you're hearing you normally but you're not, the speaker problem is, if you're not, the microphone is faulty.
2. Vibration test: Turn on the music at maximum volume and put your finger on the speaker grille. If there's vibration but the sound is quiet, the membrane is damaged.
3. After-disassembly inspection: If you have experience, carefully remove the back cover (on non-removable battery models, such as the Xiaomi 12 Pro, it is more difficult).

⚠️ Attention: Disassembling Xiaomi phone without experience is fraught with damage to the plumes or battery. If you are not sure, you should contact the service. IP53/IP68 (for example, Xiaomi 13 Ultra) disassembly breaks tightness, which may lead to loss of water protection.

💡

If a quiet sound appeared after the phone fell, do not shake it or knock on the body - this can aggravate the damage to the membrane.

6. Replace the speaker with your own hands

If you’ve diagnosed a speaker malfunction and are willing to replace it yourself, follow this instruction. The example is given for the Redmi Note 10 Pro, but the process is similar for most Xiaomi models.

Tools required:

• 🔧 Plastic mediator or spatula for disassembly.
• 🔨 Cross screwdriver (usually) PH00).
• 🧲 Magnetic propeller substrate.
• 🔥 Hair dryer (for softening the glue on models with glued body).
• 🔊 New speaker (buy an original spare part or analogue from AliExpress, specifying the exact phone model).

Step-by-step:

1. Turn off the phone and remove it. SIM-map.
2. Heat the back cover with a hair dryer (on models with a glued body) or put it under the mediator (on models with a removable cover, for example, Redmi 9A).
3. Unscrew all the screws holding the metal plate over the battery.
4. Carefully disconnect the battery plume (use a plastic blade to avoid damaging the contacts).
5. Find the speaker (usually located at the bottom next to the USB-C connector) and unplug its plume.
6. Install a new speaker, plug in the plume and assemble the phone in reverse order.

Important: On dual-speaker models (such as the Xiaomi 11T Pro or POCO F4 GT), check both modules. Often, the top speaker fails, as it is smaller and more vulnerable.

💡

If the speaker is not restored after the replacement, the problem may lie in the audio codec on the motherboard, in which case professional diagnosis is required.

7. When to contact the service center

Not all sound problems can be solved by yourself, but here are some cases when you should definitely contact the service:

• 💦 The phone fell into the water or was subjected to severe humidity (even if there is no external trace of corrosion).
• 🔧 After disassembly, the sound disappeared completely or distortions appeared.
• 🔊 Both speakers are quiet and resetting the settings did not help (possible malfunction of the audio codec).
• 🔋 The phone does not turn on after trying to replace the speaker.
• 📱 The warranty is still valid (self-repair cancels warranty obligations).

The cost of repair in official Xiaomi services:

Before the service visit:

1. Make a backup of the data (even if the phone is turned on).
2. Check if there is an official Xiaomi service center in your city.
3. If the warranty is in place, don’t say you’ve tried to repair your phone yourself.

8. Prevention of sound problems

To avoid repeated problems with speakers, follow these guidelines:

• 🚫 Avoid moisture: Even if your Xiaomi has protection IP53/IP68, Do not expose it to prolonged water. Once moisture is in, turn off the phone immediately and dry it in rice or silica gel on it. 24–48 hours.
• 🧹 Cleaning regularly: Blow the speakers with compressed air once a month (especially if you carry your phone in your pocket with pile or sand).
• 🎵 Volume Control: Do not listen to music at maximum volume for a long time – this can cause overheating and membrane deformation.
• 📦 Use speaker-protected covers: Some cases (such as those from Spigen or Ringke) have special cutouts to prevent dust from getting in.
• 🔄 Update the firmware: Install the latest versions MIUI, They often contain corrections for sound bugs.

If you often listen to music through your phone’s speakers, consider buying an external Bluetooth speaker or headphones, which will reduce the load on the built-in speakers and extend their lifespan.

💡

Even if the speakers work normally, check them at maximum volume every six months - this will help to notice the problems that are beginning.
