Why Xiaomi’s speaker doesn’t work and how to fix it yourself

You pick up the phone, but you don't hear him, or the sound is quiet, distorted, or gone? Speaker problems on Xiaomi are one of the most common problems faced by smartphone owners. The causes can be either software failures or hardware failures. In this article, we'll look at all possible scenarios, from basic checks to complex solutions that will help bring sound back without going to the service center.

It's important to understand that the speaker for conversations (aka "talk speaker" or "microphone speaker") is a separate module that is responsible only for transmitting the voice of the interlocutor. If you don't have it working, and the music, video and notifications are played normally through the main speaker, the problem narrows. We'll focus on this case, but also touch on other related problems.

Before you panic and carry your phone for repair, go through our checklist. 80% In some cases, the problem is solved for 10-15 I'll start with the simplest of things!

1. Check basic settings and physical damage

The first thing to do is to rule out the obvious reasons, and users often overlook the basics of the problem by spending time looking for complex solutions.

Start by visually inspecting your phone:

• 🔍 Check if the speaker is covered with a protective film or a cover, especially for new phones where the film can remain after unpacking.
• 💧 Check the headphone jack (if it is in your model) – sometimes the phone “thinks” that the headphones are connected, and turns off the speaker.
• 📱 Make sure there is no humidity message on the screen (relevant for protected models) IP53/IP68).

Next, go to the sound settings:

1. Open the Settings. → Sound and vibration.
2. Check the slider Loudness of the call - it should be at maximum.
3. Make sure that no Do Not Disturb or Quiet mode is activated.

If you don't make a sound after this manipulation, move on to the next step, but remember, 30 percent of the time, the problem is solved by simply cleaning the speaker of dust or removing the cover.

2. Reboot and reset sound settings

Audio system failures are often due to temporary software errors, and the easiest way to fix them is to restart the phone.

How to properly reboot Xiaomi:

1. Press the power button for 5-7 seconds.
2. In the menu that appears, select Reboot (not “Switch off”!).
3. Wait for the full shutdown and automatic switching on.

If the reboot didn’t help, try resetting the sound settings to factory:

1. Go to Settings → System and device → Additional → Resetting.
2. Select Resetting Sound Settings (not to be confused with a full reset!).
3. Confirm the action and restart the phone.

Make sure the problem isn't with the cover or the film |

Check the volume in the settings |

⚠️ Note: If the sound is completely lost after reset (including music and notifications), this may indicate a hardware malfunction.In this case, do not try to make a complete reset - you should contact the service immediately.

3. Checking the microphone and speaker through the engineering menu

If the basic methods didn't work, it's time to dig deeper. Xiaomi provides access to an engineering menu where you can test hardware components, including a speaker and microphone.

How to open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##4636##
3. Select Phone Information (or Testing in some firmware).

On the test menu:

• 🔊 Select Speaker – the test signal should sound.
• 🎤 Select Microphone – speak to the microphone, the screen should display the signal level.
• 📞 Select Receiver (Conversation Speaker) – Put the phone to your ear, you should hear the sound.

If the speaker is working in the engineering menu and it's not, the problem is probably the firmware or the call settings, and if the speaker is not working here, it's a sign of hardware failure.

4. Update firmware and rollback to factory version

Failures in the speaker often occur after updating MIUI. Xiaomi developers regularly release patches that fix such bugs, so first of all check the relevance of the firmware:

How to update firmware:

1. Go to Settings → About the phone → System update.
2. Click Check for updates.
3. If a new version is available, download it and install it.

If the problem has occurred after the update, you can try to roll back to the previous firmware version.

1. Download the desired version of MIUI from the official Xiaomi website (choose Stable, not Developer).
2. Go to Settings → About Phone → System Update → Three Dots (menu) → Select a firmware file.
3. Specify the downloaded file and confirm the installation.

⚠️ Note: Firmware rollbacks can cause data loss if you don't back up. Also note that after rollbacks, some features (such as the latest security updates) may stop working.

💡

Before updating your firmware, check other users’ reviews on forums (such as 4PDA or Mi Community).If many people complain about sound problems after a particular version, wait for the next update.

5. Hardware reasons: what breaks down in the dynamics of Xiaomi

If the software methods didn’t help, the problem is probably hardware, and the following components are most often broken in Xiaomi smartphones:

The most vulnerable models according to the statistics of service centers:

• 📱 Redmi Note 8/8 Pro – frequent problems with the microphone after falls.
• 📱 Poco X3/X3 Pro – weak conversational speaker, quickly clogged with dust.
• 📱 Mi 9/9T — Problems with plume dynamics due to thin body.

If you suspect a hardware malfunction, but do not want to immediately carry the phone to the service, you can try a temporary solution:

• Use hands-free mode or connect a Bluetooth headset.
• Try to gently tap on the phone body near the speaker - sometimes this helps to "revive" the departed contacts.

💡

If the phone falls, gets wet or has been subjected to severe vibrations (for example, in a car), the probability of hardware failure is 90%.

6. Alternative methods: debugging and third-party applications

If the standard methods don't work, you can try more advanced solutions. One of them is using the technology. ADB-audio-resetting commands.

How to reset audio settings via ADB:

1. Install. ADB-computer-driver.
2. Enable USB Debugging in the Developer Settings (Settings → About Phone → MIUI Version – Press 7 times, then return to Additional → For Developers).
3. Connect your phone to your PC and type in the command line: adb shell settings put global volume_music 15 adb shell settings put global volume_ring 15 adb shell settings put global volume_system 15 adb shell settings put global volume_voice 15

Another way is to use applications to diagnose sound, such as:

• 🔧 Phone Doctor Plus – Tests all sensors, including speaker and microphone.
• 🔊 SoundAbout – allows you to reassign audio outputs (for example, direct the sound of a call to the main speaker).
• 🎛️ Audio Tuner – for fine-tuning sound profiles.

If you use custom firmware (like LineageOS or Pixel Experience), the problem may be incorrect drivers, in which case only flashing to the official MIUI will help.

7.When to contact the service: signs of a serious breakdown

Not all problems can be solved on their own, but there are a number of signs that clearly indicate the need for professional repair:

• 🚨 The sound went missing after a phone drop or moisture hit.
• 🔥 Phone overheats when talking (may indicate audio codec problems).
• 🔊 The speaker makes wheezing, crackling or whistling even in the engineering menu.
• 📵 The problem arose after a failed firmware or disassembly of the phone.

The cost of repairs in official service centers Xiaomi:

• Replacement of the Speaker: 1200–2500 ₽.
• Microphone Replacement: 800–1800 ₽.
• Repair of the plume: 1500–3000 ₽.
• Replacement of audio codec: 3000-6000 ₽.

If your phone is warranty-free, don’t try to repair it yourself – this will void warranty obligations.

⚠️ Warning: Unofficial services often install unoriginal parts that can quickly fail. Always ask for a warranty for repairs and originality of parts.
