Xiaomi speaker does not work: full instructions for diagnosis and repair

Have you turned on your favorite track or are trying to take a call, but the speaker on Xiaomi is stubbornly silent? The sound problem is one of the most common malfunctions of Xiaomi, Redmi and POCO smartphones, but in 80% of cases it can be fixed independently without going to the service center. The reasons can be hidden in software failures (incorrect settings, application conflict) and hardware breakdowns (damage of the plume, oxidation of contacts).

In this article, we’ll look at all the possible scenarios for why Xiaomi lost sound, from the trivial accidental press of a button to serious damage to the motherboard. You’ll learn how to distinguish a software malfunction from a hardware one in 3 simple steps, which settings to check first, and when to really carry the phone for repair. And for owners of older models (for example, Redmi Note 4 or Mi A1), we have prepared some recommendations – their speakers are more likely to fail due to wear.

Basic diagnosis: Checking the obvious

Before you take your phone apart or reset your settings, make sure the problem isn't in the little things.

• 🔊 Make sure the sound isn't turned off. Press the physical volume button upwards, so you should have an adjustment scale on the screen. If it's not there, you might have a Volume Down button pinched (for example, because of the case).
• 🎧 Check the connected devices. Sometimes the smartphone automatically switches the sound to Bluetooth headphones or speakers, even if they are turned off. Open the notification curtain and turn off all Bluetooth devices.
• 🔕 Do Not Disturb Mode. Go to Settings → Sound. → Don't disturb and make sure the mode is off. Also check the schedule - it's possible the sound is off by the timer.
• 📱 Reboot. A common but effective way: hold the power button for 10 seconds before you turn it off, then turn it on again, and it will reset the temporary error of the sound driver.

If you've had the speaker work after that, the problem was the settings, but if you still don't have the sound, move on to the next section.

⚠️ Note: On some Xiaomi models (e.g, POCO F3 Or Redmi Note 10 Pro, there's a separate button to switch the sound profiles on the sidebar, and make sure it's not translated to the "No Sound" position).

2. Checking software sound settings

If the speaker doesn't work only in certain applications (like YouTube or WhatsApp), the problem is probably in the audio settings or the conflict of programs.

Step 1: Volume by category

On Xiaomi, volume is set separately for calls, media and alarms. Go to Settings → Sound → Volume and move all sliders to maximum position. Notice the speaker icon next to each slider — if it is crossed out, the sound for this category is turned off.

Step 2. Reset the sound settings

If you've changed the uniformity of sound (equalizer) or the spatial sound settings before, it could have caused a failure.

1. Open the settings → Sound → additionally.
2. Click Reset audio settings (or Restore by default depending on the MIUI version).
3. Confirm the action and restart the phone.

Step 3: Verification of App Permits

Some apps (like TikTok or Instagram) may lose access to the speaker after updates.

1. Go to Settings → Applications → Application Management.
2. Select a problem app (like YouTube).
3. Press Permissions → Sound and make sure access is allowed.

💡

If the sound is gone after connecting to a Bluetooth speaker, try forgetting the device in the Bluetooth settings and reconnecting it. Sometimes the smartphone hangs on the last connected audio output device.

3. Hardware diagnostics: how to check the speaker physically

If the software methods didn't work, it's time to check the hardware.

• 🔍 Grid speaker. Light a flashlight on the lower speaker grille (usually to the right of the connector) USB-C). If you see dust or debris, clean it gently with a soft brush or compressed air!
• 💧 Wet marks on models without protection. IP53/IP68 (Like Redmi. 9A or POCO M3) The ingestion of water can cause the speaker's contacts to corrosion, signs: green plaque on the board or under the bars.
• 🔌 3.5mm connector. If you use wired headphones, check the connector for contamination or mechanical damage. Put the headphones in and out several times, sometimes the contacts oxidize.

Dynamics test without disassembly:

To make sure that the problem is in the dynamics, and not in the plume or motherboard, do these steps:

1. Connect your headphones (wired or Bluetooth) and check if there is sound through them. If so, the problem is with the speaker or its connection.
2. Call your phone from another device, and if you have sound while you're calling, but you don't have sound when you're playing music, that's the media setting.
3. Record a voice message and play it back, and if the microphone is working and the speaker is not, the problem is localized.

If the speaker doesn't make any sounds even after the restart, there may have been a plume break or the speaker itself fails, in which case you'll need to disassemble the phone.

⚠️ Note: On Xiaomi models with stereo speakers (for example, Redmi Note 11 Pro or POCO F4) Check both speakers separately. Sometimes only the top speaker fails, or just the bottom speaker fails. For the test, play the music and alternately cover each speaker with your finger, so you know which one is not working.

4. Resetting and flashing

If the speaker stopped working after updating MIUI or installing a new application, resetting your settings or reinstalling the firmware will help.Warning: these actions will delete your data, so back up first!

Soft reset (without loss of data):

1. Go to Settings → About the phone → Reset settings.
2. Choose Reset all settings (not to be confused with Reset to factory!).
3. Confirm the action. The phone will restart, but the files and applications will remain.

Hard reset (full):

If the soft reset does not help, perform a full reset:

1. Open Settings → About Phone → Resetting → Delete all data.
2. Enter your password (if required) and confirm.
3. After the reboot, set the phone as new and check the sound.

Fastboot flashing:

If the problem occurred after the MIUI update, try rolling back to the previous version or installing the firmware again.

1. Download the official firmware for your model from the Xiaomi website.
2. Unpack the archive and connect your phone to your PC in Fastboot mode (hold Volume Down + Power when you turn on).
3. Launch the file. flash_all.bat (Windows and wait until it is completed.

💡

If the speaker doesn't work after flashing, the problem is almost certainly hardware, and 90 percent of the time it's damage to the plume or the speaker.

5. Repair with your own hands: when possible

If you are sure that the problem is in the hardware, and are ready to disassemble the phone yourself, here is what you can do without special skills:

• 🔧 Contact clearing speaker. Often the sound is lost due to oxidation of contacts on the speaker plume. Carefully disconnect the plume (it is fastened with a latch) and wipe the contacts with alcohol with a cotton swab.
• 🔊 Replace the speaker. Xiaomi speakers are inexpensive (from 200 to 800 rubles depending on the model), buy the original part and replace it, following the instructions for your model (youtube has detailed videos).
• 🔌 If the speaker is working but there's no sound, there may be a damaged plume connecting it to the motherboard, and then you'll need to replace it.

Repair tools:

• Plastic mediators or suction cups to remove the back cover.
• Screwdriver PH00 or T3 (depending on model).
• Tweezers and alcohol to clean contacts.
• Dryer or thermo-air station (for models with adhesive back cover).

For models with a non-removable battery (for example, Xiaomi 12T or POCO F5), disassembly is complicated - you will need to disconnect the battery to get to the speaker. If you are not confident in your abilities, you better contact the service.

⚠️ Note: On Xiaomi models with waterproof body (for example, Xiaomi 13 Pro or Redmi Note 12 Pro)+) When you disassemble yourself, you lose your moisture protection. If you're still disassembling your phone, check the leakproofness of the adhesive layer after you assemble it.

6. When to contact the service center

There are situations where self-repair is not possible or advisable.

• 🔥 The speaker does not work after a phone drop or moisture hit.
• 🔧 You disassembled the phone but couldn’t find the problem (e.g., the plume and speaker are visually serviceable but no sound).
• ⚡ On the motherboard, traces of a short circuit are visible (blackened or bloated elements).
• 📱 Phone warranty - self-repair cancels it.

How to choose a service center:

Xiaomi has official services in all major cities, check out Xiaomi Service. Alternatively, local workshops with good reviews. Average cost of repairs is the speaker:

Before the service visit:

1. Make a backup copy of the data (if the phone is turned on).
2. Check if the workshop has experience with your Xiaomi model.
3. Ask for a warranty for repairs (at least 3 months).

7. Prevention: how to prolong the life dynamics

To avoid future sound problems, follow these guidelines:

• 🚫 Avoid maximum volume. Constantly running the speaker at full power causes it to wear out, especially on budget models (Redmi 9, POCO M2).
• 💦 Protect from moisture, even if your Xiaomi has protection. IP53, Long-term exposure to moisture can damage the speaker.
• 🧹 Clean the speaker grille regularly. Use a soft brush or compressed air (not a vacuum cleaner!). Dust and debris clog the membrane over time, making the sound worse.
• 🔄 Update the firmware. In new versions. MIUI They often fix bugs in the audio driver, but check other users' reviews before updating, and sometimes new versions bring new bugs.

For models with stereo speakers (Xiaomi 11T, POCO F4 GT), it is especially important to avoid mechanical damage. When a phone falls on a hard surface, it is the upper speaker that often suffers, since it is located closer to the edge of the case.

💡

If you often listen to music through your phone's speakers, check the sound quality at maximum volume every six months. Wheezing or distortion is the first sign of wear and tear.
