No sound on Xiaomi phone: what to do if the speaker, headphones or microphone does not work

You turned on the video on Xiaomi Redmi Note 12, but instead of music there is silence. Or a call comes in, but you can only hear the interlocutor through the speakerphone. Situations when Sound disappears on an Android smartphoneare familiar to many device owners Xiaomi, POCO or Mi. The reasons can be either software (software failure, incorrect settings) or hardware (damage to the speaker, oxidation of contacts).

In this article we will analyze all possible scenarios: from trivial errors in the settings to serious breakdowns requiring repair. You will learn how to diagnose the problem, which parameters to check first, and when to contact a service center. And also - unique features for Xiaomi smartphoneswhich are not written about in standard instructions (for example, how to reset sound settings through the engineering menu).

1. Checking basic sound settings

Before you panic, make sure that the problem is not in basic settings. On Xiaomi the sound may disappear due to:

• 🔇 Activated "Silent" mode (or "Do not disturb") - check the slider in the notification shade.
• 🎧 Connected Bluetooth headphones —the phone can automatically redirect sound to them, even if they are turned off.
• 📱 Errors in the sound profile —sometimes the smartphone “forgets” the current settings after updating MIUI.

To rule out these reasons:

1. Pull the notification shade down and check the speaker icon. If it is crossed out, tap on it.
2. Open Settings → Connected devices → Bluetooth and turn off all paired gadgets.
3. Go to Settings → Sound and vibration → Sound modes and select "Sound" (not "Vibration" or "Silent").

If after these manipulations the sound does not appear, proceed to the next step. Please note: on some models (for example, POCO X5 Pro) after updating to MIUI 14 the sound profile for individual applications (for example, YouTube or Telegram) may be reset. Check the sound settings directly in the problematic application.

2. Diagnosis of hardware problems

If the sound disappears in all applications (music, calls, notifications), there is a high probability of a hardware malfunction. The most common reasons:

• 🔊 Damage to the speaker - especially after a fall or moisture.
• 🔌 Oxidation of contacts on the speaker cable (typical for Redmi 9 and Redmi Note 10 after a year of operation).
• 🎤 Microphone/speaker contamination —dust or debris can block the sound.
• 🔋 Sound controller failure —rare, but occurs after unsuccessful firmware.

Carry out a quick diagnosis:

1. Check the speaker for physical damage: Hold the phone to your ear while playing music. If you hear wheezing or crackling, the speaker is damaged.
2. Test the headphones: connect them to the phone. If there is sound in the headphones, but not in the speaker, the problem is in the hardware.
3. Use the code for the test: enter in the telephone dialer ##4636##, select "Test hardware" → "Audio". If the test shows an error, this is a hardware malfunction.

What to do if the phone was dropped into water?

If the smartphone Xiaomi has been in contact with liquid, the sound may disappear due to corrosion on the board. In this case:

1. Turn off the device immediately.

2. Remove the SIM card and memory card.

3. Place the phone in a bag of silica gel (from a shoe box) for 24–48 hours.

4. Do not turn it on the device until it is completely dry.

If the sound is not restored after drying, the board needs to be professionally cleaned by a service center.

Attention! If the phone is stopped making sounds after falling or moisture penetration, do not try to disassemble it yourself. Modern smartphones Xiaomi (for example, Xiaomi 13 or POCO F5) have adhesive fastening of cables - unprofessional repairs can aggravate the problem.

3. Resetting sound settings through the engineering menu

On smartphones Xiaomi there is a hidden engineering menu where you can reset the sound settings to factory settings. This helps if the problem is caused by a software failure, but a normal reset did not help.

Instructions:

1. Open the application Phone and enter the combination: ##36446337## (may not work on some models - see alternative below).
2. In the menu, select Hardware Testing → Audio.
3. Press Reset Audio Settings (or a similar option).
4. Reboot the phone.

If the code does not work, try an alternative method:

1. Install from Play Market application MTK Engineering Mode (for MediaTek processors) or Qualcomm EngineerMode (for Snapdragon).
2. Open section Audio i select Reset.

Important: the engineering menu is intended for advanced users. Do not change other parameters if you are not sure of their purpose - this may lead to complete loss of sound or other failures.

4. Firmware update or rollback

Often the sound disappears after the update MIUI. For example, users Redmi Note 11 complained en masse about the lack of sound in calls after updating to MIUI 13.0.5. In such cases, it helps:

• 🔄 Rollback to the previous firmware version (if the update was recent).
• 📥 Installing the latest stable version (sometimes bugs are fixed in the next patches).
• 🧹 Clearing the system cache (helps with sound drivers freezing).

How to update the firmware correctly:

1. Go to Settings → About phone → System update.
2. Click on the three dots in the upper right corner and select Download latest version.
3. If the update does not help, try manual installation via Settings → Advanced → Update and recovery (select the firmware file format .zip).

To roll back the firmware:

1. Download the desired version MIUI from the official website Xiaomi (section "Fastboot" or "Recovery").
2. Use Mi Flash Tool for installation (instructions on official website).

Attention! Manual update or rollback of the firmware erases everything. data from the phone. First make a backup copy via Settings → Advanced → Backup and reset.

5. Checking application rights and software conflicts

Sometimes the sound disappears only in specific applications (for example, in WhatsApp or TikTok).This may be due to:

• 🚫 Blocked permissions access to the microphone/speaker.
• 🔄 Conflict with other apps (for example, managers sound or VPN).
• 📦 Failure in the application cache.

How to fix:

1. Open Settings → Applications → Manage applications.
2. Select the problematic application (for example, YouTube) and check the permissions: must be enabled Microphone and Sound.
3. Clear cache: click Storage → Clear cache.
4. If that doesn’t help, delete and install the application again.

Also check if the sound is being blocked battery optimizer. On Xiaomi it can limit the background running of applications:

1. Go to Settings → Battery and performance → Battery management.
2. Find the problematic application and select mode No restrictions.

6. Hard reset and contacting service

If none of the methods help, there are two options left:

1. Hard Reset —returns the phone to factory settings, but erases all data.
2. Repair at a service center —if the problem is hardware (the speaker, cable or sound chip is damaged).

How to make a Hard Reset:

1. Turn off the phone.
2. Press Power button + Volume up until the logo Mi.
3. In the menu Recovery select Wipe Data → Wipe All Data (control - volume buttons, confirmation - power button).
4. After the reset, the phone will reboot to factory default condition.

If this does not help, there is a problem 100% hardware. Contact the service center Xiaomi or verified repair. Average prices for speaker repairs:

Phone model	Cost of speaker repair (₽)	Cost of cable replacement (₽)
Redmi Note 10/11	1 200–1 800	1 500–2 200
POCO X3/X4	1 500–2 000	1 800–2 500
Xiaomi 12/13	2 500–3 500	3 000–4 000
Redmi 9/9A	800–1 500	1 200–1 800

Attention! If the phone is under warranty, do not disassemble it yourself this will void the warranty. Contact the official service center Xiaomi with a receipt and box.

7. Specific problems and solutions for Xiaomi

Smartphones Xiaomi have unique “features” that can affect the sound:

• 🔈 "Smart Assistant" blocks the sound: MIUI there is a function that automatically switches the phone to silent mode according to a schedule or geolocation. Check: Settings → Smart Assistant → Modes.
• 🎵 Crash in Mi Sound Enhancer: this is proprietary software for improving sound, but sometimes it “jams” the speakers. Disable it in Settings → Sound and vibration → Mi Sound Enhancer.
• 📡 Conflict with Dual Apps: if you cloned messengers (for example WhatsApp), notification sounds may disappear. Delete the clone or restart the phone.
• 🔋 Battery saving turns off the speaker: in Ultra saving some models (Redmi A1, POCO M4) limit the sound. Disable the mode in Settings → Battery.

Another one hidden problem — failure in service com.android.phone, which is responsible for calls. If the sound disappears only during calls:

1. Go to Settings → Applications → Manage applications.
2. Find Phone (or com.android.phone).
3. Clear cache and data, then restart the phone.

If calls are not restored after this, check whether the function Internet calls (VoLTE/VoWiFi) is activated. Sometimes it conflicts with your telecom operator. Disable it in Settings → SIM cards and mobile networks → Internet calls.

FAQ: Frequently asked questions about sound on Xiaomi

🔊 Why is there no sound in the headphones on Xiaomi, but there is sound in the speaker?

This is a typical problem with 3.5 mm connector (if it has one) or USB-C adapter. Reasons:

• Oxidation of contacts in the connector (clean with alcohol).
• Failure in sound output settings (try switching the type connected devices in Settings → Connected devices).
• Damage to the connector cable (repair required).

On models without 3.5 mm (for example, Xiaomi 13 Lite) the problem may be in the adapter - try another.

📞 There is sound in calls, but the interlocutor cannot hear me. What should I do?

This is a problem with microphoneCheck:

1. Is the microphone covered by a cover or finger (on POCO X5 it is located at the bottom, next to the USB-C connector).
2. Does the microphone work in other applications (for example, in a voice recorder).
3. Is the "Hands-free" mode activated during a call (turn it off).

If the microphone does not work nowhere - this is a hardware failure. On Xiaomi often fails bottom microphone (responsible for calls), the upper mientras (for noise reduction) may remain working.

🔄 After updating MIUI, the sound disappeared. How to return?

Updates MIUI often break the sound. Try:

1. Clear system cache: Settings → Storage → Clear cache.
2. Reset sound settings through the engineering menu (see section 3).
3. Roll back to the previous firmware version (if updating was recently).

If the sound disappeared after major update (for example, from MIUI 13 to MIUI 14), check the forums - perhaps this is a massive bug, and Xiaomi a patch has already been released.

💦 The phone fell into the water and the sound disappeared. What to do?

If the phone is contact with liquid, the sound may disappear due to:

• Corrosion on the speaker or microphone contacts.
• Damage to the cable (especially vulnerable to Redmi 9 and POCO M3).
• Short circuits on the board.

Actions:

1. Immediately turn off the phone and remove the SIM card.
2. Place it in a bag with silica gel for 48 hours (do not use rice!).
3. After drying, check the sound. If it doesn’t work, take it to the service for ultrasonic cleaning.

Do not turn on the phone until it is turned on. It will dry out! This may cause a short circuit.

🎧 There is sound in only one speaker (stereo). Why?

On smartphones Xiaomi s stereo speakers (POCO F4, Xiaomi 12 Pro) one of the speakers may stop working due to:

• Dirty speaker mesh (clean with a soft brush).
• Damage to the top speaker cable (often after a fall).
• There is a problem with the stereo sound settings (reset via the engineering menu).

Check the sound balance: in some firmware MIUI there is a separate setting for the left/right speaker balance in Settings → Sound → Balance stereo.
