Why there is no sound when recording a screen on Xiaomi Redmi – and how to fix it

Recording the screen on Xiaomi Redmi smartphones should be a simple procedure — but many users face the problem of video being saved and sound not being available. The reasons may lie in both the settings of the MIUI system and the hardware limitations of a particular model. In this article, we will analyze all possible scenarios, from a banal disconnected microphone to hidden restrictions at the firmware level.

It's important to understand that the problem is not universal. For example, on the Redmi Note 10 Pro, sound may not be recorded due to the MIUI 13 security policy, and on the Redmi 9A due to the lack of support for internal audio in the standard recorder, we will analyze each case separately, offer working workarounds and tell you how to check whether your model supports recording system sound at all.

1. Check the basic settings of screen recording

Before you sin on crashes or limitations, make sure you set up the recording function correctly.In MIUI, screen recording options are hidden deep, and many users miss key options.

Open the Quick Settings Panel (swipe down from the top edge of the screen) and find the Screen Record icon (if not, add it through the panel editing). Click on it and note three key parameters:

• 🎤 Microphone: Must be on if you want to record voice or surrounding sounds.
• 🔊 System sound: Most Redmi models do not have this option or are blocked (more on this in the next section).
• ⚙️ Recording quality: Choose High or Standard – Low quality can turn off soundtracks.

If the microphone icon is inactive or gray, the system does not detect the microphone (it may be disabled in the security settings). Check the permissions for the application Screen Record in Settings → Applications → Application Management → Screen Record → Permissions.

2.Why Redmi doesn't record system sound: MIUI limitations

Since MIUI 12, Xiaomi has blocked the recording of internal audio (system sounds, music, and game sounds) in the standard screen recording app on most Redmi models.

1. License Restrictions: Recording audio from apps (such as Spotify or YouTube Music) may violate the terms of use of these services.
2. Privacy protection: MIUI is positioned as a system with a focus on security, and recording system sound is considered a potential vulnerability.

Exceptions are flagship models (e.g. Redmi K50 Pro or Redmi Note 12 Pro+) where the feature can be unlocked.

If your model falls into the category "❌ No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no. No, no. No, no. No, no. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No).

⚠️ Note: On some firmware (for example, MIUI Global) the system audio recording option may appear in the settings but not actually work.

3. Hardware problems: microphone, speakers, connectors

If the sound isn't recorded even with the microphone on, the problem may be in the hardware.

• 🔇 Polluted microphone: Dust or moisture in the microphone hole (usually at the bottom of the case) can block the recording. Try to clean it carefully with a soft brush or compressed air.
• 🔌 Damaged 3.5mm connector: If you connect headphones with a microphone through AUX, Check the connector for damage or oxidation. On the Redmi Note 8 Pro and older, the connector often fails after a year of use.
• 📱 Fall or impact: After physical impact, the microphone plume or speaker may have left, in which case the sound will be absent from the calls.

To diagnose a hardware malfunction:

1. Start the recorder and check if the sound is recorded through the microphone.
2. Connect headphones with a microphone and repeat the recording of the screen – if the sound appears, the problem is in the main microphone of the smartphone.
3. Call another phone and ask if you can hear your voice. If you can't, the microphone is faulty.

If the microphone is running in the recorder but does not record the sound when the screen is captured, the problem is software (see next section).

4. Conflicts with applications and permissions

Sometimes the sound when you record the screen is blocked by other applications or incorrectly exposed permissions.

• 🎵 Music apps: Services like Spotify, YouTube Music or VK Music can block sound recordings for licensing reasons.
• 🔒 Antiviruses or optimizers: Programs like Clean Master or Avast sometimes block access to the microphone.
• 📱 Do Not Disturb: In the settings Sound and vibration → No Disturbance Can Be Enabled by Restriction on Sound Recording.

To avoid conflicts:

1. Close all background applications through the latest apps (swipe up with a delay).
2. Check permissions to Write screen in Settings → Applications → Application Management → Screen Recording → Permissions. Must be enabled: Microphone Storage Display on top of other apps

Settings → Battery and performance → Battery consumption management

If the problem occurs after you install a new app, delete it and check the recording again, often with modified firmware or MIUI tweaks being the culprit.

5. Bypassing constraints: how to record system sound on Redmi

If your Redmi model doesn't support system sound recording with standard means, there are a few workarounds.

Method 1: Using an external microphone

The easiest way is to connect an external microphone through a 3.5mm connector or a USB-C (with an adapter) and the sound will be recorded from the microphone, not from the system, but this is better than no audio at all.

• Headphones with microphone (for example, Xiaomi Mi Earphones Basic).
• External microphones like Boya BY-M1 (demand OTG-adapter).

Method 2: Applications for recording sound from the screen

Some third-party apps can bypass MIUI restrictions.

• AZ Screen Recorder (in settings, enable Indoor Sound Recording, but requires MIUI 12+ and may not work on all models)
• Mobizen Screen Recorder (registration required but supports recording of sound on some Redmis)
• DU Recorder (operating unstablely, but sometimes catches system sound)

Important: these apps may require additional permissions or display ads. Don't download them from unverified sources!

Method 3: Rooting and modifying firmware

For advanced users, rooting and installing a Magisk module with a sound recording patch works on most Redmi models, but:

• 🚨 Cancels the guarantee.
• 🔄 It can lead to unstable operation of the system.
• 🔒 Requires unlocking the bootloader (on some models, this is not possible without official permission from Xiaomi).

Instructions for experienced users:

1. Unlock the bootloader through the Mi Unlock Tool.
2. Install a custom recavery (TWRP).
3. Sweep through Magisk and install the Audio Record Patch module.

⚠️ Note: On models with a MediaTek processor (e.g. Redmi) 9A or Redmi 10C) rooting can cause a device to break down. 4PDA or XDA Developers for your specific model.

6. Alternative methods of recording screen with sound

If none of these methods worked, consider alternative approaches:

• 🎥 Recording from another device: Use a second smartphone or camera to capture the Redmi screen from the speakers. The quality will be worse, but the sound will remain.
• 🖥️ PC Mirror: Connect Redmi to your computer via scrcpy (free utility) and record the screen with sound through OBS Studio.
• 🔄 Firmware update: On some models (for example, Redmi Note 11 Pro)+) System sound recording appears after updating to MIUI 14.

For PC mirroring:

1. Enable USB Debugging in Settings → About Phone → MIUI version (click 7 times, then go back to Additional Settings → For Developers).
2. Connect Redmi to your PC and start scrcpy.
3. In OBS Studio, add the source Capture window and select the scrcpy window.

This method gives better quality than recording on the smartphone itself, but requires a computer.

💡

If you use scrcpy, add the --bit-rate 8M key to improve video quality and --no-audio if the sound is being recorded with distortion.

7. Frequent mistakes and how to avoid them

Many users make the same mistakes when trying to record a screen with sound.

• 🔕 System Disabled: Before recording, check that the media volume is not at zero (volume buttons on the right).
• 📴 In the Airplane Mode: In this mode, the microphone and speakers can be turned off.
• 🔄 Switching sound to speaker: If during recording the sound switches from headphones to the speaker, the microphone may turn off.
• 📱 Use of unofficial firmware: Castom firmware (such as LineageOS) often breaks the sound recording.

Also note:

• Stored file format: Some applications record video to.mkv, which may not play audio on some players. Convert to.mp4 via VLC.
• Codecs: If the sound is recorded but not played, try another player (e.g. MX Player with all codec support).

💡

Before recording, always check: 1) whether the microphone is turned on in the Quick Settings panel, 2) whether it is in the Do Not Disturb or On the Plane mode, 3) whether there is enough free space on the device (recording is interrupted if there is a lack of memory).
