Mode without sound when recording on Xiaomi: causes and ways to disconnect

Have you ever encountered a situation where when you record a video on a Xiaomi smartphone, the sound suddenly disappears and the screen says "Mode without sound"? This feature often confuses users, especially if they are not aware of its existence. It is not actually a bug, but a special mode that can be activated automatically or manually.

In this article, we will discuss in detail what is the mode without sound when recording on Xiaomi devices, why it turns on and how to work with it. You will learn which models support this feature, how to turn it off or use it usefully. And we will talk about the hidden camera settings that can affect the sound in your videos.

What is a mode without sound when recording on Xiaomi

No sound mode is a feature that turns off the microphone while shooting a video, and it can be activated for several reasons, from the silent mode on the phone to special settings in the camera app, which users often notice by:

• 🔇 Icon speaker with crossed icon on recording screen
• 🎥 No sound in the finished video file
• 📱 No Sound Mode Notice at the top of the screen

This feature appeared in the firmware MIUI since version 12 and is actively used in models Xiaomi 11/12/13 series, Redmi Note 10/11/12 and POCO F/X. It is designed to prevent the recording of unwanted noise, but sometimes it works unexpectedly.

It's important to understand that recording no sound is not the same as turning off the sound on your phone, and even if your smartphone is silent, the microphone usually keeps working when recording video, and it's about specifically turning off the audio capture.

Reasons for activation of the mode without sound

There are a few main reasons why your Xiaomi might go into no sound mode when recording:

1. Phone silent mode – in some versions of MIUI, this automatically turns off the microphone when recording
2. Camera settings – the “Record without sound” option can be enabled in the application
3. Activation through the notification curtain – a quick button to turn off the sound when recording
4. Application restrictions – some messengers (like WeChat) block sound when recording through the camera
5. Hardware problems – damage to microphone or contacts

The most common reason is Settings → Sound → Silent Mode, which many users don't know is that in MIUI, this setting affects not only notifications, but also video recording, and it can also activate when you plug in your headphones, the phone automatically switches to them to record sound, and if the headphones don't support the microphone, the sound disappears.

💡

Check if your Xiaomi has Bluetooth headphones connected, and even if they are turned off, the system can “think” they are active and turn off the main microphone.

How to turn off the mode without sound when recording

If you want to return sound to your videos, follow this step-by-step instruction:

First, make sure your phone is not in silent mode.

1. Swipe down from the top edge of the screen to open the notification bar
2. Find the speaker icon with a crossed icon
3. Touch it to bring back the sound.

If this doesn’t help, go to the camera settings:

1. Open the Camera app
2. Touch the gear icon or swipe left to open settings
3. Find the Video Recording or Sound section
4. Turn off the option of recording without sound or video only

On some models (Xiaomi 13 Pro, Redmi Note 12 Pro+), this setting may be in the section Additional → Record Modes. If you do not find the right setting, try resetting the camera settings to factory:

1. Go to Settings → Applications → Application Management
2. Find the camera on the list.
3. Select Warehouse → Clear the Data

Xiaomi models with support for this feature

Not all Xiaomi devices are available with no audio recording, but here is a table with models that support this feature:

On POCO and Redmi devices of earlier series (before 2021 release), this feature is usually not available, and it may not be available on devices with custom firmware or global versions of MIUI for some regions.

An important feature: on Xiaomi 13 Ultra, the soundless mode is activated automatically when shooting in 8K mode, since processing the audio stream requires additional resources.

Hidden camera settings that affect sound

In addition to the obvious parameters, the sound of recording video can be influenced by hidden settings.

• 🎤 Sound source: In some firmware, you can choose which microphone to record the sound from (main, top, bottom)
• 🔊 Sound amplification: the option can automatically turn off the microphone at high noise levels
• 📱 Power saving mode: when activated, may limit microphone performance
• 🔒 Application permissions: check if the Camera app has access to the microphone

To access hidden settings:

1. Open the Camera app
2. Go to Additional → Video Settings
3. Tap 5 times according to the application version (bottom of the screen)
4. There will be a menu for developers with additional parameters

In this menu you will find options for:

• Choosing audio bitrate (affects sound quality)
• Noise reduction settings (can turn off the microphone when the signal is weak)
• Control hardware acceleration (sometimes conflicting with sound recording)

💡

On Xiaomi 12T Pro, there is a separate “Audio in 4K” switch in the hidden settings, which is disabled by default to save resources.

Frequent Mistakes and How to Avoid Them

Many users unwittingly activate the mode without sound, and here are the most common errors:

⚠️ Warning: If you use a magnetic lock case, it can activate the no sound mode when recording. This is because some cases simulate the closure of the lid, which the system perceives as a command to turn off the microphone.

Other common mistakes:

• 🔄 Fast switching between cameras – can knock down the sound settings
• 📲 Use of third-party launchers – some of them block system functions
• 🔋 Battery discharge below 15% – activates power saving mode that can turn off the microphone
• 🎧 Connect headphones — even if they are not used for recording

To avoid these problems:

1. Before recording, restart your phone.
2. Turn off all unnecessary Bluetooth devices
3. Use the original MIUI launcher
4. Watch the battery level.

If the problem persists, try recording the video in another app (like Google Camera or Open Camera) to help determine if the problem is with the system camera or hardware.

Alternative methods of recording sound

If the no-sound mode is constantly activated and interferes with your work, consider alternative options:

• 🎙️ External microphone – connects via USB-C or Bluetooth
• 📱 Second device – record the sound on another phone or recorder
• 🎥 Specialized applications – FilmoraGo, KineMaster have their own audio settings
• 💻 Screen recording – via Settings → Additional → Screen recording

For professional photography, we recommend using external microphones:

• BOYA BY-M1 is a compact lavier microphone
• Rode VideoMic - Directed Microphone for Video
• Sony ECM-LV1 – a wireless microphone with low noise level

When using external microphones, do not forget:

1. In the camera settings, select the correct sound source
2. Disable built-in noise cancellation (it may conflict with external equipment)
3. Check the volume levels in real time

💡

To connect professional microphones to Xiaomi, you may need a USB-C hub with a 3.5mm port or a Lightning-to-3.5mm adapter (for older models).
