Modern Xiaomi, Redmi and POCO smartphones have powerful multimedia capabilities that allow users to consume content, but also actively create it. One of the most popular features for gamers, bloggers and educators is the ability to capture what is happening on the device’s display. However, standard settings often capture only video, leaving the user without the ability to record system sounds or voice accompaniment.
In the MIUI shell and the new HyperOS, the company’s engineers have provided a flexible screencasting toolkit that is hidden in the Quick Action menu. The correct configuration of this module allows you to broadcast game sounds, music from apps or comments through the microphone without installing third-party software. Understanding the nuances of the audio stream will help avoid common mistakes when the video is produced silent.
In this guide, we will take a closer look at the activation algorithm, microphone sensitivity settings, and output file quality options, learn how to avoid conflicts with other applications, and why recording sound can be blocked by Android security in some cases.
Activation of the function through the notification curtain
The fastest way to start capturing what's happening on the display is to use the built-in widget in the control panel. On most current Xiaomi models, this tool is pre-installed and does not require additional activation in the deep settings menu.
Find an icon called Screen Recorder or Screen Recorder. If you can't find it visually, click on the edit button (usually three dots or a pencil icon in the corner of the curtain) and drag the desired shortcut to the active panel. Once the application is launched, a floating control menu will appear on the screen.
This floating window is where the critical switches are. Before you start recording, you have to click on the settings icon (cog) or select the sound source immediately. By default, the system can offer No Sound mode, so manually selecting the Sound parameter is a must.
- 🎙️ Microphone: Records external sounds and your voice through the bottom hole of the body.
- 🔊 System sounds: captures the internal audio stream (music, game effects) in digital quality.
- 🔇 Switched Off: Video will be created without any audio track.
⚠️ Note: System audio recording may not be available or work incorrectly in some banking applications and streaming services due to security DRM-content.
Configuring the quality and format parameters
To achieve a balance between file size and visual clarity, you need to properly configure the encoding settings. In the recorder settings menu (Settings → Record quality), the user can choose resolution, frame rate and bitrate. High values provide a better picture, but fill the internal memory faster.
The best choice for most scenarios is the resolution corresponding to the native screen of your smartphone and the frame rate of 60 FPS. This is especially true for recording dynamic games, where the smoothness of the picture plays a crucial role. If the priority is to save space, you can reduce the bitrate to 12 Mbps.
The save format deserves special attention. Modern versions of MIUI allow you to choose between MP4 and GIF. MP4 is only suitable for video with sound, while GIF is used to create short silent animations.
| Parameter | Recommended value | Influence on the file |
|---|---|---|
| Permission | 1080p (FHD) | High definition, medium size |
| Frequency of personnel | 60 FPS | Maximum smoothness |
| Bitreit | 12-20 Mbps | Quality of detail |
| Format | MP4 | Compatible with all players |
💡
To record high-resolution gameplay, make sure that at least 2-3 GB is free on the drive to avoid interrupting the process.
Features of recording internal sound and microphone
The technical implementation of audio capture on Android has its limitations, which directly affect the result. When you select the source of System Sounds, the smartphone redirects the digital audio stream directly to the video file. In this mode, the microphone usually turns off to avoid echoes and feedback.
If you choose Microphone mode, the device records everything the sensor hears: your voice, keyboard noise and the sounds played by the phone speaker, the quality of this audio depends on the external conditions and the sensitivity of the hardware components.
There is an important nuance regarding simultaneous recording: standard Android 10 and higher means are forbidden to mix internal sound and microphone simultaneously in the same stream. Simultaneous recording of system sound and voice through the microphone with native MIUI means is impossible without the use of specialized third-party applications with deep access rights.
- 📱 Games: Use system sound for clean audio track of the game.
- 🗣️ Learning: Choose a microphone for voice explanations.
- 🎵 Music: Only system sound will preserve the quality of the track.
⚠️ Warning: When you switch audio sources during active recording, the process may automatically stop.
Use of third-party applications for advanced functions
In situations where the built-in functionality of Xiaomi is not enough, specialized applications from Google Play come to the rescue. Programs like AZ Screen Recorder or XRecorder offer more flexible audio mixer settings, allowing in some cases to bypass standard OS restrictions.
These applications often require special permissions through the ADB or special features menu. Once installed and granted, you can access the on-screen drawing, the webcam in the corner (picture-in-picture) and more advanced bitrate management.
However, it is worth considering that third-party software can consume more CPU resources and drain the battery faster. In addition, advertising in free versions can interrupt the recording process.
Popular Alternatives to the Standard Recorder
Where do files are saved and how to share them?
Once the writing process is complete, the file is automatically stored in the device gallery. The standard path to the directory is like Internal Memory./DCIM/ScreenRecorder or MIUI/screen_recorder. Depending on the shell version, files can also be duplicated in the shared Video folder.
To quickly access the latest recordings, open the Gallery app and go to the Album tab, where you create a separate album with video recordings of the screen, from which you can edit the video, cut off extra seconds or send it directly through instant messengers.
If you plan to upload content to YouTube or other platforms, pay attention to the orientation of the video. Horizontal recording (16:9) is preferable for classic videos, while vertical recording (9:16) is ideal for TikTok and Shorts.

The Solution: Why There's No Sound or Video
The most common problem users have is the lack of audio track in the finished video, which often happens when a high-priority incoming call or system notification is received during the recording, which temporarily intercepts the audio channel, and the reason may be the work of "energy savings".
If video is slow or has a low FPS, try lowering the recording quality in the settings. 4K recording on average Redmi or POCO models can put an excessive load on the video processor, causing frame skipping. Close background applications before starting an important recording.
In rare cases, the recording module can freeze. The solution is to clear the cache of the application Record the screen through the application management menu or simply restart the smartphone. Remember to update the system software, as Xiaomi regularly releases patches that improve the stability of the multimedia.
⚠️ Warning: Do Not Disturb mode does not always block system recording sounds; it is better to manually disable messenger notifications before starting the process.
💡
Stability of recording directly depends on free RAM and the absence of background processes consuming resources.
