Modern Xiaomi and Redmi smartphones have turned into powerful multimedia centers capable of not only reproducing content, but also creating it. The function screen capture (screencast) has become indispensable for gamers, bloggers and those who need to fix a bug in the application or save an important lesson. However, users often have difficulty activating the audio track: standard recording can take place without sound, or capture only system noise, ignoring the user's voice.
In this article we will analyze in detail the algorithm of actions for devices based on the MIUI shell and the new HyperOS. You will learn how to properly configure built-in recorderwhat hidden settings exist for volume balance and what to do if the standard functionality does not cope with the task. We will also analyze the impact of Android versions on the availability of the microphone during recording.
First, make sure your device is updated to the latest available software version. The control panel interface may vary slightly depending on the model Redmi Note or series Redmi K, but the basic principles of operation remain the same for the entire Xiaomi ecosystem.
Built-in screen recording tool: activation and configuration
Xiaomi has integrated a high-quality screencasting tool directly into system shell, eliminating the need for users to download dubious software. To activate this feature, simply swipe down from the top edge of the display to open notification curtain. Among the quick access icons, find the Screen Recording icon (usually it looks like a video camera). If you don’t see it in the first row, swipe right or click on the pencil to edit the tiles.
After clicking on the icon, a floating recording control menu will appear on the screen. This is where the key sound settings lie. By default, the system may offer a "Mute" or "System Sounds" mode, which is not suitable for creating full-fledged videos with commentary. You need to click on the microphone or gear icon in this menu to open the audio source options.
Select the option Microphone or System sounds and microphoneif your version of MIUI supports mixing. This will allow you to record what is happening on the screen at the same time as your voice. Please note that in older versions of Android (below 10), simultaneous recording of internal sound and voice may have been blocked by software.
⚠️ Attention: When selecting the audio source "Microphone", the recording will capture all surrounding noise, including notifications messengers and keyboard sounds. It is recommended to activate the “Do not disturb” mode before starting recording "Do not disturb".
Before starting recording, wipe the microphone hole on the smartphone body. Even a small amount of dust can make the voice on the recording muffled and unintelligible.
Setting up sound sources and volume balance
One of the main problems when recording gameplay or tutorials is volume imbalance. Often the system sounds of the game drown out the voice of the commentator, or vice versa - speech can be heard perfectly, but the actions on the screen take place in silence. In the settings of the Screen Recording application (which can be found in the shared Tools folder), there is an advanced section for calibration.
Go to the recorder settings and find the “Sound Settings” item. Here you will see a slider that allows you to adjust the volume ratio. By moving it, you can prioritize internal audio devices or microphone input. For let's plays, the optimal ratio is considered to be where the system sound is about 70-80%, and the voice - 20-30%.
It is also worth paying attention to the noise reduction function. On some Redmi models, it is enabled by default and may incorrectly cut off the low frequencies of your voice, making your speech sound robotic. If you notice this effect, try turning off the “Sound Enhancement” option in the same settings.
- 🎙️ Microphone: Records only your voice and surrounding sounds, ignoring audio from applications.
- 🔊 System sounds: Captures clear digital audio from games and videos, but without commentary.
- 🎚️ Mixing: Allows you to mix both sources, requiring manual balance adjustment.
Features of sound recording in different versions of MIUI and HyperOS
The interface and audio capture capabilities have evolved significantly with the release of new versions firmware. Users of older devices based on MIUI 11 or MIUI 12 could encounter limitations when recording internal sound was available only for certain applications or required root access.
Starting with MIUI 13 and in the current HyperOS, algorithms for working with sound have become more flexible. The system now automatically detects the type of content: if you launch a video player or game, the option to record system audio becomes active. However, due to licensing restrictions, this feature may be hidden in some regions.
If you upgraded your phone but the audio recording feature is no longer available, check your device region. Sometimes changing the region in the settings (Settings → Advanced settings → Region) to “India” or “Singapore” returns the full functionality of multimedia tools, although this method is a temporary solution.
| Shell version | System audio recording | Microphone recording | Simultaneous recording |
|---|---|---|---|
| MIUI 10-11 | Limited / No | Yes | No |
| MIUI 12-13 | Yes (automatically) | Yes | Yes (with settings) |
| HyperOS 1.0 | Yes (improved) | Yes (noise reduction) | Yes (balance) |
⚠️ Attention: The settings interface may change with each security update. If you do not find the described items, check the official documentation for your specific model in the “Services” application.
Third-party applications for professional recording
In cases where the built-in functionality does not meet your requirements (for example, you need recording at 60 FPS with a high bitrate or specific codecs), you should turn to third-party solutions. The store offers many utilities, but not all of them work equally well with audio streams on processors. One of the market leaders is the XRecorder application from InShot. It allows you to flexibly configure the audio source, select resolution up to 1080p and frame rate. The main advantage of such apps is the ability to draw on the screen while recording and add a webcam on top of the main image. Google Play offers many utilities, but not all of them work equally well with audio streams on processors Snapdragon or MediaTek.

Another popular option is AZ Screen Recorder. This application is known for its stability and the absence of watermarks in the free version. It supports internal audio recording on Android 10 and above without the need for root access, which is critical for data security.
Why can third-party apps record better audio?
Third-party developers often use their own audio capture drivers, which can bypass some MIUI system limitations imposed on the standard screen recording API.
Troubleshooting: why there is no sound in the recording
The most common complaint from users is that the recording is created, but the audio track is missing or contains only silence. The first reason that needs to be ruled out is physical blocking of the microphone. Tight-fitting cases or screen protectors that cover the bottom hole can muffle sound.
The second reason lies in application permissions. Go to Settings → Applications → Screen Recording → Application Rights. Make sure the switch next to Microphone is active. Without this permission, the system blocks the recorder's access to the audio input for privacy reasons.
The third problem is related to protected content (DRM). When you try to record your screen while watching movies on Netflix, Disney+, or banking apps, the system automatically mutes the video stream and audio. This is not a malfunction, but anti-piracy protection built into the Android kernel level.
- 🔇 Check if silent mode or vibration is turned on when you start recording.
- 📱 Make sure that the “Microphone” source is selected in the recorder settings and not “None.”
- 🛡️ Remember that protected content (movies, banks) cannot be recorded with sound legally.
☑️ Diagnosing the absence of sound
Where to find and how to edit ready-made recordings
After the recording session is completed, the file is automatically saved in the device gallery. Usually a separate album is created with the name "Screen recordings" or ScreenRecorder. Files are saved in MP4 format, which is compatible with any video player and social network.
The built-in MIUI editor allows you to perform basic video trimming immediately after stopping recording. You can remove a bad start or a long ending without resorting to third-party software. For more complex editing, adding music or titles, it is recommended to use applications like CapCut or InShot.
The amount of memory occupied directly depends on the selected resolution and duration. A minute of recording at 1080p can take up 50 to 100 MB. It is recommended to regularly empty the folder with recordings or transfer them to a memory card if your Redmi supports storage expansion.
Screen recording files are saved in local memory and are not automatically synchronized with the cloud - be sure to back up important videos.
Is it possible to record a call with audio via screen recording?
On most modern versions of Android (10 and higher), recording telephone conversations through the standard screen recording function is blocked by system security restrictions. You will see the video, but the audio track will be empty. To record calls, use your phone's built-in call recording feature (if available in your region) or special applications that require complex setup.
Why does screen recording slow down in games?
Playing a game and video encoding at the same time places a high load on the processor and GPU. If you notice a drop in FPS, try lowering the recording resolution to 720p or the frame rate to 30 FPS in the recorder settings. Also close background applications before starting recording.
Is the sound of notifications recorded during the game?
Yes, if the “Microphone” source is selected, then all sounds, including instant messenger notifications, will be recorded. To avoid this, enable Do Not Disturb mode or set exceptions for notifications in the sound settings before starting screen recording.
