Screen recording on Xiaomi smartphones is a handy feature for creating guides, streams or saving game moments. But many users face an annoying problem: the sound begins to stutter, interrupt or distort, while the video remains smooth, a problem that is typical for most models of the brand – from the budget Redmi Note 12 to the flagship Xiaomi 14 Ultra.
What is the reason for this behavior? The culprits can be both hardware limitations (for example, a weak processor or a lack of RAM) and software bugs - from incorrect codec settings to conflicts with the system. MIUI. In this article, we will analyze all possible causes of sound stuttering when recording a screen on Xiaomi, as well as give step-by-step instructions for their elimination - from simple settings to radical methods like resetting the system.
Importantly, the problem isn't always about the curve of the firmware, sometimes it's third-party applications, background processes, or even physical damage to the speakers, and we can help you identify the root of the evil and choose the best solution.
1. Hardware Limitations: Why Iron is to blame for the sound stuttering
The first thing to check is the hardware capabilities of your smartphone. 9A POCO C50) They are equipped with weak processors (Helio). G25, Snapdragon 4xx), They just can't handle screen recording, video encoding and sound processing at the same time.
Signs of hardware problem:
- 🔊 The sound only stutters when recorded in high resolution (for example, 1080p 60 FPS).
- 📉 Lags appear after 5-10 minutes of recording (processor overheating).
- 🎮 The problem is made worse in heavy games (Genshin Impact, Call of Duty Mobile).
How do you check? Start recording the screen and open the multitasking menu at the same time (the "Recent" button), and if the interface starts to slow down, it's definitely the hardware.
- 📱 Downgrade the recording permission to 720p or 480p.
- ⚙️ Disable background apps before recording (see Section 3).
- ❄️ Use a cooling stand or play in a cool room.
2. Software bugs MIUI: Is it firmware's fault?
MIUI — Xiaomi's signature shell, known for its "chips" and... bugs. The stuttering sound when recording a screen is often associated with:
- 🐛 Errors in the MediaRecorder module (responsible for sound capture).
- 🔄 Conflicts after update MIUI (Especially relevant for bet versions).
- 🎵 Incorrect operation of the AudioFlinger sound driver.
How do you diagnose? Check if there's a problem.
- 🔹 Only when recording through the standard Screen Recording app.
- 🔹 Also in third party programs (for example, AZ Screen Recorder).
- 🔹 After resetting the settings to the factory.
If you only have stuttering in a standard app, it's the firmware's fault.
- Update. MIUI Up to the latest stable version (Settings) → The phone. → Updating the system).
- Clear the cache of the Screen Record application (Settings) → Annexes → Application management → Screen recording → Clear the cache).
- Install an alternative recorder (see section 5).
💡
Before the update MIUI Backup your data through Settings → Additionally. → Backup and reset. Newer versions of firmware sometimes reset the sound settings.
3. Background Processes: Who Steals Resources from Recording?
Even on powerful Xiaomi smartphones, background apps can overload the processor, causing the sound to break.
- 📱 Messengers (Telegram, WhatsApp) with active synchronization.
- 🎮 Game launchers (Xiaomi Game Turbo, Google Play Games).
- 🔄 Auto-Update Apps in Google Play.
- 📊 System services (com.miui.analytics, com.xiaomi.midrop).
How to check? Open Task Manager (Settings) during recording → Annexes → Application management → Running and see which processes consume the most CPU. If there are unnecessary apps hanging there, close them.
Close all background applications|Disable autosynchronization (Settings) → Accounts)|Turn off Game Turbo (Settings) → Special facilities → Game Turbo)|Put the phone in "Do Not Disturb" mode"-->
Radical Method: Enable Developer Mode and Limit Background Processes:
- Go to Settings → About Phone → MIUI version and tap 7 times on the build number.
- Back to Settings → Additionally. → For developers.
- Find the option to Limit Background Processes and select Process Maximum 2.
⚠️ Attention: Restricting background processes may cause notifications to be missed in messengers. After recording, return the settings to the original state.
4. Sound settings: codec, bitrate and other parameters
Incorrect audio settings are one of the most common causes of stuttering. Xiaomi uses compression to save space by default, but this often leads to artifacts.
| Parameter | Recommended value | Where to change |
|---|---|---|
| Sound format | AAC (not MP3!) | Screen recording settings → Sound quality |
| Bitrate sound | 192-256 kbit/s | Third-party recorders (such as Mobizen) |
| Sound source | Internal sound (not a microphone!) | Recording settings → Source |
| Frequency of sampling | 44.1 kHz (not 48 kHz!) | For advanced users (requires) ADB) |
If your recorder does not have manual settings, try turning off sound compression through ADB:
adb shell settings put global screenrecord.audio.encoder aac
adb shell settings put global screenrecord.audio.bitrate 256000Critical information: Some Xiaomi models (e.g. Redmi Note 10 Pro) record sound with a bitrate of 96 kbit/s by default, which causes a stutter. ADB root.
5. Third-party recording apps: Which is better than a standard recorder?
Standard application Screen recording in MIUI It's often unstable. Alternative recorders offer more customization and sometimes better sound.-3 tested applications:
- 📱 AZ Screen Recorder – supports recording internal sound without root, there are bitrate settings.
- 🎥 Mobizen – Optimized for gaming, minimal lag.
- 🔧 DU Recorder – allows you to select a codec of sound (AAC, MP3).
How to set up AZ Screen Recorder for stable sound:
- Open the app and go to Settings → Video quality.
- Select Bitrate of Sound: 256 kbit/s.
- Turn on the option to record the internal sound.
- Turn off the sound enhancement (may cause delays).
⚠️ Attention: On Xiaomi with MIUI 14+ Some recorders require additional permissions to record internal sound. If the sound is not being recorded, check settings → Sound-access applications.

6.Conflicts with Bluetooth and headphones
If you are recording a screen with Bluetooth headphones (AirDots, Sony) WH-1000XM5), the sound may stutter:
- 🔌 Unstable connection (interference, weak signal).
- 🎧 Low bitrate Bluetooth codec (SBC instead AAC or).
- 📱 Bluetooth and Wi-Fi conflict (both operating at 2.4 GHz).
Decisions:
- 🔗 Turn off Bluetooth headphones before recording or use wired ones.
- 🔄 Switch the Bluetooth codec to AAC (Settings → Bluetooth → Sound settings).
- 📶 Turn off Wi-Fi if you use Bluetooth (reduce interference).
If the problem only occurs with specific headphones, check them on another device.
7.Overheating and trottling: why the smartphone "strangles" sound
When you record a long screen (especially in games), the Xiaomi smartphone can overheat, which causes the processor to automatically reduce performance (trottling).
- 🔥 Stuttering sound (the processor does not have time to process the audio stream).
- 📉 Fall. FPS video.
- ⚡ Quick battery discharge.
How to check for overheating? Install the app CPU Monitor AIDA64 And look at the temperature of the processor as you write it down.°C - trottling is activated.
Ways of fighting:
- ❄️ Remove the cover before recording (will improve cooling).
- 🔋 Lower the brightness of the screen to 50–60%.
- 🎮 Turn off Game Turbo (Settings) → Special facilities).
- 🔄 Use Performance Mode instead of Balanced (Settings) → Battery → Performance mode).
💡
On Xiaomi smartphones with Snapdragon processors 8xx (Xiaomi 13 Pro: Trottling starts at 70°C. On budget chips (Helio) G88, Snapdragon 4xx) — already at 55-60°C.
8 Radical methods: reset, firmware, root
If none of the above has worked, there are extreme measures:
| Method | When to apply | Risks. |
|---|---|---|
| Reset to factory settings | After updating MIUI install multiple applications | Data loss (do backup!) |
| Flashing to custom firmware (for example, Pixel Experience) | If bugs MIUI Not corrected by updates | Loss of warranty, risk of "bricking" |
| Getting root rights and manual editing build.prop | For experienced users, if you need deep audio settings | Security breach, problems with banking applications |
Instructions for resetting settings:
- Go to Settings → Additional → Backup and Reset.
- Select Settings Reset.
- Confirm the action (you will need to enter a password).
- After rebooting, set the phone as new and check the sound recording.
⚠️ Note: Some Xiaomi models (e.g. Redmi) K50) Resetting settings can lead to locking the bootloader.Untie the Mi Account from the device before resetting!
