Why Xiaomi Screen Recording Without Sound: Fixing the Problem

When you run a built-in screencaster on a Xiaomi smartphone, record a gameplay or instruction, and when you play it, you find that the audio track is missing, it is quite common. Users often believe that this is a hardware defect or a firmware bug, but in 90% of cases the problem lies in software restrictions or incorrect privacy settings. Android, which runs the MIUI shell or the new HyperOS, has strict rules regarding the capture of internal audio stream.

Many people forget that when a recording function is activated, the system requests a choice of sound source, and accidentally clicking the Cancel button or selecting the No Sound option blocks the recording at the root. In addition, some applications, especially streaming services and banking programs, use DRM protection, which physically prohibits the capture of video and sound from the screen to prevent piracy. Understanding these mechanisms is the first step to solving the problem.

In this article, we will take a look at all the possible scenarios why Xiaomi screen recording can go without sound, and provide step-by-step instructions for correcting the situation, learn how to properly set up the microphone to capture external sounds and how to circumvent system restrictions for legal purposes.

The main reasons for the lack of audio stream during recording

The root cause of silence in recorded video is often the choice of sound source at the time of recording start. When you press the Screen Record button in the notification curtain, Xiaomi's system gives a pop-up menu where you need to select the audio option. If it selects "No Sound" or "Only microphone" in a quiet environment, the final file will be silent. This is a basic setting that is easy to overlook when in a hurry.

The second major reason is the limitations of Android Security. Starting with certain versions of the operating system, Google has implemented strict rules for applications that want to capture the internal audio stream (system sounds, games, music).Some old or specific screencaster apps may not have the necessary permissions or simply do not support the capture of internal sound on your version of Android.

⚠️ Note: If you are recording videos from Netflix, Disney+ And if you have other secure services, sound and video can be black screen or silence, it's not a phone bug, it's a content protection system. HDCP.

Conflicts with other audio-based applications should also be considered: If a navigator or messenger that monopolized the audio channel is running in the background, the system recorder may not be able to access the audio stream, in which case it is recommended to close the background processes before recording begins.

Setting up the sound source in MIUI and HyperOS

To record successfully, you need to configure the settings correctly before the session begins. In the shells from Xiaomi, this process is unified, but has its own nuances depending on the version of the software. It is important not just to click "Start", but carefully read the pop-up prompts.

To set up the record correctly, follow the following steps:

• 📱 Open the notification curtain and find the screen recording icon".
• 🎙️ In the menu that appears, click on the microphone icon or the item "Sound settings".
• 🔊 Select the "Inner Sound" mode (to record game/system sounds) or "Microphone" mode (to record voice).
• ✅ Press the start button for recording.

Internal Sound mode is only available on Android 10 and higher devices, and if you have an older version of the system, this item may not be available and the phone will only record through the microphone, in which case the sound quality will depend on external noise and distance to the speaker.

⚠️ Warning: When choosing Microphone mode, the phone's speaker can turn down the volume or silence automatically to avoid acoustic feedback.

If you want to record a conversation in a messenger (for example, Telegram or WhatsApp), you should definitely choose the “Microphone” mode, since capturing the internal audio stream during the call is technically impossible due to the busyness of the audio channel by the communication application itself.

💡

For better voice recording through a microphone, turn off noise cancellation in the sound settings if such an option is available in your model, or use an external headset.

DRM and Protected Content Limitations

One of the most common reasons why Xiaomi screen recording goes without sound or with a black screen is the digital content protection technology DRM (Digital Rights Management). streaming platforms such as Netflix, Amazon Prime, Hulu and even some sections of YouTube use this technology to prevent illegal copying of movies and TV shows.

When you try to start recording a screen while watching a secure video, Android security blocks the output of the video stream to the screencaster buffer, which results in either a completely black screen or a video without a soundtrack, this behavior is standard and cannot be changed by standard means without root rights and deep modification of the system, which is not recommended for ordinary users.

List of applications that often block the record:

• 🎬 Netflix and other video services.
• 🏦 Banking applications (card data protection).
• 💬 Incognito mode in browsers.
• 📞 Video Calling Applications (Zoom, Skype - Partially).

There is also the concept of audio focus. In Android, one application can monopolize the audio output. If a video player has captured the focus to play a movie, the system recorder may simply not access the audio stream to record, even if the DRM is not activated on a particular video.

Problems with permissions and access to applications

Sometimes the system simply forgets to give the Screen Record application the necessary permissions after updating the firmware or resetting the settings. Without the right to access the microphone or file system, recording sound is impossible. Permission verification is a mandatory diagnostic step.

Go to Settings → Applications → All applications, look in the Screen Recorder list. Make sure the application has permissions to use the Microphone and access Memory activated. If the slider is turned off, the system will ignore the request to record the sound.

It’s also worth checking if you have a third-party recorder that conflicts with the built-in one. If you use third-party software (like AZ Screen Recorder), make sure the right audio source is selected in its settings. Xiaomi’s built-in app is usually more stable, as it has deeper access to MIUI system resources.

Third-party screen recording applications

If Xiaomi’s standard tool doesn’t meet your requirements for some reason (for example, you need to record sound from a website in a browser where the built-in recorder fails), you can use third-party solutions.

Popular apps that are worth trying:

• 📹 XRecorder – has flexible bitrate and sound source settings.
• 🎥 AZ Screen Recorder – a classic solution with support for internal audio.
• 📱 Du Recorder – allows you to stream and record simultaneously.

When installing third-party software, be sure to provide all the permissions you request. Often, the no-sound problem is solved by simply reinstalling the application with a complete reset of its data. Go to Settings → Apps → [your recorder] → Clear the data, and then, when you first start, carefully monitor access rights requests.

Technical nuances and frequent errors

There are a number of technical issues that are rarely discussed in the instructions, such as when you connect a Bluetooth headset, the behavior of the audio stream can change. Some Xiaomi models redirect all the sound to the headset, and if the recorder is set to capture from the main channel, it can receive an empty signal.

Also worth mentioning is the effect of Do Not Disturb or No Sound mode, if the phone is in total silence, the system sound may not play, and therefore there is nothing to record, and make sure that the media volume is at least 30-40% unscrewed before recording.

Another common mistake is trying to record during an incoming call. Cellular network takes precedence over multimedia. At the time of the call, the audio channel switches to voice communication, and the screen is either interrupted or continues without sound. This is a limitation of GSM/LTE telephony that cannot be circumvented software.

⚠️ Warning: Do not attempt to record the screen and make a video call at the same time in the messenger with the microphone turned on. Android system does not know how to mix two incoming audio streams (from the call and from the recorder), one of them will be silenced.

💡

The main reason for the lack of sound is the wrong choice of source (Microphone instead of Internal sound) or blocking. DRM-protection.
