When you turn on your favorite TV series or movie, you are faced with complete silence, can spoil the mood of any user. The lack of audio on Xiaomi TVs running Android TV is a common problem that can be caused by a software failure, improper settings or hardware malfunction. Before panicking and looking for a service center, it is worthwhile to conduct a self-diagnosis, since in most cases the solution lies in the software part.
Modern Smart TV These are complex multimedia centers where a whole range of software and hardware components are responsible for playing audio, HDMI-Before you output the sound to the speakers or external speaker system, understanding how exactly the audio track of your model works, whether it is Xiaomi Mi. TV P1 Or more senior series, will help to localize the problem faster.
In this article, we will go into detail the algorithms that will help you get back sound. We will look at both basic remote and setting checks, and more complex methods, including resetting and flashing. A systematic approach to solving the problem will avoid unnecessary costs and restore the device to work in the shortest possible time without the need to call the wizard.
Primary Diagnostics and Verification of Physical Connections
The first step in fixing any malfunction is to eliminate the elementary causes. Often users accidentally press the Mute button on the remote control, completely turning off the sound, or reduce the volume to zero. Make sure that the indicators on the screen show an active volume level and there is no icon of the crossed out speaker.
If you use external signal sources, such as consoles, game consoles or laptops connected via HDMI, the problem may lie in the cable or port. Poor contact or damaged wire can lead to video transmission without audio. Try to switch the cable to another HDMI connector or replace it with a known serviceable one to prevent physical interface failure.
Special attention should be paid to connecting external acoustics. If previously a sound bar or home theater was connected to the TV via an optical output or ARC, the system could "mark" this priority and continue to send sound there even if the device is disabled, in which case you need to manually switch the output back to the built-in speakers through the settings menu.
Audio output setting and playback device selection
The Android TV operating system installed on Xiaomi TVs allows you to flexibly manage the routing of the audio stream. If the sound is lost only in certain applications or when watching specific content, the digital output settings are likely lost. You need to go to Settings β Device β Sound β Digital format.
It's important to choose the right audio stream format. For most embedded applications and television, PCM is the best option. If you have a powerful external audio system that supports surround sound, you can try switching to Auto or Pass-through, but often it is the PCM installation that solves the problem of lack of sound on the embedded speakers.
It is also worth checking the equalizer and sound effects settings. Sometimes activating specific modes, such as "Cinema" or "Sport", can lead to software conflicts of sound drivers, especially on older versions of firmware. Resetting sound settings to factory values often helps eliminate software artifacts.

Try temporarily connecting wired headphones in a 3.5 mm connector. If there is sound in the headphones, but there is no speaker - the problem is almost certainly in the software switching of outputs or malfunctioning of the TV amplifier.
Resetting and restarting the Android TV system
The accumulation of temporary files and cache in the operating system can lead to malfunctioning of system services, including audio drivers. Simple reboot of the remote (removing the batteries) does not help, since Xiaomi TVs often remain in deep sleep mode.
To do this, press the power button on the remote and select Reboot. If the menu is not available, you can turn off the TV from the power supply for 2-3 minutes, allowing the capacitors to completely discharge, this action resets static electricity and clears the system's RAM, which often solves the problem of "hang" sound.
If a simple reboot didnβt work, you can try a more radical method, resetting your settings to factory settings, remember that this action will delete all installed apps and accounts. Before starting the procedure, make sure you remember the logins and passwords for reauthorization.
βοΈ Checklist before resetting settings
β οΈ Before performing a full reset, make sure that the TV is connected to a stable power source. Interrupting the reset or upgrade process can damage the system partition and completely inoperable the device.
Updating or reinstalling firmware
The software of the TV is the foundation on which all functions work. Xiaomi developers regularly release updates to fix known bugs, including audio problems. You can check for updates in the Settings β Device β About System β System Update.
Sometimes the built-in update engine won't find a new version due to server errors or regional constraints, and in such cases, you can use the method of manual firmware installation. To do this, you need to download the current firmware file for your specific model from the official site, write it down on the website. USB-storage device (formatted in FAT32) and start the installation via a menu or button combination.
It is important to understand that the firmware version must strictly conform to the model of your motherboard. Installing the wrong version can lead to the "bricking" of the device. Always check the model on the sticker on the back of the TV and check it against the name of the firmware file.

Diagnostics through the Engineering Menu and ADB
For advanced users who arenβt afraid to experiment, there is a possibility of diagnosis through debugging interfaces. Android TVs allow you to connect to them over the network via the ADB (Android Debug Bridge) protocol, which gives you access to system logs where you can see audio driver errors in real time.
To enable debugging, you need to go to Settings β About System and click on βBuild Numberβ 7 times. After that, the option βDebug via USBβ will appear in the developer menu. Once you connect from your computer, you can execute a command to restart the audio service without fully restarting the TV.
There is also a hidden engineering menu that can be accessed through special applications or code input in the input field (if there is a physical keyboard), and in the engineering menu you can run a Speaker Test, which will force the test signal to ignore the software volume settings, which is the best way to check the hardware.
adb connect 192.168.1.XX
adb shell am start -n com.android.tv.settings/.MainSettingsActivity
adb shell service call audio 1π‘
Use of the ADB-Audioflinger teams often solve the problem of lost sound after leaving sleep more effectively than a complete reboot of the TV.
Table of frequent causes and methods of solution
So to make it easy to organize what you've learned and quickly find a solution, we've created a summary table that will help you quickly match the symptoms of a malfunction with the most likely cause and method of fixing it.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| The sound is missing in all apps. | Failure of the driver or Mute settings | Reboot TV, check the remote, reset the sound settings |
| It's sounding, but it's very quiet. | Night listening or equalizer mode | Turn off the "Night mode", reset the equalizer |
| There's no sound in HDMI only. | The Wrong Digital Format | Switch the digital format to PCM in the settings |
