Xiaomi’s Android TV and PatchWall TVs often have the problem of spontaneously turning on audio programs, the background soundtracks that overlap the main content, which can occur when watching digital TV (DVB-T2), connecting via HDMI ARC, or even using streaming services. In most cases, the fault of the Live TV system application or the built-in audio decoder that automatically switches the audio channels is to blame.
In this article, we’ll look at all the ways you can disable audio on Xiaomi Mi TV 4/4A/4S/5, Redmi Smart TV and other models, from simple menu settings to deep changes in system files. We’ll focus on when standard methods don’t work, and we’ll also look at hidden commands for the engineering menu that aren’t documented in the official instructions. If your TV sends a message “Audio program changed” or the sound disappears when you switch channels, you’re on the right track.
Why does Xiaomi TV include audio?
The problem with automatically switching audio paths is typical for Xiaomi TVs on Android TV 9/10/11.
- 🔄 Conflict of the built-in Live app TV It's using external sources of signal (satellite receivers, set-top boxes) and it's trying to "improve" the sound, but it's resetting the settings instead.
- 📡 Unstable signal DVB-T2: at a weak signal level, the TV can switch to a backup audio track (for example, with a AC3 on MP2).
- 🔌 Problems with HDMI ARC/eARC: If the TV is connected to a sound bar or receiver, it may receive false commands about changing the audio stream.
- 🤖 Firmware errors: in versions MIUI TV below 3.0.12 was a bug that caused the com.droidlogic.tvplayer system app to reset audio settings.
According to service centers, the most common problem occurs on the models Mi TV 4A 32"/43 " (2018-2020) and Redmi Smart TV X50/X65 (2021). Owners complain that after updating the firmware, the sound begins to "jump" between tracks, and in the settings appears a notification "Audio Program: Russian (Dolby)", although the user chose a different language.
Method 1: Disabling the audio program through standard settings
Let's start with the simplest method, which works 80 percent of the time, and it's suitable for TVs with MIUI TV 2.0 firmware and later.

- Go to the section Sound → Additional settings → Audio program.
- Select Turn off Auto Switch (or Manual Mode in older versions).
- Save the changes and restart the TV (Settings → About TV → Reboot).
If there is no such item, try an alternative path:
- When watching TV, press the button. OK remote → Choose the audio icon (dynamics).
- In the menu that opens, find the audio program line and set the value Off. or Main.

Important: On some models (Mi) TV 4S 55”) after the audio program is turned off, the sound may disappear on the HDMI-In this case, resetting the sound settings will help:
Settings → Sound → Reset sound parameters → ConfirmMethod 2: Reset the Live TV app (for digital TV)
If the problem only occurs when watching DVB-T2 or satellite TV, the Live TV system app is to blame.

Method 3: Disconnect via the Engineering Menu (for advanced)
If standard methods don’t work, you can use a hidden engineering menu, which is suitable for Android TV 9/10 models and requires caution – incorrect changes can lead to system failure.
Instructions:
- Turn on the TV and open the standard remote (not a game!).
- Consistently press the buttons: Menu → Up → Up → Down → Down → Down → Left → Right → Right → OK (Contra code for Xiaomi).
- Factory Mode will open. Go to Audio Settings.
- Find options: Auto Audio Switch → Install Disable HDMI ARC Audio Control → Install Off DTV Audio Mode → Select Manual
Save & Exit
💡
If the engineering menu doesn’t open, try using the Mi Box remote – some Xiaomi TV models recognize it as “service.”
Warning: There are options on the engineering menu that affect Wi-Fi, Bluetooth, and even the display array. Don't change anything except the above.
| Parameter in the engineering menu | Recommended value | Consequences of improper setting |
|---|---|---|
| Auto Audio Switch | Disable | Continuously shutting down sound on all sources |
| HDMI ARC Audio Control | Off | Inability to transmit sound to the sound panel |
| DTV Audio Mode | Manual | Sound distortion at a weak DVB-T2 signal |
| SPDIF Output | PCM (if you use optical output) | No sound on the AV-receiver |
Method 4: Update the firmware or roll back the version
In some cases, the audio program is caused by a firmware bug, such as MIUI TV 3.0.8 (2022) which caused the TV to ignore manual audio settings, and the decision to upgrade or roll back:
- 🔄 Update: Go to Settings → On TV. → Update the system. If a new version is available, install it. After the update, reset the audio settings.
Recoil (if the problem has occurred after the update):
- Download the old firmware from the official Xiaomi website (select your model).
- Copy the file. update.zip on USB-storage device FAT32).
- Connect the flash drive to the TV and update manually (Settings → About TV → Update via USB).
Critical information: The firmware rollback is only possible within a single major version (e.g., from 3.0.12 to 3.0.5). Trying to install firmware older than the one on the TV out of the box will result in the bootloader being blocked.
💡
Before rolling back the firmware, check the compatibility of the version with your TV model. Wrong firmware can bring the device down!
Method 5: Radical solution – disabling system applications via ADB
If none of these methods work, the last thing that we can do is to shut down the system applications that control sound.
- The computer is equipped with ADB (Android Debug Bridge).
- Developer mode on the TV (Settings → About TV → Software version – press 7 times on the line with the version).
- USB-cable (or Wi-Fi connection via cable) ADB over Network).
⚠️ Attention: After completing these commands, Live app TV It will stop working, and some audio functions (e.g., equalizer setting) may become unavailable:
adb shell pm enable com.droidlogic.tvplayerWhat if the audio is lost after the audio program is turned off?
In rare cases, after manipulating the audio settings, the TV may stop playing sound at all.
- Check physical connections: Disconnect and reconnect HDMI-cables, if you use them. HDMI ARC, Try connecting the speakers directly through the optical output. Make sure the headphones are not connected to the 3.5mm connector.
Reset the sound settings:
Settings → Sound → Additional settings → Sound resetCheck the sound output mode:
Settings → Sound → Sound Mode → Install Stereo (not “Auto”)Update the audio drivers:
- Go to Settings → About TV → Update drivers.
- If there is no partition, do a complete reset of the TV.
If the problem persists, reset the settings of the app that broadcasts (e.g. YouTube or Netflix).
