Customizing the sound on the Xiaomi TV: from basic parameters to advanced features

Xiaomi TVs are known not only for bright screens, but also for flexible audio settings that allow you to adapt the audio to any viewing conditions. HDMI ARC, Imbalance between high and low frequencies or sudden loss of sound after a firmware update. This article will help you understand all the nuances of the configuration, from the basic parameters of the equalizer to solving specific malfunctions.

We will not only look at the standard options in the Mi menu. TV, But also hidden features available through the engineering menu, and also give recommendations for optimizing sound for different scenarios: movies, music, games and sports broadcasts. TV A Pro, Mi TV Q2 Redmi Smart TV X, where sound processing algorithms differ from budget TV shows.

If you're connecting external acoustics -- soundbar, home theater, headphones -- you'll find step-by-step instructions for synchronizing devices and eliminating sound delays. And for those of you who like to experiment, we'll reveal the secrets of fine tuning through the Internet. ADB-teams and third-party applications.

Basic sound settings in the Xiaomi menu TV

So let's start with the basics: where to find the audio settings and how to set them up correctly, depending on the firmware version. MIUI TV The location of the menu items may vary slightly, but the general logic is maintained:

Settings → Sound → Sound modes

Pre-configured profiles are available here:

• 🎬 Standard – Balanced sound for everyday viewing.
• 🎵 Music – High and medium frequencies are enhanced for better detail.
• 🎮 Games – focus on low frequencies for explosion effects and steps.
• 🏟️ Sports – increased volume of commentators and tribunes.
• 🎥 Cinema – Extended Dynamic Range for Film Sounding.

To manually adjust, select Custom - you can adjust the equalizer (60 Hz to 16 kHz), the balance between the left/right speaker and the volume level relative to other sources. Note: on models with Dolby Atmos support (for example, Xiaomi). TV 6 OLED) In this menu will appear an additional switch to enable surround sound.

The important thing is that you have connected the TV to AV-receiver or soundbar through HDMI ARC/eARC, Some settings in the Xiaomi menu can be blocked, in which case the audio control is transferred to the external device, and you need to adjust the settings on it.

💡

If the sound becomes too quiet after selecting Movie mode, check the volume normalization settings in the same menu, and disabling this option will return the original volume of the content.

Volume problems: Why the sound is too quiet or loud

One of the most common complaints of Xiaomi users TV — The problem is that there's a volume discrepancy between different sources, like Netflix is loud and YouTube is barely audible, and the reason is because the manufacturer automatically normalizes the device by default.

To turn it off:

Settings → Sound → Additional settings → Normalization of volume

Once you disable this option, you’ll get the original volume of content without artificial alignment, but be prepared to manually adjust the level when switching between apps. TV 11+ (for example, Xiaomi TV S Pro) normalization works more intelligently by analyzing audio track metadata.

Another common problem is the quiet sound when connected via HDMI. This is due to the signal level restriction in the protocol. HDMI-CEC. Decisions:

• 🔊 Check the sound settings on the connected device (set-top box, game console).
• 🔄 Reconnect the cable by selecting from the menu HDMI-portage PCM auto.
• 🛠️ Update the TV firmware - in new versions, bugs with audio transmission have been fixed.

⚠️ Warning: If after updating the firmware sound is completely lost, reset the sound settings through the engineering menu. → 4725 → Audio → Reset.

Equalizer setting: how to improve sound

Built-in equalizer in Xiaomi TV This allows you to spot-correct the frequency response of the sound, which is especially useful if your TV is in a large room with an echo or, conversely, in a small room with excessive audio absorption.

Recommended settings for different scenarios:

To access advanced equalizer settings on Android models TV 10+ Use the Equalizer app FX (available on Google Play for TV). It allows you to save several presets and quickly switch between them.

If after setting up the equalizer there were distortions (wheezing, crackling), reduce the gain at frequencies below 150 Hz - the dynamics of budget Xiaomi models are not designed for deep bass.

Connecting external acoustics: soundbar, headphones, home theater

Xiaomi TVs support several ways to connect external audio devices, and the choice of method depends on your tasks:

• 🎧 Bluetooth headphones: minimum latency (from 60 ms), but problems with synchronizing sound and video are possible.
• 🔊 HDMI ARC/eARC: Best quality for soundbars (supported by Dolby Digital)+ and DTS:X).
• 🎛️ Optical output (S/PDIF): stable signal without compression, but without feedback.
• 🔌 3.5 mm jack: universally but limited to analog signal.

To connect via HDMI ARC:

1. Connect the cable to the port marked ARC on TV and soundbar.
2. From the TV menu, select: Settings → HDMI-CEC → Turn on
3. Set up a soundbar mode HDMI IN.
4. In the TV sound settings, select Exit through HDMI ARC.

⚠️ Note: When connected via Bluetooth, the audio delay (lip sync) can reach 200 ms. To reduce it, in the settings of the TV, turn on the option Low audio delay (available on Android models). TV 11+).

For Xiaomi models TV A2 And now, the automatic switching feature is available, where the TV itself determines when to transmit audio to an external device (for example, when you turn on the soundbar) to activate it:

Settings → Sound → Auto-Switching of Audio Devices

Sound Problem Solving: No Sound, Echo, Delays

If the sound is lost or distorted, follow the algorithm:

1. Check physical connections: Push the cables, make sure the headphones are charged.
2. Restart the TV: Hold the power button on the remote for 5 seconds.
3. Reset the sound settings via the engineering menu (Menu) → 4725 → Audio → Reset).
4. Update the firmware: in Settings → On TV. → Updating the system.

Frequent problems and their causes:

To diagnose sound problems in Xiaomi TV There's a hidden function called a speaker test to run it:

Settings → Support → Diagnostics → Sound test

The TV will play the signals on each speaker in turn, and if a channel is not working, it indicates a hardware malfunction.

💡

If after all the manipulations, the sound does not appear, check if the speakers in the engineering menu are turned off. → 1147 and find Speaker Enable.

Advanced settings: engineering menu and ADB-team

For experienced users willing to experiment with Xiaomi TV The hidden settings are available through the engineering menu and ADB. These methods allow:

• 🔧 Change the volume limit (remove the limit of 100%).
• 🎛️ Set up sound processing at the firmware level.
• 🔄 Insert experimental codecs (e.g, LDAC Bluetooth).

To get into the engineering menu:

1. On the remote, press Menu.
2. Enter the code 4725 (for new models) or 1147 (for older models).
3. Go to the Audio section.

Here you will find options that are not in the standard menu:

• Max Volume Limit – Removes the software volume limit.
• Dolby Audio Processing – Includes/disables Dolby Processing.
• HDMI Audio Format – a forced choice of format (PCM, Dolby, DTS).

⚠️ Warning: Changing the parameters in the engineering menu can lead to unstable operation of the TV. Do not change the values of parameters with unknown names - this can cause a firmware failure.

For even more in-depth adjustment, use ADB (Android Debug Bridge. Connect your TV to your PC and execute commands:

adb shell settings put global audio_offload_min_duration_ms 5000


adb shell settings put global force_disable_audio_effects 1

The first command reduces the latency of sound when played over Bluetooth, the second - disables system effects that can distort the sound.

Optimizing sound for different scenarios

The audio settings should adapt to the content, and here are the recommendations for popular scripts:

🎬 Cinema and TV series:

• Turn on the Movie mode in the sound settings.
• Activate Dolby Atmos if your TV and content support it.
• Set the sound delay (AV Sync on +50 ms to compensate for video processing.

🎮 Games:
