How to Make the Volume on Xiaomi TV Maximum: From Settings to Hardware Solutions

You bought a Xiaomi Mi TV, but the sound is poor? Even at maximum volume, the dialogue in the movies is barely audible and the bass is absent? The problem of weak sound is familiar to many owners of smart TVs of this brand — especially in the budget models of the Mi TV 4A, Mi TV 4S or Mi TV P1. The reasons can lie in both the software limitations and the hardware features of the built-in speakers.

In this article, we’ll look at all the ways to increase volume on a Xiaomi TV, from basic audio settings to external audio systems to even firmware modifications. You’ll learn how to bypass manufacturer limitations, what parameters affect sound quality, and what to do if speakers are physically unable to produce the desired volume level. And for Android TV 9/10 models, we’ve developed an exclusive method for activating the hidden amp through the engineering menu.

1. Basic volume settings in the Xiaomi TV menu

Before you buy external speakers or disassemble a TV, check the standard sound parameters. In most cases, the problem is solved in 2 minutes.

Open the main menu of the TV, go to Settings → Sound. Here are the key options:

• 🔊 Volume level - adjusting slider (maximum — 100, The actual volume may be limited at the level 70-80).
• 🎵 Sound mode – choose Cinema or Music to amplify low frequencies.
• 🔇 Automatic volume control – disable this feature to avoid spontaneously lowering the level.
• 🎛️ Equator – manually lift sliders on frequencies 100 Hz (bass) and 3-5 kHz).

Pay particular attention to Dynamic Compression (if your model has one), which smooths out the volume drops between quiet and loud scenes, but often works too aggressively. Try turning it off — in some cases, it adds to the mix. +15-20% volume-to-volume.

⚠️ Attention: On Xiaomi Mi models TV 4A 2018-2019 The audio menu may not have an equalizer in the year of release, and this is a hardware constraint, because the speakers in these TVs don't physically support multiband tuning.

2. Resetting sound settings to factory

If you experimented with settings or if the TV was automatically updated, the sound profiles could get lost.

1. Go to Settings → All settings → Support.
2. Select Resetting Settings → Resetting Sound.
3. Confirm the action (default password is 0000 or 1234).

After reset, check the volume on a standard test video (such as a natural YouTube video), which often solves the problem of distorted sound or a sudden drop in volume when switching channels.

Make sure the sound mode is on "Standard" | Check the volume level at 80-90% | Turn off all post-processing audio |Reboot the TV-->

3. Activation of hidden sound profiles through the engineering menu

Xiaomi Android TVs have a hidden engineering menu where you can turn on additional audio amplifiers, which works on Mi TV 4S, Mi TV P1 and later.

Instructions for entry:

1. On the remote, press sequentially: Menu → Settings → All Settings → General → Device Preferences → About → Press 5 times on Android TV OS Build
2. Return to Settings → Device – a new Engineer Mode item will appear.
3. Go to Engineer Mode → Audio → Sound Effect.
4. Activate options: 🔧 Dolby Volume Leveling – Off (Switches Off Automatic Volume Download). 🔊 Max Volume Gain - Set the value +6 dB. 🎚️ Dynamic Range Control – Low (reduces sound compression).

Important: After changing the settings in the engineering menu, the TV can automatically reset the settings when the next software update is released. To record the changes, turn off the automatic update in the Settings → System → Software Update section.

4. Connecting external audio devices

If the built-in speakers fail, the most reliable solution is to use external acoustics. Xiaomi TVs support several ways to connect:

For HDMI ARC connectivity (best option for soundbars):

1. Connect the soundbar to the HDMI ARC port on your TV (usually signed as HDMI 1 (ARC)).
2. From the TV menu, go to Settings → Sound → Digital audio output.

If after connecting the soundbar sound goes only through the TV speakers, check whether the output is turned off. HDMI Settings menu → Sound. → Audio output. Sometimes, after a software update, that parameter is reset.

5. Update firmware and fix software bugs

Weak sound can be caused by firmware errors, such as versions. MIUI TV 2.0.45 and 2.0.52 for Mi TV 4A There was a volume limiting bug that was 60 percent despite the slider being 100 percent:

How to check and update the firmware:

1. Go to Settings → System → Software Update.
2. Click Check for updates.
3. If a new version is available, download and install it (requires a stable Wi-Fi connection).

Option 2: Installation of an external amplifier
