How to add the sound of the conversational speaker Xiaomi: from adjustment to firmware

You bought a speaker, soundbar or a Xiaomi TV, but the sound seems too quiet? Conversational frequencies (voice announcer, podcasts, dialogue in movies) are lost against the background of music or bass? The problem is familiar to many owners of the brand’s technology – especially when it comes to budget models like Mi. TV 4A Mi Portable Bluetooth Speaker: 80% of the time, you can fix it without repair using hidden settings or software tricks.

In this article, we will discuss all the working ways to increase the volume of a conversational speaker, from basic equalizer adjustments to flashing the device. Note: the methods are different for Xiaomi TVs, portable speakers and soundbars. We've noted which instructions are suitable for each type of technology, and you'll also find a table of compatibility of models and models. FAQ answering frequent questions (for example, why the sound is quieter after the update).

Warning: Some methods require disabling protection MIUI If you're not sure about your skills, skip those sections and go to the service center. For most users, the first three ways are enough.

1. Check basic settings: volume, sound mode and equalizer

Start with the obvious: maybe the problem isn't the hardware, but the wrong settings. On Xiaomi TVs and soundbars, check out:

• 🔊 Volume level in system settings (sometimes limited to the level of the system) 70-80% hearing-protection).
• 🎵 Sound mode: choose Music or Movie over Speech – paradoxically, the latter often cuts high frequencies.
• 📊 Equator: Raise the sliders to 2-4 kHz (the range of human voice) and reduce bass (60-250 Hz).

On Xiaomi portable speakers (e.g. Mi Portable Bluetooth Speaker) 16W) There is no equalizer, but it is possible:

• 🔋 Check battery power – at levels below 20%, many models automatically turn down the volume.
• 📱 Update the firmware through the Mi Home app (instructions in section 4).
• 🔌 Connect the column to the socket (if supported) – this removes power restrictions.

If the sound remains quiet after this manipulation, move to the next section. TV Q1E) Settings menu → Sound. → Also hidden is the volume normalization option – turn it off to remove automatic level alignment.

2. Engineering menu: hidden settings of sound amplification

In Android devices TV (All modern Xiaomi TVs and some soundbars have an engineering menu where you can manually increase the volume of the speaker. This method only works for models on Amlogic processors (for example, Mi Mi). TV 4S, Mi TV A2).

To get into the engineering menu:

1. Open the bootloader app (if not, install it from Google Play).
2. Enter the code in the address bar: file:///sys/class/amhdmitx/amhdmitx0/attr
3. Press Go and the list of parameters will open.
4. Find a line. spk_gain and change the meaning of c 0 on 6 (maximum).
5. Save the changes and restart the TV.

For Xiaomi soundbars (such as Mi Soundbar 3.1), the path is different:

• Connect the soundbar to the PC by USB-C (You need a cable that supports data transmission).
• Open Device Manager on Windows and find Mi Soundbar in the Sound Devices section.
• Right-click. → Properties → Additionally. → increase the magnification to +10 dB.

⚠️ Attention: Don't enlarge spk_gain higher 6 — This can cause sound distortion or overheating of speakers on models with small speakers (e.g. Mi). TV 4A 32") maximum-safety — 4.

3.Apps for amplifying sound: Equalizer APK and Viper4Android

If your device is running on Android TV (All Xiaomi TVs after 2018, you can install third-party apps to fine tune the sound:

• 🎛️ Equalizer APK — Simple 10-band equalizer with pre-speech presets.
• 🐍 Viper4Android — Advanced audio processor with compressor and amplifier (requires root rights).
• 🔊 SoundAssistant – allows you to disable volume restrictions at the system level.

Instructions for Equalizer installation APK:

Download. APK site [apkmirror.com](https://apkmirror.com) (Android TV)

Transfer the file to the flash drive and connect it to the TV

In the settings of the TV, turn on Unknown sources (Settings) → Annexes → Special access)

Install. APK File Manager (for example, File Commander)

Run Equalizer and select Voice Boost Preserve-->

For Viper4Android need:

1. Get root rights (instructions for Xiaomi) TV section 5).
2. Install Magisk Module for the Viper4Android.
3. In the application settings, enable: Driver: Legacy Mode Effect: Convolver (import) IR-Speech filter - Master Limiter: -3 dB

⚠️ Attention: Apps like Viper4Android If after installation there are wheezing or the sound is completely gone, remove the module through Magisk Manager and reset the settings.

4. firmware update: why older versions "cut" sound

Xiaomi’s firmware had a bug until 2021: the automatic volume normalization algorithm cut the high frequencies (including voice) too aggressively.

• Mi TVs TV 4A/4S firmware MIUI TV 2.0.60.
• Soundbar Mi Soundbar first generation (until 2020).
• Mi Bluetooth Speaker without Mi Home support

To update the firmware:

For TVs:

1. Go to Settings → About TV → System Update.
2. If there are no updates, download the latest version from the official website (select your model).
3. Move the file. update.zip flash drive (format) FAT32) And plug her into the TV.
4. In the update menu, select Local Update and specify the file.

For soundbars and columns:

1. Install the Mi Home app on your smartphone.
2. Connect the device to the same Wi-Fi network as the phone.
3. In the device card in Mi Home, click ⚙️ → Firmware update.

💡

If after updating the sound became even quieter, reset the settings to factory (Settings) → This will remove the equalizer user profiles that may have conflicted with the new firmware.

5. firmware of custom Recovery and modified software

If all previous methods failed, the last option is custom firmware installation, which removes all software volume restrictions, but it is not warranty and can lead to unstable operation, suitable only for power users!

For Xiaomi TVs on Amlogic processors (most models), the procedure is:

1. Unlock the bootloader through the official Xiaomi website (you need a Mi Account and device binding).
2. Install. TWRP Recovery for your model (see the instructions on the forum) 4PDA).
3. Download modified firmware with sound normalization disabled (for example, MIUI TV Pro).
4. Flush it through. TWRP, Preliminary backup of the original firmware.

For soundbars and columns, custom firmware is rare, but you can try:

• 🔧 Reflash the amplifier chip (a soldering iron and a programmer are required).
• 🔄 Replace the speakers with more sensitive ones (for example, with impedance of 4 ohms instead of 8 ohms).

⚠️ Note: On Xiaomi TVs with MediaTek processors (e.g. Mi) TV Q1E) Unlocking the bootloader can lead to the blocking of Netflix and Disney+ due to Widevine breach L1. Before firmware, check the processor model in Settings → On TV. → Model.

💡

Castom firmware gives you maximum volume, but it takes away official support. Use this method only if you are ready for possible bugs and absences. OTA-update.

Hardware solutions: amplifiers and external speakers

If the software methods didn't work, there's hardware amplification.

• 🔊 External amplifiers (e.g. Fosi Audio) BT20A) — Connects between the TV and the soundbar.
• 🎧 Active columns with optical input (e.g. Edifier) R1280T).
• 📡 Bluetooth transmitter (if the TV has a weak built-in module).

To connect the external amplifier:

1. Buy an amplifier with an entrance RCA 3.5 mm (depending on the output of your TV).
2. Connect the TV to the amplifier with a cable AUX-AUX or RCA-RCA.
3. Set the TV output to external speakers (Settings) → Sound. → Exit).
4. Adjust the volume on the amplifier - this will make the most of the conversational speaker.

If the budget is limited, you can use a passive resistor attenuator (worth it). ~It connects between the TV and the soundbar and tricks the system into giving a bigger signal:

TV (3.5 mm) → Attenuator (10 kΩ) → Soundbar (RCA)

💡

When buying an amplifier, pay attention to impedance: it must match the impedance of your speakers (usually 4 or 8 ohms), Failure to follow this rule leads to overheating and distortion.

7. fault diagnosis: when it's time to go to service

If none of these methods worked, it could be the hardware failure.

• 🔇 The sound is quiet even at maximum, but the bass is heard normally (twitter damaged - high-frequency speaker).
• 🔊 Wheezing or distortion at volume above 50% (amplifier faulty).
• 🔌 The sound is lost when connected to a certain source (problem with the connector). HDMI ARC optical).

The most frequent breakdowns:

Before the service visit:

• 📋 Write down the serial number of the device (located on the sticker at the back).
• 🎥 Shoot a video demonstrating the problem (this will help the master to diagnose the breakdown faster).
• 🔧 Check if the service center has original parts for your model.
