Xiaomi’s modern TVs are famous for their image quality, but the built-in acoustics often fall short of the demands of true movie connoisseurs. Even flagship models like the Xiaomi Mi TV Q1 or Mi TV 6 Extreme Edition can’t physically create the immersion effect that a full surround sound system can provide, which is why connecting an external home theater or soundbar is the first step after unpacking the device.
The process of integrating the audio system into the Mi Home ecosystem may seem difficult for a beginner due to the abundance of connectors and settings, but in fact it is quite standardized. You do not need to be an engineer to achieve high-quality sound, just know the correct algorithm of actions and the features of the Android TV or PatchWall interface that are installed on your device.
In this guide, we will take a look at all the available ways of connecting, from wired to wireless, and also touch on the intricacies of setting up sound profiles. You will learn how to avoid common synchronization errors and make the most of your acoustic system, turning a regular living room into a real cinema.
Preparation of equipment and choice of interface
Before any manipulations, you need to audit your existing equipment, make sure your home theater or soundbar is in good condition and the cables are not visible damage. For Xiaomi TVs, it is critical to determine which ports are available on the back or side of the device, as the configuration of different models can vary significantly.
The best audio transmission is provided by the HDMI ARC digital interface or its more advanced version eARC. This standard allows you to transmit uncompressed multichannel sound, including Dolby Atmos and DTS:X formats, which is not available with analog connections. If your audio system supports these technologies, the choice is obvious - use HDMI.
⚠️ Note: Not all ports HDMI Xiaomi TVs support the function ARC. Look for the markings"ARC" or "eARC" next to the connector, usually HDMI 2 or HDMI 3.
In the event of absence HDMI-And if you're looking at a compatible acoustic, you can look at alternatives (S/PDIF) It is also digital and provides good quality, albeit with bandwidth restrictions for the latest codecs. 3.5 mm AUX or RCA (Tulips should be used only as a last resort, when other methods are impossible, since they do not provide surround sound.
Connection via HDMI ARC and eARC
This is the preferred method for modern systems. HDMI cable allows you to transmit video from source to TV and audio signal from TV to receiver in one line, as well as control volume from the TV remote. First connect the HDMI cable to the HDMI-labeled (ARC) port on the TV and the corresponding HDMI OUT port (TV ARC) on the soundbar or receiver.
After the physical connection, turn on both devices. Xiaomi TV should automatically recognize the connected audio system thanks to CEC (Consumer Electronics Control) technology. If this does not happen, you will need to manually activate the function in the settings menu. Usually the path is: Settings → Sound → Audio output, where you need to select HDMI ARC or Receiver.
To activate control of one remote, look in the menu section Settings → Preferences → HDMI and make sure that the CEC (or Mi Link) function is enabled. This will allow you to turn on the soundbar with the TV and adjust the volume with standard Xiaomi remote buttons, which greatly improves the comfort of operation.
☑️ Checking the settings HDMI ARC
The sound quality in this mode will be maximum. The system will determine the formats supported and choose the best codec. If you use an HDMI cable version 2.1, you will be able to transmit high-resolution sound, which is especially important for owners of expensive audio systems 7.1 and above.
Use of optical output (S/PDIF)
If your audio system is older or does not support HDMI ARC, an optical output will come to the rescue. On many Xiaomi TV models, such as the Mi TV 4S or Mi TV P1, it can be combined with a 3.5 mm connector through a special adapter-opener that comes with the kit, or output a separate Optical port.
Connect the Toslink cable between the TV and the receiver. Remember to remove the caps from the ends of the cable before installation, the light signal will not pass through the plastic plugs. Once connected to the TV menu, you must force the type of output to the Optical output or SPDIF.
An important nuance is the configuration of the digital audio format. In Settings → Sound → Digital output, you will be asked to choose a mode. For compatibility with most systems, choose PCM (for stereo) or Auto (for trying to transmit compressed surround sound). Bypass mode may not work correctly with all external decoders.
| Parameter | HDMI ARC | Optics (S/PDIF) | Bluetooth |
|---|---|---|---|
| Max. Channels. | Up to 7.1 + Atmos | Up to 5.1 (compressed) | 2.0 (Stereo) |
| Signal type | Digital. | Digital (light) | Digital (radio) |
| Volume control | From the TV remote | Depends on the model. | From the TV/Hearphone |
| Sound delay | Minimum | Minimum | Possible. |
Wireless connection via Bluetooth
Android TVs and PatchWall have a built-in Bluetooth module that allows you to connect wireless soundbars or active speakers. This method is ideal for getting rid of unnecessary wires, but has its own limitations in the quality of audio transmission. To pair, go to Settings → Remotes and accessories → Device Search.
Put your Bluetooth acoustics in pairing mode (usually by holding a power button or a special button with a Bluetooth symbol). When the TV detects the device, click on it in the list to connect. The process takes no more than 10-15 seconds with a stable signal.
⚠️ Note: Bluetooth can desynchronize audio and video streams (sound delay), which is normal for this protocol, but can be annoying when watching dynamic movies.
To minimize latency, use low latency codecs if your acoustics support them, such as aptX Low Latency. However, most Xiaomi TVs default to a standard SBC codec that provides acceptable but not perfect quality. This method is best suited for listening to music or watching news channels where lip sync accuracy is less critical.

Set up sound profiles and equalizer
Once a physical connection is successful, you need to programmatically configure the output. The Mi TV interface offers several preset profiles: Standard, Movie, Sport and User. For a home theater, the optimal choice is often the Movie or Auto mode, which dynamically adjusts the frequencies to the content.
In advanced settings (Settings → Sound → Advanced settings), you can manually adjust the equalizer. If your soundbar has its own subwoofers, it is recommended to slightly reduce the low frequencies (60-200 Hz) on the TV to avoid buzzing and "porridge" in bass, leaving this task to external acoustics.
Dolby Audio is also a feature that should be considered, if it is available in your area and supported by content (such as Netflix or Disney+), make sure that Dolby is enabled in the audio settings, which activates surround audio decoding directly on the TV before sending the signal to the receiver.
💡
If you’re watching content from your computer via HDMI, check your PC sound card settings – there should also be a output format that’s compatible with your system (e.g. 5.1 instead of stereo).
Solution: No sound or quiet sound
One of the most common problems is the lack of sound after you connect. First of all, check if the TV is in "TV Speaker Only" mode. This option sometimes turns on automatically when you switch sources. Also make sure that there is no conflict of devices in the CEC settings - try reconnecting the HDMI cable when the devices are off.
If there's a sound that's very quiet or distorted, the problem might be a mismatch of formats, like a TV trying to send a Dolby Digital 5.1 signal to a stereo system that can't decode it, and then switching the output format to a menu on a PCM would help, which converts the sound to a stereo on the side of the TV.
In rare cases, a complete reset of sound settings or even a system reboot with a 1-minute disconnect can help. Static electricity can accumulate at ports, causing disruptions to digital interfaces.
💡
90% of audio problems are solved by adjusting the output format (PCM vs Auto) and checking the cables.
