Modern Xiaomi Mi TVs often feature built-in speakers that provide decent image quality, but do not always boast deep bass or high volume. Many users find that standard sound is not enough to watch blockbusters or listen to music in a big room, and it is at such moments that the question arises about expanding the acoustic capabilities of the device with an external audio system.
Connecting external acoustics is not just about increasing volume, but also about getting a cleaner, richer sound with detailed low frequencies. Wireless speaker allows you to get rid of unnecessary wires while maintaining the aesthetics of the interior, while wired solutions guarantee the stability of signal transmission without delay. Owners of Xiaomi TVs have several options for this task, each of which has its own technical features and nuances of setting.
In this guide, we will take a look at all the available ways to integrate external sound into your media system.We will look at both classic Bluetooth connectivity methods and more advanced options using optical and analog ports, which are often ignored by beginners. Understanding these differences will help you choose the best use case for your particular TV model.
Preparation of equipment and compatibility check
Before you start actively pairing devices, you need to make sure that your equipment is technically ready to work. Modern models of Mi TV Stick or Mi Box S may have restrictions on the number of Bluetooth devices that can be connected simultaneously, while full-fledged TV series Mi TV P1 or Q1 have more extensive functionality. It is important to study the specification of your device in advance, so as not to waste time trying to connect an unsupported audio profile.
Look at the wireless protocol versions. If your speaker is a few years old, it can use the outdated Bluetooth 3.0 standard or even earlier, while the TV requires Bluetooth 4.2 and higher for stable high-quality audio transmission. It is also worth checking the peripheral battery charge, since the search and pairing mode increases the energy consumption significantly.
💡
Make sure the speaker is in pairing mode (usually flashing the indicator) rather than just on. Many users forget to activate this mode, which makes the TV unable to see the device.
There are a few key points to consider before you start setting up:
- 🔋 Make sure the wireless speaker is charged or connected to the power supply network for stable operation.
- 📡 Check if your TV model supports a profile A2DP stereo.
- 🔌 If you plan to connect wired, make sure that the appropriate cables (optics) are available, AUX, HDMI).
- 📺 Check the back of the TV for a free port. SPDIF 3.5 mm.
You can also update your TV software to the latest version. In the Settings menu → About TV → System Update, you can check for new patches that often fix Bluetooth module errors and improve compatibility with third-party acoustics.
Configure Bluetooth connection through the system menu
The most common and convenient way to connect is to use the built-in Bluetooth module. The Android TV or PatchWall operating system interface on which Xiaomi TVs are based allows you to control the periphery in an intuitive way. First, you need to activate the search for devices on the TV itself, putting it in visibility mode for external gadgets.
Go to the settings section by selecting the gear icon in the upper right corner of the main screen. You are interested in Settings, then go to Remote and Accessories or Bluetooth. This shows the list of already paired devices and the add button. Click Add Accessory, and the TV will start scanning the surrounding space.
☑️ The algorithm of Bluetooth connection
When your speaker name appears on the screen, select the remote. The connection process usually takes a few seconds. Once paired successfully, the system will issue a notification, and the sound will automatically switch from the internal speakers to the external device. In some cases, you may need to manually change the output of the sound in additional parameters.
⚠️ Note: There may be a slight delay in audio (latency) when connected via Bluetooth, especially when watching dynamic scenes or playing video games, when the sound is behind the image by a fraction of a second.
If you can’t connect, try removing the device from the forgotten list on your TV and repeat the procedure again. Also make sure that the speaker is not connected to your smartphone at this point, as many models do not support multipoint (simultaneous connection to two sources).
Using SPDIF optical output for high-quality sound
For audio systems that require high-quality, non-compression transmission, the SPDIF (Toslink) optical output is ideal, which allows multi-channel audio transmission, which is especially true for home theaters and soundbars that support formats like Dolby Digital. Unlike Bluetooth, it eliminates signal loss and delay.
On the back of Xiaomi TVs, there is often a port signed as SPDIF or Optical. You will need a special fiber optic cable to connect. One end of the cable is inserted into the TV socket before the characteristic click, and the other into the corresponding input on the speaker or receiver. It is important not to bend the cable at an acute angle, since there is a fragile fiberglass inside.
After the physical connection, you need to set the output programmatically. Go to Settings → Sound. Find Digital Output or S/PDIF and select On. You may also need to change the format to Pass-through if your speaker system is able to decode audio formats itself.
| Parameter | Bluetooth | Optical (SPDIF) | HDMI ARC |
|---|---|---|---|
| Sound quality | Medium (compression) | High (no loss) | Maximum. |
| Delay (Latency) | Got it (noticeable) | Absent. | Minimum |
| Volume control | From the TV remote | Often from the remote speaker | From the TV remote |
| Support for formats | SBC, AAC | Dolby Digital, PCM | Dolby Atmos, DTS |
Using an optical cable ensures stable operation without interference from Wi-Fi routers or microwave ovens, which can wirelessly signal. This is the most reliable option for stationary setups, where sound quality is paramount.
Connection via HDMI ARC and eARC ports
HDMI ARC (Audio Return Channel) technology allows audio from a TV to external acoustics to be transmitted over the same cable that transmits the image. This eliminates the need for a separate optical or analog cable. If your wireless speaker is part of a soundbar or HDMI-enabled home theater, this is the best choice.
Find an HDMI connector marked with the ARC or eARC logo on the back of your TV. Usually, there is one such port, most often HDMI 1 or HDMI 2. Connect the HDMI cable from that port to the appropriate input on the speaker system. Once the devices are turned on, the TV must automatically identify the new audio system and switch the output.
What is the difference between ARC and eARC?
In the TV sound settings, make sure that the output device is external speakers or receiver (HDMI).The HDMI CEC function must be activated so that the TV remote can control the volume of the connected speaker. On Xiaomi TVs, this feature is often called Mi Remote or simply CEC in the general settings menu.
The advantage of this method is that it can take full advantage of surround sound, if the content and hardware support it, and when you turn off the TV, the connected acoustics will automatically turn off, which adds comfort to daily use.
Analog connection via 3.5 mm connector
Not all wireless speakers are wired-free. Many models, such as the JBL, Sony or Xiaomi Mi Portable Bluetooth Speaker, have an AUX input (3.5 mm), which allows them to be used as normal wired speakers, connecting directly to the TV, as long as it has the appropriate Headphone/Audio Out output.
The connection requires a 3.5mm jack-to-jack cable, one end inserted into the headphone socket on the TV, the other end into the AUX input on the speaker, and once connected, the sound may not appear automatically, you need to go to the audio settings and select External speakers or change the output type to Audio output.
⚠️ Note: When connected via a 3.5mm analog connector, volume control can be de-synchronized. You will have to adjust the sound level separately on the TV remote and with the buttons on the speaker itself to achieve optimal balance.
This is a good way to be versatile and have no delays, but the sound quality will be limited by the digital-to-analog converter (DAC) of a TV, which may not be suitable for high-resolution music, but it is acceptable for news programs and regular TV.
💡
Analog connection is a “plan B” that will help if Bluetooth is unstable and there is no optical output on the TV.
Solving problems with connection and sound delay
Even with the right setup, users can run into problems. One of the most common is de-synchronization of audio and video. If actors' lips are not moving in the beat of their voice, try changing the audio format settings in the TV menu. Switching from Auto to PCM often eliminates lags when using Bluetooth headsets and speakers.
If the TV can't see the speaker, try rebooting both devices, sometimes forgetting the device in the Bluetooth menu and re-pairing it, and also make sure there are no thick walls or working microwaves between the speaker and the TV that can jam the signal.
If you have a sound, but it's very quiet, check the equalizer settings. Some Mi TVs have presets like "Film," "Music," "News." Choosing a "Music" or "Standard" mode can increase the power output.
