Portable speakers often wonder how to use their devices not only with smartphones, but also in conjunction with a personal computer. Xiaomi offers a wide range of Bluetooth speakers that can be a great addition to a multimedia PC system. However, standard wireless connection does not always provide the necessary sound quality or stability of the connection, especially in the conditions of noisy air.
Use of a wired connection through USB-The port seems like a logical solution for a lossless digital signal, and many users mistakenly believe that it is enough to simply connect devices with a cable to get a high-quality digital signal. DAC (In practice, the situation is more complicated, since most portable models of the Mi Portable Bluetooth Speaker or Xiaomi Sound are designed primarily as wireless receivers.
In this guide, we will discuss the technical details of connecting Xiaomi acoustic systems to a computer, you will learn which models support audio transmission over the wire, how to circumvent the limitations of the Windows operating system and what alternative methods will provide the best sound. USB-The port on many Xiaomi speakers is used solely for charging the built-in battery and does not support the transmission of audio stream.
Technical limitations USB-connection
Before looking for a cable, you need to be clear about the architecture of the device.Most budget and mid-budget Xiaomi models, such as the Mi Compact Bluetooth Speaker 2, are equipped with a micro USB port or USB Type-C. However, having a physical connector does not guarantee its functional versatility (5V/1A).
If your model doesn't support USB Audio Class, your computer won't see it as an external audio device, instead, it may have unknown hardware or battery charging in the device manager, because there's no controller inside the speaker to process the digital signal that's coming through the wires.
⚠️ Warning: Attempting to apply a voltage above 5 volts to the column's power input can cause permanent damage to the charge controller and the device to fail.
To check for support, you need to check the specifications of a particular model on the official website or in the instructions. If there is no USB DAC in the list of supported protocols, then direct connection to transmit sound is impossible, in which case the port performs only an energy function.
Verification of compatibility and operating modes
You can program your device to connect it to your PC. Even if the driver doesn't automatically install, the system can zareagirovat' to connect new hardware. Go to the Windows Sound Control Panel to check the list of playback devices.
Some advanced models, such as the Xiaomi Mi Bluetooth Speaker Square or larger stationary versions, may have hidden modes of operation.Switching between them is often done by a combination of buttons on the body.For example, prolonged holding of the power button or double pressing the track switch button can activate Line-in or USB Audio mode.
- 🔍 Connect the column to the PC and open Device Manager in Windows.
- 🔍 Check the Sound, Gaming and Video Devices section for new entries.
- 🔍 Note the charge indicator: if it burns but there is no sound, it is likely that the data mode is not activated.
If the system recognizes the device as a “Memory” or “Charge”, but not as a speaker, then the software part of the column is not designed to receive audio stream via USB. In this case, you should not waste time installing third-party drivers - the hardware does not support this function.

Alternative: Use AUX-cable
The most reliable way to connect Xiaomi speakers to your computer while maintaining high sound quality is to use 3.5mm AUX analog input. Many models, including the Mi Bluetooth Speaker (older versions) and Xiaomi Sound Bar, feature a combined connector or separate cable input.
To implement this method, you will need a cable type 3.5 mm Jack - 3.5 mm Jack. One end connects to the output of the headphones on the motherboard or computer sound card, and the other - to the speaker, in which case the speaker operates in passive amplifier mode, receiving the already ready analog signal.
| Type of connection | Sound quality | Stability | Delay (Latency) |
|---|---|---|---|
| Bluetooth (SBC) | Average. | Low. | Tall. |
| Bluetooth (aptX) | High. | Medium | Medium |
| AUX Cable | Depends on the DAC PC | Tall. | Absent. |
| USB Audio (if any) | Maximum. | Tall. | Minimum |
The advantage of analog is that there is no signal compression that is typical of Bluetooth codecs. However, the quality of the final sound will depend directly on the quality of the built-in sound card of your computer. If the PC is a cheap integrated codec, a noticeable improvement over Bluetooth aptX HD may not occur.
💡
Use the shielded AUX-cable not exceeding 1.5 meters in length to minimize tips and background noises during analog connection.
Connection via an external USB Bluetooth adapter
If the Bluetooth module built into the computer is unstable or absent, the best solution is to buy an external one. USB-This device is connected to a free port. USB 2.0 or 3.0 and allows you to create a stable wireless connection with the Xiaomi speaker.
Modern adapters that support Bluetooth 5.0 and higher provide significantly better range and bandwidth. For audiophile modes, it is important that the adapter supports aptX, aptX HD or LDAC codecs, if your speaker can do them. Otherwise, the sound will compress into the basic SBC format.
The setup process is usually automatic: Windows 10 and 11 independently find and install drivers for most popular chipsets (Realtek, CSR, Broadcom). After installing the drivers, you need to go to Bluetooth settings, select your Xiaomi column from the list of available devices and pair.
⚠️ Note: Do not connect Bluetooth adapter to ports USB 3.0, located next to the working drives or external hard drives.This can cause interference of signals 2.4 GHz and cause interruption of sound.
☑️ Checking Bluetooth connection
Customization of sound in the operating system
After a successful physical or wireless connection, it is important to properly configure the audio output settings in the operating system. Go to the sound control panel, find your playback device and open its Properties.
The "Additional" tab allows you to select bit rate and sampling rate. For most scenarios, the optimal choice would be 24 bits, 48000 Hz (Studio Recording). Set too high values on cheap devices can lead to distortion or no sound.
It is also recommended to disable all audio "improvements" such as virtual surround sound or equalizers if you want to hear the original signal. In some cases, activating the Disable all enhancements feature eliminates cracking and delays.
Control Panel -> Sound -> Playback -> Device Properties -> Additional -> Default formatRemember to update your sound card and Bluetooth adapter drivers through your device manager or manufacturer’s website. Outdated software often causes conflicts and unstable multimedia devices.
💡
Properly adjusting the sampling rate in Windows can improve the purity of sound and eliminate wheezing when playing music.
Addressing common problems
A common problem is that you spontaneously shut down the speaker after a certain downtime, and this is a power saving mechanism built into the device's firmware, and to avoid this, some users plug the speaker into a power source while they're working on a PC.
If the sound is interrupted or an echo appears, try turning off the microphone in the Windows audio settings, as the system may try to use the built-in speaker microphone to record, creating a feedback loop.
If your computer "sees" a speaker but there's no sound, check the volume level in the mixer. Sometimes Windows assigns a low volume to newly connected devices by default. Make sure the device is selected as the Device by default.
- 🔧 Reboot Bluetooth services on Windows via services.msc.
- 🔧 Remove the device from the list of coupled and perform again.
- 🔧 Check the speaker on another device (smartphone) to rule out the breakdown of the acoustics.
