How to switch speaker on Xiaomi phone: the complete guide

Owning a modern Xiaomi smartphone involves not only calls, but also multimedia content consumption, where sound quality plays a crucial role. Users often face the need to quickly change the source of playback: for example, switch audio from an internal speaker to a wireless headset or external speaker system. In the MIUI or HyperOS operating system, this process may not be obvious due to the deep customization of the interface.

There are several ways to control audio flow, depending on the type of connection and device model, which can be manually set up via the Bluetooth menu, automatically switching when connecting a cable, or using special features to create a stereo pair, understanding these mechanisms allows you to flexibly control the sound scene in any situation.

In this article, we’ll break down all the available methods for switching speakers, including hidden settings and engineering menus. You’ll learn to solve problems when sound doesn’t go to the right device, and you’ll be able to customize the perfect playback for games, music or movies. It’s important to know that some Redmi and POCO models lack hardware stereo, and software-based bass expansion may be the only way to improve quality.

Basic methods of switching audio output

The easiest and most obvious way to switch audio is to physically connect an external device. When you plug a headphone plug into a 3.5mm connector or plug a USB-C adapter in, Android automatically redirects the audio stream. However, there are nuances in Xiaomi's settings that allow you to control this process more subtlely.

If automatic switching does not occur, you need to check the status of the connected devices in the settings menu. Often the system can get stuck on the previous source, especially if the Bluetooth headset was previously connected and is in range, in which case manual intervention of the user is required.

To force the choice of the audio output device, perform the following actions:

• 🎧 Open Settings and go to the Bluetooth section.
• 🔊 Find your headset or column in the list of available devices.
• ⚙️ Click on the gear icon or arrow next to the device name.
• 🔄 Make sure the media audio switch is activated.

⚠️ Warning: If the audio continues to come from the speaker after the headphones are connected, try playing any audio file. Sometimes the system only activates the external output after the audio signal appears.

In some cases, especially when using the adapter USB-C 3.5 mm from third-party manufacturers, it may be necessary to activate the mode OTG. Without it, the smartphone will not power the DAC headphones, and the switch will not happen"OTG".

Set up Bluetooth devices and stereo pairs

Wireless connectivity provides more room for maneuver, but requires proper initial setup. Xiaomi smartphones support A2DP profiles to transmit quality stereo sound. To switch the speaker to a Bluetooth device, it must be paired and labeled as media preferred.

A unique feature for owners of two identical Mi True Wireless headphones or Mi Smart Speaker speakers is the ability to create a stereo pair. This allows you to divide channels (left and right) between two devices, creating surround sound. In mono mode, the sound is duplicated on both speakers, which is convenient for parties.

The process of creating a stereo pair for Mi Smart Speaker speakers is as follows:

• 📡 Make sure that both speakers are connected to the same Wi-Fi network.
• 📱 Open the Mi Home app and select one of the columns.
• 🔗 Click on three dots in the corner and select Stereopara.
• ✅ Follow the instructions on the screen to synchronize channels.

When using a regular Bluetooth headphone, it is important to keep a volume balance, sometimes after switching from speaker to headphones, the sound level remains low, in which case you need to separately increase the volume of the media at the time of playback, since MIUI stores separate volume profiles for different types of output.

Use of the "Mono-audio" mode and special features

The mono-audio feature is primarily designed for people with hearing impairments, but it can also be useful in use cases: When activated, the stereo signal is mixed into a single channel, allowing you to hear all the sounds even if only one earpiece is connected or if you switch to a mono speaker.

To activate this feature, go to Settings → Advanced Settings → Special. features → Hearing. Here you will find the Mono-audio switch. Enabling this option forcibly changes the way the system processes the sound stream before it is sent to the speaker.

The same menu also has a left-right balance, so you can shift the sound scene completely to one side, for example, if you have a damaged left speaker or earphone, you can program all the sound to the right channel without losing information.

💡

Use the channel balance to compensate for the asymmetrical location of the smartphone in your pocket or bag if one of the speakers is covered by a cloth.

It's worth noting that the mono mode can change the way you hear sound in games and movies, where the spatial location of the sound sources is important, and the panning disappears, and all the effects start to sound "from the center." This is rarely critical for ordinary music listening.

Creating a wireless stereo system from two phones

Owners of the Xiaomi ecosystem can combine two smartphones to play audio, and while this is difficult to do with regular means, there are scenarios for using translation apps or Mi Share for media transmission, but a more reliable way is to use third-party synchronization apps.

Apps like SoundSeeder or AmpMe can turn multiple Android devices into a single sound system, one phone as a server (music source), and others (clients) play the sound synchronously, which is a great way to party when the power of a single Redmi or POCO speaker is not enough.

To configure such a system, it is necessary:

• 📲 Install the selected application on all participating phones.
• 📶 Connect all devices to one Wi-Fi network.
• 🎵 Run the application on the main device and select the track.
• 🔗 Connect the rest of the phones through QR-code.

⚠️ Note: There may be a slight latency when using third-party audio synchronization apps. This can be critical for watching videos, so use this method primarily for music.

The quality of communication in such a system depends on the speed of your router. If the network is congested, sound may be interrupted or out of sync between devices. It is recommended to use the 5 GHz band to ensure a stable data flow.

Customization of equalizer and sound effects MIUI

Switching speakers is not just about choosing a device, but also setting up the sound. Xiaomi smartphones have a powerful audio engine built in, often developed in collaboration with Dirac or Harman Kardon (in flagship models). These settings are accessed in the Settings menu → Sound and vibration → Sound quality and effects.

You can choose between different music genres or manually adjust frequencies. Equalizer settings can be changed globally, whether it's on a built-in speaker, wired or Bluetooth headphones. However, some profiles can be specifically optimized for headphones.

Dolby Atmos, if supported by your model, is a feature that creates virtual surround sound, which is especially noticeable when watching movies through the built-in speaker, and switching between Auto, Video and Music modes can dramatically change how you experience an audio track.

Also in this section, you often find the setting "High volume in headphones." If you switch to quiet headphones, activating this option will help compensate for the lack of decibels, although it can introduce slight distortions at maximum values.

Problems Resolving: The sound does not switch

When you plug in your headphones and the sound keeps coming out of the speaker, it's a common software error. Often the culprit is the Bluetooth cache or driver conflict after the MIUI update. The first step should always be to reboot the device, which resets the temporary audio service files.

If the reboot didn't work, try turning off "Absolute Volume" in the developer menu. To access this menu, you need to click on the build number in the About Phone section several times. Then, in the advanced settings, find the Developer section and turn off the Absolute Volume switch.

The table below will help diagnose the cause of the problem:

In rare cases, the problem lies in the physical contamination of the 3.5 mm connector or charging port. Pile from the pocket, stuffed inside, can prevent the plug from fully contacting, which makes the phone does not recognize the connection and does not switch the sound.
