How to listen to WhatsApp messages through the speaker on Xiaomi

Modern smartphones Xiaomi, Redmi and POCO are equipped with powerful multimedia capabilities, but the standard behavior of the system when playing voice messages in WhatsApp is often bewildering for users. By default, the application translates the sound into “talk mode”, directing the audio stream to the upper auditory speaker, which forces the phone to the ear, as in a normal call.

This behavior is dictated by the logic of developers who want to ensure privacy in crowded places, but in the home or when listening to long audio messages, this format is extremely inconvenient. Users have to find a way to switch the output of sound to the main multimedia speaker, usually located at the bottom of the case or combined with a conversational one in a stereo pair.

In this article, we will discuss all the current methods of switching sound, features of the MIUI shell and HyperOS, as well as consider typical software failures that can interfere with the normal operation of the audio output, you will learn how to configure automatic playback and what hidden settings can affect this process.

The principle of the audio stream in messengers on Android

Understanding how the Android operating system distributes sound streams is key to solving the problem: The system distinguishes between several types of audio channels, and each is directed to different hardware components of the smartphone. WhatsApp initially reserved channel for voice messages STREAM_VOICE_CALL, which forces the upper speaker to activate.

However, modern versions of Xiaomi messengers and shells have learned to recognize the context of use. If you are in hands-free mode or connected a headset, the system automatically redirects the flow. The problem occurs when a proximity sensor or software bug mistakenly classifies the situation as an "ear phone", blocking access to the main speaker.

Importantly, on Xiaomi smartphones with stereo speakers (where the top speaker is paired with the bottom), switching can be incorrect due to aggressive battery optimization or errors in audio drivers, which is why manually controlling the priority of output devices becomes a necessary skill.

⚠️ Warning: Do not confuse the "Loud Communication" mode during a video call with the playback of normal voice messages. These are different audio streams, and the settings for them can be applied independently.

Basic ways to switch to loud communication

The easiest and most obvious way to get WhatsApp to play audio through the main speaker is to manually activate the hands-free mode during the listening session, and when you click on a voice message, the playback control panel appears on the screen, and it has a speaker icon that is responsible for routing the sound.

If you click on this icon, it changes its status and the sound has to move from the top speaker to the bottom (main).In some versions of the MIUI shell, this switch can be hidden or have a different visual style, for example, look like the icon of a phone with waves. Once this mode is activated, all subsequent messages in the current dialogue will also be played loudly.

There is also an alternative method related to the physical position of the device: a proximity sensor located next to the front camera or in the screen blocks the transition to speaker communication if it believes that the phone is near the ear. Make sure you keep the smartphone at least 10-15 cm away from your face when you launch the message so that the sensor does not intercept control.

• 🔊 Click on the speaker icon in the WhatsApp player interface immediately after playback starts.
• 📱 Remove the smartphone from the face and body so that the proximity sensor does not activate privacy mode.
• 🔄 Turn the screen into landscape mode (if supported by the app), which sometimes forcibly changes the audio stream on the media.
• ⚙️ Check if the notification curtain is “Vibration Only” or “No Sound” mode, which may conflict with the speakerphone.

Sound and notification settings in MIUI and HyperOS

Xiaomi shells have a deep level of customization, which extends to sound management. In the system settings section, there is a menu that allows you to configure the behavior of audio notifications and multimedia in detail. To access these parameters, you need to go to Settings → Sound and vibration.

You should look at the "Notification Sound" and the associated extensions here, and some versions of HyperOS have "Look up in your pocket" or similar algorithms that can misidentify where your phone is in your pocket and jam the sound or turn it into quiet mode, and turning off these options can solve the problem.

💡

If after the system update the sound is gone, try resetting the sound settings to the factory in the menu "Sound and vibration" -> three points in the corner -> Reset settings.

Also important is the sound profiles, so make sure that the "Normal" profile is activated, not "No sound" or "Do Not Disturb" profile, and in "Do Not Disturb" mode, the system can block audio output through an external speaker for incoming messages, even if you try to turn them on manually.

Use of Bluetooth devices and headsets

Often users want to listen to messages through a connected Bluetooth headset or speaker, but the sound still goes through the phone's speaker, or vice versa.In Android, audio output is given priority to the last connected device, but WhatsApp can ignore this rule if it does not give the appropriate permissions.

When connecting wireless headphones, make sure that both Media Audio and Incoming Calls are activated in the Bluetooth settings for the device. If the call profile is disabled, the messenger can perceive the headset as inaccessible to voice messages and leave sound on the phone.

There is a nuance with Xiaomi devices that support high-resolution codecs (LDAC, aptX HD), sometimes when you switch to speaker, there is a codec conflict in the application itself, and the sound simply disappears, in which case the temporary switching of the codec from the Developer menu to the basic SBC helps.

• 🎧 Check that the Bluetooth device settings include the profile "Incoming calls".
• 🔌 When connecting a wired headset with a microphone, the system will automatically switch the flow to it; to return to the speaker, you need to turn off the headset.
• 📶 Make sure the distance to the Bluetooth device is not greater than 5-7 meters for stable voice transmission.
• 🔄 Rebooting the Bluetooth module via the “For Developers” menu can eliminate lags when switching.

Solving proximity sensor problems

One of the most common reasons that the sound doesn't go to the speaker is because the proximity sensor malfunctions or gets contaminated, and it's at the top of the screen, and it's responsible for quenching the screen and switching the sound to ear mode, and if there's a poor quality protective film on the screen or a little dirt in the sensor area, the phone will think it's pressed against the head.

To diagnose this problem, Xiaomi smartphones have an engineering menu. You can check the sensor by dialing the code ##6484##. In the CIT menu, you can find the "Proximity sensor" item and cover the top of the screen with your hand. If the indicator does not respond or burns constantly, the problem is hardware or calibration.

⚠️ Attention: If the proximity sensor calibration is knocked down, the screen may go out while watching video or reading, and the sound will go to the top speaker, in which case only resetting the calibration through the engineering menu or flashing the flashing will help.

Also, some cases with thick sidebars can overlap the sensor area, remove the protective case and check if the sound behavior on WhatsApp changes, and if the problem disappears, then it was a mechanical obstacle.

Specifics of WhatsApp on different versions of Android

The behavior of the messenger can vary dramatically depending on the version of the operating system. On older versions of Android (9, 10), audio stream management was less flexible, and applications more often relied on the default system settings. Android 12, 13, 14 and later introduced stricter privacy rules that can limit the access of applications to switch speakers without explicit user action.

Xiaomi’s HyperOS devices (based on Android 14) have new power consumption algorithms that can “freeze” background sound processes. If you rolled WhatsApp and the sound disappeared or became quiet, it may have limited the background activity of the app.

Also, beta versions often feature experimental audio management features that may not work well, and if the problem has occurred after the app update, it makes sense to roll back to the previous version or wait for a patch.

Additional tools and third-party solutions

If the regular tools don’t help, you can turn to third-party sound management tools. In the Google Play store, there are equalizer applications and amplifiers (for example, Volume Booster GOODEV or Precise Volume), which allow you to create separate volume profiles for different applications.

These utilities can be used to force the maximum volume to the media channel, ignoring system constraints, but be careful: excessive amplification can lead to the rash of speakers or damage, especially in the budget models of Redmi and POCO.

Another solution is to use automation through applications like MacroDroid or Tasker, and you can create a macro that says, "When you start WhatsApp, turn on the media volume at 100% and activate the speakerphone," which requires customization, but will provide a fully automatic transition to the desired mode.

⚠️ Note: Using third-party amplifiers can cause audio distortion and loss of speech intelligibility. Use them only if the standard volume is not enough.

💡

The most effective method is to manually switch through the WhatsApp player interface, as it works at the application level and is not dependent on system conflicts.
