You joined an important online meeting at Zoom on your Xiaomi smartphone, but suddenly you found that the sound didn't work: the people you spoke to couldn't hear you, and you couldn't hear them either.

The problem is familiar to many users of Redmi Note 12, POCO X5 or Mi 11, especially after app or MIUI updates. 80% of the time, the fault in the settings of the Zoom itself, not the hardware breakdown of the phone.

In this article, we will discuss all possible reasons for the lack of sound in Zoom on Xiaomi Android devices – from basic checks to hidden system parameters. You will learn how to turn on the microphone and speakers right during the conference, why the sound may disappear after locking the screen, and what to do if some Xiaomi models (for example, Redmi). 10C) Zoom only works through headphones, even if they're not connected.

1.Basic check: Is the sound on in the Zoom itself

Before you go through the phone settings, make sure the problem isn't with the app itself. During a Zoom conference, the sound can be turned off for several reasons:

• 🔇 Microphone off – the icon with the crossed microphone is active (red).
• 🔊 Speakers are off – the volume icon is crossed out or gray.
• 📵 Do Not Disturb in Zoom (disables all notification sounds).
• 🎧 Automatic switching to headphones that are not in port.

To turn on the sound:

1. Tap the screen during the conference to allow the control panel to appear.
2. Click on the microphone icon (if it is red, the sound is turned off).
3. Slip the volume icon and select Speaker (not Bluetooth or Headphones).
4. If the sound still does not appear, press three dots (⋯) → Sound settings → Check what you have chosen to always use the speaker.

On some Xiaomi models (such as the POCO F4), the sound in Zoom can stick on the headphones even after they are turned off, to reset the settings, restart the application or switch audio mode manually.

2.Permissions Verification for Zoom in MIUI

Xiaomi is known for its strict app permissions policy, especially in the latest versions of MIUI 13/14. Unless Zoom requested access to a microphone or speakers on its first run, the sound won't work.

1. Open Settings → Applications → Application Management.
2. Find Zoom on the list and tap it.
3. Go to Permits. → Microphone and Sound.
4. Make sure both permissions are set in the Allow or Ask position each time.

• 🔒 Check if Zoom has been added to Special Permits → Auto-run (otherwise, the application may not work correctly in the background).

Xiaomi system settings may conflict with Zoom, especially if you use:

• 🎵 Mode "Vibration Only" or "No Sound.
• 🔕 Function "Smart switching of sound" (automatically switches output to headphones).
• 📴 Energy saving that limits applications in the background.

2. Find Zoom and select No Limits.

4. Problems with Bluetooth and "ghost" headphones

One of the most common reasons for the lack of sound in Zoom on Xiaomi is because it sticks on Bluetooth devices that are long disabled, and the system continues to send audio streams to non-existent headphones, and the phone's speakers are silent.

1. Open the Quick Settings panel (swipe down from the top edge of the screen).
2. Hold the Bluetooth icon to open the settings.
3. Turn off Bluetooth or remove all saved devices (click on the gear next to each and select Forget).

• 🎮 Gaming accelerators (Game Turbo) MIUI).
• 🔒 Antiviruses (Avast, 360 Security) that block access to the microphone.
• 📱 Screen recording applications (AZ Screen Recorder).

6.Zoom and MIUI update: why sound disappears after updates

After updating Zoom or MIUI firmware, the sound may stop working because of:

• 🔄 Resetting permits (MIUI 14 automatically revokes microphone access after updates).
• 🐛 Bugs in newer versions of Zoom (for example, 5.15.0 had a sound problem on Android 12)+).
• 📱 Changes in the audio subsystem MIUI (In the 13th version added a new sound driver).

Decisions:

1. Update Zoom to the latest version on Google Play.
2. If the problem has occurred after the MIUI update, check for patches: Settings → About Phone → System Update
3. Reverse to the previous version of Zoom (download APK from the official website).

• 🔊 Contaminated speaker (dust, moisture).
• 🎤 Faulty microphone (often after falls).
• 🔌 Damaged audio connector (if the sound only works via Bluetooth).
• 📱 Failure of the audio codec (for example, on Redmi) 10A post-fix).

How to diagnose:

1. Check the sound in other apps (YouTube, calls) if it's not everywhere, the problem is the phone.
2. Connect headphones: if there is sound in them, and there is no speaker in the speakers - the speaker is faulty.
3. Write down a voice message on WhatsApp: If the microphone doesn’t work, your interlocutors won’t hear you in Zoom.

💡

On Xiaomi models with a 3.5 mm connector (like the Redmi 9A), a common problem is the oxidation of contacts in the audio nest. Clean it with a toothpick soaked in alcohol and restart the phone.

If the hardware malfunction is confirmed:

• 🛠️ Contact Xiaomi Service Center (Warranty covers defects in speakers and microphones).
• 🔧 For self-repair, order original spare parts (for example, the speaker for the Redmi Note 11 is worth it). ~500 rubles.).

💡

On Xiaomi with stereo speakers (POCO X3, Mi 11), the sound in Zoom can be lost due to a malfunction of only one of the speakers. Check both by putting your ear to the top and bottom of the phone.
