The application Zoom has become an integral part of everyday life - from work meetings to online lessons. But what to do if your microphone is persistently silent during a conference? The problem may lie both in the settings of the application itself and in the system parameters of the phone. This article will help you understand all the nuances: from basic steps to hidden settings that are often overlooked. Android smartphone persistently silent during the conference? The problem may lie both in the settings of the application itself and in the system parameters of the phone. This article will help you understand all the nuances: from basic steps to hidden settings that are often overlooked.

We will look at not only standard ways to turn on the microphone, but also rare causes of problems - for example, why the sound may disappear after an update Android 14 or as a conflict with other applications (like Google Meet) affects the operation of audio. And if you use external microphone or Bluetooth headset, you will find separate instructions for these cases.

Important: the algorithm of actions may vary slightly depending on the version Zoom (5.15.0 and later) and shells Android (MIUI, One UI, ColorOS etc.). But the general principles remain universal.

1. Basic ways to turn on the microphone in Zoom

Start with the obvious - check if the microphone is muted directly in the interface Zoom. During a call, there is a "Microphone" button (microphone icon) in the bottom toolbar. If it is crossed out in red, click on it once.

If the button is active, but there is still no sound, try:

  • 🔄 Switch microphone: double-click on the microphone icon - this will forcefully restart the audio stream.
  • 📱 Change audio source: tap the arrow next to the microphone button and select Use telephone audio (if a headset is connected).
  • 🔇 Check volume: sometimes the problem is not in the microphone, but in the speakers - increase the volume using the physical buttons on the phone.

If these steps do not help, go to system settings.

2. Setting microphone permissions on Android

Android 10 and later requires explicit permission to access the microphone for each application. If you do not give it, Zoom physically will not be able to use audio. You can check this like this:

  1. Open Settings → Applications.
  2. Find Zoom in the list and tap on it.
  3. Go to Permissions → Microphone.
  4. Make sure that is selected Allow or Allow only while using the application.

On some firmware (for example, Xiaomi MIUI) may need to be additionally included Autoplay and Show pop-ups for Zoom, otherwise the application will not be able to correctly manage audio in the background.

☑️ Check Zoom permissions

Done: 0 / 4
⚠️ Attention: On Samsung Galaxy s One UI 5.0+ there is a separate setting Permissions for unused applications. If Zoom has not been opened for a long time, the system may automatically disable access to the microphone. Check this in Settings → Device care → Automation.

3. Problems with the microphone on specific Android models

Some smartphones have unique “features” that interfere with operation Zoom. Here are the most common cases:

Model/Brand Problem Solution
Xiaomi Redmi Note 10/11 The microphone only works through the speaker, not through headphones Disable Voice enhancement in settings MIUI (Settings → Sound → Sound effects)
Samsung Galaxy S22/S23 Zoom does not see Bluetooth headset Reset Bluetooth settings: Settings → Connections → Bluetooth → ⚙️ → Reset settings
Realme GT/ Narzo Noise canceling mutes the microphone V Zoom select Settings → Audio → Disable noise reduction
Google Pixel 6/7 Microphone delays Disable Adaptive sound in Android settings

On Huawei i Honor s EMUI 12+ may need to be added manually Zoom to the list of "Protected applications" (Settings → Applications → Protected applications), otherwise the system will block access to the microphone after 30 minutes of use.

4. Checking microphone hardware problems

If the microphone does not work not only in Zoom, but also in other applications (WhatsApp, Dictaphone), the problem may be hardware. Carry out a quick diagnosis:

  • 🎤 Test with a standard voice recorder: record your voice and check the sound quality. If the recording is quiet or with interference, the microphone is damaged.
  • 🔌 Checking the connector: if you are using a wired headset, try a different cable - often the problem is in oxidized contacts.
  • 📱 Cleaning the microphone hole: on some models (Samsung A52, Oppo Reno) the microphone becomes clogged with dust. Gently clean the hole with a soft brush.

On Android you can use microphone testing applications, for example Microphone Test or Sound Meter. They will show the signal level in decibels - if during loud speech the value is lower 40 dB, the microphone is faulty.

How to clean the microphone without damage?

Use a dry soft brush (for example, drawing) or a can of compressed air. Do not use wet wipes or alcohol as this may damage the microphone diaphragm. For complex contamination, contact the service center.

5. Conflicts with other applications

Zoom may conflict with apps that monopolize access to the microphone. Typical "culprits":

  • 🎵 Music applications (Spotify, YouTube Music) in the background.
  • 🎮 Game launchers (Xbox Game Pass, Steam Link).
  • 📱 Voice assistants (Google Assistant, Alice).
  • 🔒 Antiviruses (Kaspersky, Avast) with protection function microphone.

Solution:

  1. Close all background applications through Recent → Close all.
  2. In settings Android check Special access → Using the microphone and disable unnecessary apps.
  3. For Google Assistant: say "Okay, Google, quit" or turn it off in Settings → Google → Devices and accounts → Assistant settings.
💡

If you often use Zoom and music apps at the same time, add Zoom to the list of "Battery optimization exceptions" (Settings → Battery → Battery optimization). This will prevent the microphone from automatically turning off.

6. Updating Zoom and Android to fix errors

If the microphone stops working after updating Zoom or Androidthe problem may be a software bug. Here's what to do:

For Zoom:

  • Update the application to the latest version via Google Play.
  • If the update does not help, clear the cache: Settings → Applications → Zoom → Memory → Clear cache.
  • As a last resort, reinstall Zoom.

For Android:

  • Check for system updates: Settings → Software update.
  • On Samsung after major updates (One UI 5.0 → 6.0), you may need to reset your network settings: Settings → General management → Reset → Reset network settings.
⚠️ Attention: On some devices (Xiaomi, Redmi) after updating MIUI application permissions are reset. Always check access to the microphone after the update!
💡

Update Zoom and Android regularly - in 80% of cases, problems with the microphone are solved by installing the latest security patches.

7. Alternative methods for connecting a microphone

If the built-in microphone does not work, consider alternatives:

Bluetooth headset:

  • Connect the headset to startup Zoom.
  • In the settings Zoom select it as a sound source: Settings → Audio → Use as a microphone → [Headset name].

External USB/Type-C microphone:

  • Connect the microphone via an adapter (if necessary).
  • In Zoom select Settings → Audio → Microphone → External device.
  • On Samsung DeX or Android with OTG an additional driver may be required (install USB Audio Player PRO).

If you have a computer, you can transmit sound through it:

  1. Connect your phone and PC to the same Wi-Fi network.
  2. Install on your PC Voicemeeter or OBS Studio with the plugin Virtual Audio Cable.
  3. In Zoom on your phone select Settings → Audio → Microphone → Connect via IP (Premium account required).
