You joined an important online meeting in Zoombut suddenly discovered that the sound does not work the interlocutors can’t hear you, and you can’t hear them? The problem is familiar to many users of Androidsmartphones. The reasons may be different: from banal microphone settings to conflicts with other applications. In this article we will analyze all possible ways to turn on the sound on Zoom on the phone, and also tell you how to avoid common mistakes.

Malfunction with sound on Zoom often occurs due to software failuresincorrect permissions or hardware limitations. For example, some models Samsung or Xiaomi automatically block the microphone to save battery power. Other devices may “mute” the sound due to the active mode Do not disturb or conflict with the Bluetoothheadset. It is important to understand that the solution depends on the specific situation there is no universal method.

Before moving on to the settings, make sure that the problem is not on the server side Zoom. To do this, check the status of the service on official resources or try joining a test conference. If there is no sound in only one chat, the host may have manually muted your microphone.

1. Checking basic audio settings in Zoom

Start with the most obvious - make sure that the microphone is not muted in the application itself. During a conference, there is a control panel with buttons at the bottom of the screen. If the microphone icon is crossed out in red, it means the sound is muted.

To turn on the microphone:

  1. Tap the screen to open the toolbar.
  2. Tap the button "Microphone" (usually second from the left).
  3. If you are prompted to access the microphone, confirm permission.

If the microphone button is active (not crossed out), but there is still no sound, check volume in the application. Sometimes users accidentally turn the volume down to zero right in Zoom:

  • 🔊 Click on the three dots in the lower right corner of the screen.
  • 📱 Select Sound settings.
  • 🔄 Make sure that The microphone volume slider is not at zero.
💡

If you are using Bluetootha headset, try unplugging it and reconnecting it. Sometimes Zoom "does not see" the device after the first connection.

2. Microphone settings in the Android system

If Zoom everything is configured correctly, but there is still no sound, the problem may lie in system permissions. Android requires explicit confirmation of access to the microphone for each application.

How to check permissions:

  • 📱 Open Settings → Applications.
  • 🔍 Find Zoom in the list and click on it.
  • 🎤 Go to Permissions and make sure that microphone enabled.
  • 🔄 If the permission is disabled, enable it and restart the application.

On some devices (for example, Xiaomi Redmi or POCO) there is an additional function battery auto-optimizationthat can block the microphone from working in the background. To fix this:

  1. Go to Settings → Battery and performance.
  2. Select App energy management.
  3. Find Zoom and set the mode Unlimited.

3. Problems with the headset or speakers

If you use headphones or Bluetoothheadsets, the sound may disappear due to an incorrect connection. Zoom sometimes “forgets” to switch to an external audio device after connections.

What to do:

  • 🎧 Disconnect and reconnect the headset.
  • 🔄 B Zoom click on the arrow next to the microphone button and select the desired device manually.
  • 📱 If you are using wired headphones, check whether the plug is firmly inserted into the jack.
  • 🔊 Try switching to the phone speaker - if sound appears, the problem is in the headset.

On some models Samsung Galaxy (for example, S21 or S22) there is a bug due to which the application does not recognize Bluetoothdevices after the update. In this case, it will help restarting the phone or resetting the settings Bluetooth:

  1. Open Settings → Connections → Bluetooth.
  2. Click on the three dots in the upper right corner and select Reset settings.
  3. Reconnect the headset.
What to do if there is sound, but the interlocutors hear an echo?

1. Use headphones instead of your phone speaker.

2. Reduce the volume of the speakers Zoom (but not the microphone!).

3. Move to a quieter place - sometimes echoes are caused by reverberation in the room.

4. Conflict with other applications

Some apps (for example, screen recordingmessengers or games) may block access to the microphone for Zoom. This is especially true for devices with a small amount of RAM (2–3 GB), where the system forcibly closes background processes.

  • 📱 Close all unnecessary applications via Recent (square button at the bottom of the screen).
  • 🔄 If you were recording the screen, stop it - some apps (for example, AZ Screen Recorder) are monopolizing the microphone.
  • 🎮 Close games or streaming services (such as Twitch or YouTube) that may be using audio in the background.

On devices Huawei and Honor there is a function Privacy protectionthat can restrict access Zoom to the microphone. To disable it:

  1. Go to Settings → Privacy → Permission manager.
  2. Find Zoom and make sure that for microphone installed Allow.
