Video conferencing in Zoom has long become a part of everyday life - be it work calls, online lessons or family chats. But what to do if the sound suddenly disappears on your Androidsmartphone? Do you see your interlocutors, but they don’t hear you (or vice versa)? The problem may lie both in the settings of the application itself and in the operating system settings. In this article we will analyze all possible reasons for the lack of sound in Zoom on Android —from a banal muted microphone to conflicts with other applications.

It is important to understand that the solution algorithm depends from specific situation: either you can’t hear other participants, or they can’t hear you, or the sound disappears periodically. We have structured the material so that you can quickly find a solution for your case - without unnecessary technical details. And if you are a user Samsung, Xiaomi or Huawei, pay attention to specific nuances these brands.

1. Basic checks: microphone and speakers

Before digging deep into the settings, make sure that the problem is not on the surface. In 60% of cases the sound in Zoom disappears due to basic things:

  • 🔇 The microphone is muted in Zoom itself - icon with a crossed out microphone at the bottom screen.
  • 🔊 The sound on the phone is muted —check the physical switch (if any) or the volume slider.
  • 📵 Do not disturb mode or "Mute" is active in the settings Android.
  • 🔌 Headphones are connected, but the sound comes through them, and not through the phone's speakers.

Start with the obvious: during a call to Zoom touch the screen so that the control panel appears. If the microphone icon is crossed out in red, click on it once. Do the same with the speaker icon (loudspeaker with waves). On some models Samsung Galaxy (A and S series) after updating to Android 14, the sound in Zoom can automatically switch to Bluetooth devices, even if they are turned off - check this in the connection settings.

If there is still no sound, proceed to the next step - checking application permissions.

2. Checking permissions for Zoom in Android

Android strictly controls access to the microphone and speakers If Zoom you did not request permissions when you first started (or you accidentally disabled them), the sound will not work. how to fix this:

  1. Open Settings → Applications.
  2. Find Zoom in the list and tap on it.
  3. Go to Permissions (or Rights on some firmware).
  4. Make sure the switches are opposite Microphone and Sound (or Audio recording) are active.

On Xiaomi (MIUI) and Oppo (ColorOS) may require additional permission to Autorun - without it Zoom will not be able to correctly manage audio streams. To enable it:

Settings → Applications → Zoom → Battery → Autorun (enable)

If permissions are already enabled, but there is no sound, try resetting them:

  • In settings Zoom click Storage → Clear cache.
  • Then return to Permissions and disable/enable them again.
💡

On some phones (for example, Realme i OnePlus) after updating to Android 13+, Zoom may lose access to the microphone. Solution: delete the application, restart your phone and install Zoom again from Google Play.

3. Sound settings inside the Zoom application

Itself Zoom has its own audio settings that may conflict with system settings. To check them:

  1. Open Zoom and log into your account.
  2. Tap on the icon ⚙️ Settings (usually in the upper right corner).
  3. Select Sound (Audio in the English version).

Here pay attention to the following parameters:

Parameter Recommended value What to do if it doesn’t work
Always use Internet audio Enabled (checkmark) Disconnect and reconnect to the conference
Automatically connect audio Enabled Manually click "Join with audio" when entering conference
Noise reduction Medium or High Disable completely if the sound is interrupted
Use original sound Disabled (if not a musician) Enable if you are streaming music or high-quality audio

If you are connecting to the conference through a browser (not through an application), check that there is no icon in the address bar next to the URL 🔇 (microphone blocked). Click on it and allow access.

4. Conflicts with other applications

Android allows only one application to actively use the microphone at a time. If you are running:

  • 🎵 Music player (Spotify, YouTube Music)
  • 🎮 Game with voice chat (PUBG Mobile, Free Fire)
  • 📱 Another calling application (WhatsApp, Discord)

— Zoom may not be able to access the microphone. Close all background applications via Recent (square button at the bottom of the screen) and try again.

Especially often conflicts arise with:

  • Google Assistant —if it is activated by voice (Okay, Google), it can block microphone.
  • Screen recording applications (for example, AZ Screen Recorder).
  • VPN clients —some (for example, ProtonVPN) change the routing of audio streams.

To check if another application is interfering:

  1. Open Settings → Applications.
  2. Tap on the three dots in the upper corner and select Special access → Usage microphone.
  3. See which applications have recently used the microphone.
What to do if the sound is working, but the interlocutors hear an echo?

Echo in Zoom on Android usually occurs due to:

1. Double audio capture — when the microphone picks up sound from the speakers (for example, if you are using a phone without headphones in a room with reverberation).

2. Conflicts with Bluetooth devices —even if the headphones are disconnected, the system may try to route sound through them.

3. Hardware problems —on cheap phones (for example, Redmi 9A or Samsung Galaxy A03) the microphone and speaker are too close.

Solution:

- Connect wired headphones with a microphone.

- In the Zoom settings, disable Echo cancellation (Settings → Sound → Advanced).

- Reduce the volume of the phone speakers to 50%.

5. with Bluetooth and connected devices

If you have ever connected to a phone Bluetooth headphones, speakers or smart watch, Zoom can automatically redirect audio to them - even if the devices have been disconnected for a long time. This is especially true for phones Samsung i Google Pixelwhere audio routing works. aggressively.

How to reset audio routing:

  1. Open Settings → Connected devices (or Bluetooth).
  2. Make sure all Bluetooth devices are turned off.
  3. Go back to Zoom and manually select Phone speaker in the sound settings.

If the sound still goes in the wrong direction, reset the audio settings:

Settings → System → Reset → Reset Wi-Fi, mobile network and Bluetooth settings

Attention: this will delete all saved networks and paired devices!

💡

On phones OnePlus and Oppo with OxygenOS/ColorOS 13+ there is a bug: after connecting to a Bluetooth device, the sound in Zoom may disappear until the phone is rebooted. The solution is to disable the "High Quality Audio" option in the Bluetooth settings.

6. Updates, cache and reinstallation of Zoom

If all the previous steps did not help, the problem may be in the app itself. An outdated version Zoom, a damaged cache or a conflict with the phone's firmware are common culprits for the lack of sound.

Proceed in order:

  1. Update Zoom:
    • Open Google Play → find Zoom → click Update.
    • If there is no button, your version is current.
  2. Clear the cache and data: 
    Settings → Applications → Zoom → Storage → Clear cache / Clear data

    ⚠️ Attention: clearing data will delete all saved conferences and account settings!

  3. Reinstall Zoom:
    • Delete the application.
    • Reboot your phone.
    • Install Zoom again from Google Play (not from the APK!).

If after reinstallation the sound still does not work, check whether it is blocked antivirus or optimizer (for example, Avast, Clean Master or built-in Battery Saver on Xiaomi). Add Zoom to exceptions.

7. Specific problems on Samsung, Xiaomi and other brands

Smartphone manufacturers often modify Android, adding their own "chips" that can break the sound in Zoom. This is what is typical for popular brands:

Brand Problem Solution
Samsung (One UI) Sound automatically switches to Media instead of Calls In the sound settings, select Calls as priority mode
Xiaomi/Redmi/Poco (MIUI) Microphone is blocked MIUI Security Open Settings → Special. permissions → Microphone usage and allow for Zoom
Huawei/Honor (EMUI) Zoom cannot use the microphone in the background In the battery settings, disable Power consumption optimization for Zoom
Google Pixel Sound problems after updates to Android 14+ Disable Cpatial Audio in the sound settings

On phones Samsung Galaxy S22/S23 and newer may work "Adaptive Sound" function, which automatically adjusts the volume depending on the surrounding noise. This sometimes causes the sound to become too quiet or disappear. To disable: Zoom becomes too quiet or disappears. To disable:

Settings → Sound and vibration → Sound quality and effects → Adaptive Sound (disable)
💡

On Xiaomi with MIUI 14+ after the update, Zoom may require additional permission to “Record screen and sound”. Without it, the microphone will not work, although everything is turned on in the settings.

8. Hardware problems and when to contact service

If you have tried all of the above, but the sound in Zoom still does not work, the problem may be hardware. Signs of a malfunction:

  • 🔊 The microphone does not work in all applications (not only in Zoom).
  • 🎧 The sound disappears even when listening to music or video.
  • 💥 The phone fell or came into contact with water.
  • 🔌 The headphone jack (if any) is damaged.

What you can do yourself:

  1. Try to connect wired headphones — if there is sound through them, the problem is in the phone dynamics.
  2. Use external microphone (for example, from headphones) - if the interlocutors begin to hear you, the built-in microphone is faulty.
  3. Check whether the microphone hole is clogged with dust (carefully clean it with a toothpick).

⚠️ Attention: if the phone is under warranty, do not disassemble it yourself! Contact the service center. The cost of repairing a microphone or speaker on most models (Samsung A54, Xiaomi Redmi Note 12 etc.) is 1,500–3,000 rubles, while independent replacement can damage the cable.

If the sound disappears only in Zoom, but in other applications (WhatsApp, Viber) everything works, try:

  • Create new Zoom account (possibly a problem in the profile).
  • Use web version Zoom in the browser Chrome (open meet.zoom.us).
  • Try alternative applications (Google Meet, Microsoft Teams) - if there is sound there, the problem is definitely in Zoom.
How to test the microphone for functionality without Zoom?

1. Open the application Dictaphone (standard or third-party, for example, Easy Voice Recorder).

2. Start recording and say something.

3. Stop the recording and listen to it.

4. If the recording quiet or missing - the microphone is faulty.

To check the speaker:

- Turn on any video on YouTube - if there is no sound, the problem is in the speaker or system settings.
