Before delving into technical details, make sure that the sound in the application is not muted programmatically. Often, users accidentally click on the microphone or speaker icon during a meeting, resulting in silence. Here's what you need to do first:

• 🔊 Check the microphone icon in the lower left corner of the meeting screen. If it is crossed out in red, click on it to turn on the microphone.
• 🔈 Make sure the sound is not muted on the device. Use the physical volume buttons on your smartphone or check the slider in the notification panel.
• 📱 Activate the "Speakerphone" modeif the sound is too quiet. To do this, tap the speaker icon in the upper right corner of the meeting screen.

If after these manipulations the sound does not appear, proceed to the next step - checking application permissions. On devices with Android 12 and newer microphone permissions and speakers may be reset after system updates, so they need to be confirmed again.

Setting microphone and speaker permissions

Android strictly controls app access to hardware components, including the microphone and speakers. If Zoom did not request permissions when first launched or they were revoked, the sound will not work. To check and fix this:
