If you experience audio issues when in a training, please first make sure you are connected to the audio using the audio button in the zoom task bar. If issues persist, log out and log back in to attempt to fix the issue.

Other tips:

Check audio settings

• Make sure that the correct audio output is selected.
• Adjust the sound or volume settings.

Check your device

• Check if the microphone, speakers, or headphones are plugged in and not muted.
• Unplug the device, then plug it back in.
• If it’s a Bluetooth device, ensure that it is turned on and connected properly.
• Make sure that you are using a supported USB device for Zoom.
• Ensure that no other applications are using the microphone at the same time.

Check headphone connectivity

In addition to making sure that your headphones are plugged in and not muted, try the following steps:

• For Bluetooth headphones, troubleshoot common Bluetooth issues.
• For wired headphones on Windows devices, you may need to adjust the volume mixer within your device's settings to ensure that the Zoom app is not muted.

Test your audio

• Test your audio to ensure that it is working properly.
• Record a message to test your microphone, then listen to the playback to test your speakers or headphones.

Check antivirus software

• As some antivirus software, such as Kaspersky, may prevent applications from accessing your mic, check your antivirus software to ensure Zoom is allowed to access your mic.

Check for any audio drivers

• Check for any audio drivers updates.
• Uninstall and reinstall any audio drivers.

Perform general troubleshooting for audio issues

• Make sure that you have downloaded the latest version.
• Uninstall the app, then download and reinstall it.
• Check for any available operating system updates.
• Clear cache and cookies from the settings.
• Restart your browser or device.
