Troubleshooting 

• Make sure the computer has a mic/webcam. Most current laptops have a webcam and mic, but desktops usually don't.
• Check the computer settings to make sure the camera and sound settings are correct. For the mic, check if the input sensitivity is too low or too high which could cause issues. 
• Restart the computer.
• For PCs/Windows, check the drivers to see if they are installed and updated. 
• For Macs, make sure your operating system is updated. 

• Check the computer settings to make sure the camera and sound settings are using the correct source. If there are multiple devices plugged in, there's a chance the webcam also has a built in mic and the settings are set to the default input and not to the one you require. Check the input sensitivity of your mic to ensure it is not too low or too high which could cause issues. 
• Check the settings in the application to make sure the correct peripherals are selected. Also check to see if anything is muted in either the application or computer settings. 
• Check the sound level as it can reset for peripherals back down to 0 when plugged in.
• If you are using a headset/mic, there may be physical buttons on the device that also mute sound output, mic input and overall sound control. This will vary by device. 
• Unplug the peripheral/s and plug them back in.
• Try another port on the computer if available.
• Restart your application.
