If you experience heavy audio distortion or very slow playback rate please consider the following configuration sequence:

• Open Windows Control Panel, Find the "Sound" item and open it.
• Click the "Recording" tab on the "Sound" window.
• Select your microphone in the list by clicking on it.
• Click the "Properties" button
• Click the "Advanced" tab on the "Properties" window.
• Uncheck the "Enable Audio Enhancements" checkbox. It must not be selected.
• Click OK (to close the Properties window)
• Click OK (to close the Sound window)

After that enter your live classroom or one of our testing classrooms (here)​ and run the audio test using the button after the volume sliders. Make sure to complete both tests - speakers and microphone after selecting the proper audio devices.
