Error Messages

Avoid Call Echo

• We recommend using a USB headset. See Mic & Speakers Device Recommendations.
• Reduce the volume of built-in or external speakers.
• Webcams with microphones can pick up additional noise and cause echo. Using a Webcam for your audio is not recommended.
• Laptops with built-in microphones can pick up noise and cause echo. Using a built-in microphone for your audio is not recommended. If you know how to turn off your laptop's built-in microphone, turn it off for your presentation (check your laptop's owner manual).
• If you suspect echo from an attendee, check who is talking at the bottom of the Audio pane and mute that attendee or ask the attendee to lower his/her speaker volume.
• Reduce background noise (see next section).

Avoid Background Noise

• Present from a quiet location.
• If using a microphone, move the microphone closer to your voice and away from competing sounds (e.g., computer fans).
• Avoid moving or touching the microphone during your training session.
• Use a good quality headset. Webcams and built-in microphones can pick up noise and are not recommended.

Dropped Words, Delay, Robotic Sound

Dropped words, delay or robotic sound is often due to poor network performance, lack of memory or high CPU usage.

• Close all applications you are not using for your presentation.
• A dial-up internet connection can cause poor performance. For optimum performance when using Mic & Speakers, we recommend a broadband internet connection. See System Requirements.

No One Can Hear You

Check Sound Device Settings:

• Make sure you selected the correct sound devices in the Audio Pane of your Control Panel. See Audio: Using Mic & Speakers.
• If you are using a microphone, check to see if your microphone has a physical mute/un-mute button on it and that your microphone is not muted.
• Check to see that you're not muted by clicking the Audio icon in your Control Panel or Grab Tab.
• If an attendee can't hear you, his/her speaker volume may be off or set too low.
• Analog microphones are sometimes too quiet; we recommend using a USB headset or USB desktop microphone instead.
• If you are using a desktop microphone, avoid touching the microphone since it may cause a reduction in the volume of your voice.
• If you are speaking loudly, try speaking at a lower level.

Internet Connection

• The speed of your Internet connection can affect 1- way sound. For optimum performance when using Mic & Speakers, we recommend a broadband Internet connection. See System Requirements.
