Troubleshoot: Events

This section answers questions that are frequently asked while attending Cornerstone Classroom events.

Why can I not join an event?

You may not be registered for the event. Check if the event is configured to allow only registered participants or requires a pre-enrollment.

For more details about events, see Attend an event.

Why am I not able to activate my microphone or camera?

Ensure that you are not using an incorrect device or if your connected device is not having a functional issue. Use the Audio setup wizard to check if you can hear your own audio and the Video setup wizard to check if you can see your own camera.

If you clear the first set of audio and video checks and still cannot activate your mic or camera, then check if your event leader or co-presenter has disabled your microphone or camera. If so, then ask your event leader to enable them for you so that you can use them during the event.

For more details about controlling participant actions, see Manage participants.

Why is my voice not audible to attendees of an event?

By default, your microphone is muted. To speak during a session, enable your microphone by clicking the Muted button. Remember to click the button again to mute the microphone. Alternatively, you can activate the microphone by pressing down and holding the CTRL key on the keyboard.

Also ensure that you are not using an incorrect device or if your connected device is not having a functional issue. Use the Audio setup wizard to check if you can hear your own audio.

For more details about audio, see Manage audio.

Why do I hear an echo during a meeting?

You would hear an echo in a meeting if a device is transmitting audio back to your microphone, which creates an audio loop. The audio echo during a meeting can be due to the following possible reasons:

  • Multiple devices with an active audio are in the same physical room.
  • Both the computer and telephone audio are active for a participant.

To prevent the echo, the participants causing the echo can either mute themselves or use headphones.

You can also use the audio wizard’s record feature to hear your own audio to check how it is heard by others.

To prevent an echo during a meeting, the meeting leader can:
  • Mute the participant who is the source of the audio echo.
  • Mute all participants in the meeting.

For more details about audio, see Manage audio.

Why am I not able to record an event?

Check if you have started the session. Recording is allowed only when the session is in progress. It is not allowed in the pre-session mode.

If you are still not able to start the recording, then the recording capability may be disabled for all events in your domain. Contact your Cornerstone Classroom domain administrator to enable this facility.

For more details about recordings, see Record events.

Why am I not able to perform AppShare?

If you are an event leader or co-presenter, check if you have started the session. Sharing an application (AppShare) is allowed only when the session is in progress. It is not allowed in the pre-session mode.

If you are a participant, then you may not have permissions to perform AppShare. Only event leaders or co-presenters can grant you the permission to perform AppShare.

For more details about AppShare, see Share an application.

When a leader launches the App on a Mac OS Big Sur or Mac OS Monterey, and tries to perform AppShare, other participants can see only the leader's desktop.

This issue is caused mostly due to security permissions of the operating system.

For AppShare to function correctly, you must enable Screen Recording on your machine as follows:
  1. Click the Apple menu.
  2. Click System Preferences > Security & Privacy > Privacy > Screen Recording.
  3. Click the lock icon to make your changes (you will need to enter your admin password).
  4. Click the check box next to the Cornerstone Classroom app client. A notification window appears prompting you to restart the app.
  5. Restart the app client.
  6. Try AppShare again.

Why am I not audible to others even after I unmute the microphone?

If you try to speak by unmuting the microphone and if no active audio channels are available in a Cornerstone Classroom session, then your voice cannot be heard by other participants of the session.

In such cases, the Cornerstone Classroom client displays the following message indicating the unavailability of audio channels:

All the available audio channels are in use. Please use the Raise Hand or the text chat option to request other speakers to deselect their mic, if not in use.

This message is not displayed to other participants in the session, though.

Only when one or more of the remaining participants mute their microphone, and if the maximum number of audio channels for the session has not been reached, then you are audible to others.
Note: This message is displayed only if you are using the Cornerstone Classroom App client. It is not displayed in the Express client.

For more details about audio, see Manage audio.

Why do I see a low-quality video stream in the meeting?

There may be multiple reasons for seeing a low-quality video stream during a meeting. Some of the more common causes are:
  • You may be facing a low Internet bandwidth issue. Try to reset your network adaptor or contact your Internet provider if the issue persists.
  • Your webcam may be using a Standard Definition (SD) resolution. Check your webcam settings or upgrade to a High Definition (HD) Web cam.
  • Your Cornerstone Classroom App may be configured to use only the Standard Video mode. Upgrade to the Cornerstone Classroom Premium Video mode. However, note that this may require an additional fee. For more details about videos, see Use videos.

Why do I not see any markup tools?

If you are not a leader or co-presenter in an event, then, by default, you do not have access to the markup toolbar in the Whiteboard. Markup toolbar privileges are associated with the microphone. The session leader must grant you the microphone privileges to give you access to the markup toolbar.
