If you are facing any of the stated Audio and Video issues in Blackboard Collaborate, follow the instructions provided in this article on how to resolve them.
Audio and Video issues may include:
- No Audio or Video
- Poor Audio or Video
- Garbled Audio
- Distorted or pixilated Video
Troubleshooting instructions to help resolve the issues:
- It is highly recommended to use a headset. Avoid using the computer's built in audio components. This helps prevent background noises from being picked up by the on-board microphone.
Check to see that the correct speakers are selected for your OS.
- On Mac, go to the Apple icon (on the top-left corner) > System Preferences > Sound
- On Windows, go to Control Panel > Hardware and Sound > Sound or search for Sound and select Sound from the Control Panel in the search menu.
Make sure the proper audio device is selected for use by Collaborate Ultra.
- On Blackboard Collaborate, click on My Settings (your avatar) > Audio and Video Settings > Setup Your Camera and Microphone.
- Make sure the microphone is positioned appropriately. For instance, placing the microphone directly under your nose will result in breathing noise, and placing it too far away from your mouth will result in low audio and the disruption due to background noise.
- Make sure that you use a supported web browser. Click here to see a list of supported browsers.

- Close out of your web browser and reopen it or try a different supported web browser.

Check for sustained high CPU usage which is an indicator that your computer is working too hard. High CPU usage for our intents and purposes is defined as sustained CPU usage of 90% - 100%, meaning the CPU Usage doesn't often fall below that level or frequently returns to that level. High CPU usage is most commonly seen when using an older computer or when too many programs are running.
- On Windows, open the Task Manager (ctrl+alt+delete > Task Manager). Total CPU usage is shown at the bottom of the Task Manager screen.
- On Mac, open the Activity Monitor (Go>Utilities>Activity Monitor). Total CPU usage is shown at bottom of the Activity Monitor screen.

- Shut down any unnecessary programs that are running on the computer before starting your Collaborate Ultra session. As a general rule, if you don't plan on sharing an application, close it!
