Make sure that your microphone/speakers are plugged in to your computer before you run the Wimba Setup Wizard. Wimba won't recognize your sound card and will send a "fatal audio error" message if this equipment isn't present before the setup process.
For additional assistance with Wimba, you can check the Wimba FAQs, visit the Student Computing Help Center in Barnard or call 704-687-6400. You can also submit this problem to the HelpDesk Online and track the status. When the Help Center is closed, you can get Wimba Support at 866-350-4978 or email technicalsupport@wimba.com.
