The first time you use Blackboard Collaborate it will use the audio output device that is the system default at the time your session is launched. If you are on a Windows or Linux system, you can select a different device through the Audio Setup Wizard or the Speaker Settings Preferences dialog.

To change the output device, do so in one of two ways: Windows and Linux through Speaker Settings (Tools > Audio > Speaker Settings…); or using the Audio Setup Wizard. Mac Blackboard Collaborate Web Conferencing uses the system’s current speaker device. To select a different device, change the system default under System Preferences, Sound panel, Output tab.

To change your output device, do the following: From the Tools menu , select Audio > Speaker Settings… Speaker Settings dialog box appears. From the list, select the audio output line you would like to use. Click on Apply Click on OK to save your change and close the dialog box.
