Many users with USB microphones find may find that they do not always work in an Elluminate Live! The solution to this is to plug in your USB microphone in before joining an Elluminate Live! session.

When Elluminate Live! starts, it checks the computer's current audio sources to find out which device audio should be sent to and received from. The current audio sources are loaded into Elluminate Live! for use during the current session. Once Elluminate Live! is running, it does not again check the audio sources.

This means that if you plug a USB microphone or headset in while an Elluminate Live! session is in progress, Elluminate Live! will not recognize it. Elluminate Live! continues to run with the settings the computer had when the session started.

To switch to a USB device during a live session, shut down Elluminate Live!, plug in the device, and restart Elluminate Live!. Audio difficulties with USB devices can usually be solved by opening the relevant control panel (depending on operating system) and ensuring that the USB device is set as the default audio device (input and/or output, depending upon device type).
