Users of audio devices that feature Realtek's HD Audio Drivers might encounter an Unable to Configure Audio message when logging in to an Elluminate Live! session.

The audio trouble you have encountered is due to the audio drivers used by your sound card. The Realtek HD controls four audio devices:

1. Realtek HD Audio rear output
2. Realtek HD Front Green Jack
3. Realtek HD Front Pink Jack
4. Realtek HD Audio rear input

It is likely that you have your speakers plugged in to the first device, and your microphone plugged in to the third device. You can plug a microphone into any of the last three devices. However, the second and third devices are missing components that are required configure the microphone. That component is present only in the fourth device.

To allow the audio to work with Elluminate Live!, make the following two changes to your system:

1. Plug the microphone in to the rear input microphone jack, which is on the back of the computer near to where the speakers are plugged in.
2. Change the Recording Preferred Device:
   1. Open your Control Panel
   2. Open the Sound and Audio Devices control
   3. Select the Audio tab
   4. Change the Sound Recording Preferred Device to Realtek HD Audio rear input.

Try again to access Elluminate Live! and you should find that the audio functions normally. If this is unsuccessful, please contact Elluminate Support.
