If your sound card doesn't allow you to record sound, you may try to use Replay Video Capture or WM Capture to record video with audio. The Universal Audio Driver allows you to record audio on virtually ANY system. You should select this if the Audio Test fails to locate any available recording input.

Troubleshooting: I'm having trouble recording audio.
On some PC's, only the Universal Audio Driver will work. Go to Settings, Audio Setup/Test, and select the Universal Audio Driver. Use the Universal Audio Driver only if the Test option fails to locate a working audio recording line.

Troubleshooting: The Universal Audio Driver Option isn't working for me
To use the Universal Audio Driver, in some cases you may need to open Replay Video Capture or WM Capture before opening your browser or video playback application.
