I am trying to record a 15 second segment from a CD using Sound Recorder. In Record Control I have my SB designated as my mixer device, CD Audio selected and volume turned up at 75%. I play the CD using Windows Media Player, and click on the "record" button in Sound Recorder. The slider is moving from left to right. After 10 - 15 seconds I click the "stop" button. Then I click on play, and nothing was recorded. However, I was able to record and play back my voice using a microphone. Suggestion will be greatly appreciated!
