When Sound Recorder is running on a Windows Vista-based computer, the computer does not go to sleep regardless of how long the system is otherwise idle.

When you use Sound Recorder to record audio in Windows Vista, the recording may contain extraneous noises such as pops or clicks. Or, the recording may sound distorted. This problem may occur when you record from a device that is connected to the line-in port on the computer’s sound card. Additionally, this problem may occur more frequently when Sound Recorder is configured to sample at rates other than 16 bits and 44100 hertz (Hz). This problem does not occur when you use certain third-party programs to record audio.

You try to record audio by using the Sound Recorder application and a microphone in Windows Vista. When you play back the recording, you may not hear any sound.

Note: The microphone in this example is the default logical capture device.
