Troubleshooting Your Computer Troubleshooting Techniques If sound does not record • Check the software controls for recording sound: click Start, Programs, Accessories, Multimedia (or Entertainment), Sound Recorder. • In Volume Control, click Options, Properties, and make sure the microphone is enabled in the recording controls. • Test the audio with the e-DiagTools diagnostics-see "Testing the Hardware" on page 162. If you hear a loud high-pitched whine (feedback) from the speakers • In the Volume Control, try reducing the Master volume: double-click the speaker icon in the taskbar. • In Volume Control, click Options, Properties, and select the microphone option for the playback settings. Then in Volume Control, make sure the microphone is muted. • Avoid using the built-in microphone and built-in speakers at the same time.
