If you don't hear any sound from your computer's speakers, it may be because the computer's hardware volume control knob is turned down. Both the Recording Volume and Playback Volume indicators should move up and down in response to sound picked up by the microphone. You should hear whatever sounds you make in the computer's speaker(s), after a brief delay. Speak into the microphone, or gently tap it.
Click the Next button to test the speakers using the microphone as the sound source. The Recording Volume indicator should move up and down in response to sound picked up by the microphone. When the Microphone Test window appears, speak into the microphone, or gently tap it. Wait a minuter or two for the wizard to complete tests of the internal sound hardware. In the Sound Hardware Test Wizard window, click the Next button. Click the "Sounds and Audio Devices" icon. Click the category "Sounds, Speech, and Audio Devices". Start the Windows Control Panel (Click Start, then Control Panel). 
If it's not already checked, check the Select box for the microphone channel. Move the volume slider for the microphone to roughly the midway position. If it's not already selected, select Recording (under "Adjust volume for"), then click the OK button. In the Master Volume (Control) applet, click Options, then Properties. 
Click Start, then All Programs, Accessories, Entertainment, Volume Control. If not, then plug an external microphone into the microphone input jack. Determine, from the User's Guide, whether or not the computer has a built-in internal microphone. 
However, most of the sounds from Windows 7 remain in Windows 8.For Windows XP, follow these steps to test the computer's sound hardware, including microphone and speakers: Windows 8 once again replaces the default sound scheme. The sounds from early versions of Windows are also updated in these versions. The early Windows sounds (as they appear in Windows 2000) are also included.Ī similar scheme of sounds is included in Windows Vista and Windows 7. In Windows XP, a completely new scheme of default sounds was introduced. Sounds added in newer versions were added to the default sound scheme along with existing ones. These sounds are the default sounds in early versions of Windows.
