Using a Dell Precision 360 desktop computer as the product problem,http://www.dell.com/support/drivers/us/en/19/Product/precision-360
,and Windows XP as the Operating System; click on the blue Down Arrow to the left of - Audio (1)
Click on the blue -> Analog Devices - Driver
To the right of File Format: click on the blue - Download File
Under the heading - Choose Download Method, make sure there is a Green dot in the small circle, to the left of -
Single - file download
If there isn't a green dot left-click in the small circle, to the left of Single - file download.
Now click on Continue in the blue oval.
A small window will come up on the right -
Left-click on Save File
Another small window will come up on the left. Allow the file to fully download, then DOUBLE-click right on the file name.
This is a Zip file. You may have to 'unzip' it.
[A Zip file is a compressed file. To 'unzip' it is to 'un-compress' the file. A Zip file is used to send large amounts of information more easily ]
If you have to unzip it go to the far left side. Left-click on Extract all files.
At the bottom of the next 3 small windows click on Next, Next, and Finish.
Or follow the easy instructions if they differ.
(If the zip file opens into many smaller files, DOUBLE-click on one that ends in .exe, or Installer )
After you have installed the audio (Sound) driver, restart your computer, if not asked to do so.
Also look in the System Tray at the bottom of your Windows desktop screen. The Volume icon looks like a little speaker. RIGHT-click on it. Left-click on Open volume control.
Make sure it is UP, and turned ON.
If after all of this there is no sound, turn the computer off normally. Let it sit for 1 minute, then turn it back on.
Still no? Then I suggest the audio chipset is bad on your motherboard. It is Integrated Audio.
Another term for Integrated is OnBoard.
ON the motherBOARD.
If your OnBoard Audio is bad then I suggest a Sound Card. There are economical models out there, that will make your integrated audio sound like a tin can.
