Well if you are unable to install the driver from CD then you should try to install the drivers through device manager.
To open Device Manager, click Start, and then click Control Panel. Double-click System. On the Hardware tab, click Device Manager.
For information about using Device Manager, on the Action menu in Device Manager, click Help.

You can update the driver software for the audio device of your system from the device manager in the Windows XP operating system. For doing that follow the steps given below.
Right click on the My computer icon on the desktop-> Manage->Device manager-> right click on audio device-> select update driver option.
But before doing that make sure that you are connected to the internet.

Hello one day before I was facing the same problem. For some strange reason I had to reinstall my video codecs. And now it works. However, this happened before I even downloaded 5.11 of Winamp, so it seemed strange. The only thing that happened on my PC during my absence made a full scan AVG ... otherwise nothing happened, but it works now. Thank you very much, I will remember to check the properties if it happens again.
