I'm trying to find out how to get the sound on my computer to work again. I used to have windows 2000 and the sound worked fine... now that I have installed windows xp... no sound. Help!

I hope this is helpful. This info is from computerhope.com.

Windows XP

1. Open the Control panel

2. Open the "Sounds and Audio Devices" icon.

3. Verify the "Place volume icon in the taskbar" checkbox is checked. If this option is not available or is grayed out, skip to the next section of this document.

4. If you were able to check this box, click OK and close out of this window and the Control Panel.

5. Double-click the sound icon in the systray and verify that all the sound volumes are mid-way or higher.

If this doesn't work, try this. This is to verify your installed drivers:

1. Open the Windows Device Manager

2. Verify there are no conflicts or errors listed anywhere in Device Manager. If conflicts exist skip down to conflicts section.

3. Verify no other devices are listed. If other devices are listed skip down to other devices section.

4. Verify that your "Sound, video and game controllers" category is listed, if not skip down to the missing sound card section.

5. If no conflicts or other devices are listed and your sound card is listed with no conflicts, skip to the next section.

Here is the website if you just want to refer to there: Missing or lost sound in Windows 95 / 98 / ME / 2K / XP.

I think your sound driver can only work in 2000, not in xp.
The only way, you must install audio driver software

I think you need to download drivers for XP, try this link >>
