Does Device Manager show the card? If so, and you have sound from external speakers, you have a hardware problem.
Look again at Device Manager and the sound properties.
BTW, there is no Pro/Home XP. It's Pro or Home.
Wait, I'm confused. Which speaker(s) do you want to use?
I have installed after buying a Windows XP Professional Home Edition.
I previously had a pirated version installed on my computer. After intalling I have NO sounds. I have an old Creative Sound card. Computer states that there is NO sound card installed.
What can I do to get sound back. I do hear sounds from the speakers, but no sound coming from computer with you tube etc.
Thanks for your help.
