Thanks for replying, dell4700.
Volume control was the first thing I checked, it's not muted.
In my control panel, there is no 'Sounds and multimedia' properties, only 'Sounds and audio devices', which I checked before.
Where is the device manager? Didn't see that option in my Control Panel. I'm in Malaysia, if that makes any difference... would there be different software versions to be so different?
The thing is, I can play music CDs (or music copied to my hard disc) but when I try an interactive CD, there is no sound at all. And even when the Sound Scheme is Windows Default, I cannot hear any of the windows Program Events sounds, even when I select and play one from the list in the Sounds Properties.
I cannot understand why it can play some sounds but not others., when we did not change any of the settings.
Thanks in advance for any more help...
