I had a new dard drive installed and the sound worked fine for about 3 weeks but I kept getting a message saying new PCI device but it wasn't able to locte software by internet or on driver discs or XP disc, This may have no connection?

Now there is no sound at all (the speakers have been checked and work)

There used to be a SoundMax control panel, but there is now only an icon with a red circle and diagonal line across the icon.

When I check control panel, sound and audio devices, Volume tab; it says "no audio device"

Under the Hardware tab all of the deviosces listed show as working properly.

Can anyone offer advice please?

Many thanks
