XP Networking

Hi Folks,
I have two computers on XP. Network connected by an ethernet router, with NTL Broadband installed. Since the router and NTL broadband have been installed, both computers have no sound. All systems are working with all Drivers working and best available. I cannot hear CD's or hear any of the media players playing. NTL have no idea how to fix the problem. I cannot reinstall guest computer sound card drivers as they are on a HP Windows ME all in one disk which came with the computer, and I'm now on XP.
Any replies, please make them very simple as I have very limited computer knowledge.
Any ideas
Cheers
touchline.

 

Did the trouble begin after you acquired broadband, or after you switched to XP?

Check the device manager (R click My Computer on your desktop, L click Properties. Click on the Hardware tab, then the Device Manager button. Click on the "+" next to Sound, video and game controllers. Tell us if you se any !'s or ?'s)

You have a few options depending upon what you see.

 

Try this: Go to Control panel/Sounds and audio devices.On the Volume tab,click Advanced,make sure nothing is muted.
