Soundcard

All sound has stopped from my Altec Lansing speakers.
I have OS XP s2. The device I believe is the "ATI Function driver for high definition Audio-ATI AA01".
I have tried all the tests in Control Panel/Sounds & Audio and Device Manager. Everything reports as working normally and there is NO mute in any sound control that I can see.
I have plugged the speakers into the headphone socket and still no sound.
I have plugged the speakers into the headphone socket of my radio and they work fine.
I want to try to uninstall the device and reinstall and am unsure of how to do this.
I would appreciate some help or other advice.

FINAL RESOLUTION
My local PC Doctor expert came on a call out.
I was beside myself with frustration, I have spent over a day and a half on this plus all your inputs.
In what seemed like 5 seconds he walked out again leaving me with sound!!
I was flabberghasted and at the same time the proud owner of a new redundant sound card.

In Control Panel/sound and Audio Devives/Audio I had ATI HD rear output selected.
He clicked
Sound Max Digital Audio as the default device
AND IT WORKED.
I had never changed a thing.
I can only assume that during an upgrade of RealPlayer it had altered the default sound somehow.
WELL THAT IS PCs FOR YOU"
THANK YOU ALL FOR YOUR HELP
And to my PC Doctor in Cardiff!

Control Panel - System - Hardware - Device Manager. Remove all sound related entries under Sound, Video and Game controllers. Reboot. Provided the card is not faulty, all will automatically reinstall.

Try changing the sound card position on the main board,,,, try install it on a different slot.
Update the device Driver from the manufacturer website.

Try using Aida or Genius driver Professional software to detect the type of the device, or .

If that didn't work you may try to test the card on a different PC, OR download Bart-pe or knoppix then burn it on a CD, Restart to it. this shall detect if ur sound card is not working.

Dear moh10ly:
I have now successfully uninstalled the sound devices and then rebooted.
The devices installed themselves successfully.
BUT still absolute silence.
I have spoken to DELL upgrades who say my sound card is on the motherboard and perhaps the wire to the socket is detached.
I have therefore ordered a separates PCI sound card and will install that.
I will let you know what happens.
Thanks for your help

That should work, But you may try renaming the current sound card device driver files on your system32 folder, then restart and you will be asked/requested to insert the CD for it.
