Ahh relief at last

I did a search and found this from the user BillyHunt here:-
"Finally I have done it
For anybody else that might happen to be as stuck as I was here's what I had to do.
1. Choose Start > Control Panel and double click Add hardware, then click Next.
Click "Yes, I have already connected the hardware" and click Next.
2. Choose Add a new hardware device at the bottom of the list and click Next.
Select "Install the hardware that I manually select from a list (Advanced)", and click Next.
3. Select "Sound, video and game controllers" from "Common hardware types" list and click Next.
Select "(Standard system devices)" from "Manufacturer" and click Have Disk.
4. Click Browse in the "Install From Disk" dialog box and open the folder C:\Windows\System32
Find mmdriver.inf file, select it and click Open then click OK in the "Install From Disk" dialog box. If you see a warning about logo compatibility, just click "Continue Anyway".
5.Scroll down the list and select "Microsoft Audio Compression Manager" click next
6. Reboot"
This worked a treat, all my sounds are now back. Anyone else with this problem - this should fix it.
