Hey Alan
For £1.50+ per minute I will call you myself
....sorry to hear you had to go through that......
Here is thing.....The Belac program does not report the hardware properly...I have looked at your initial post...if you look you will see that is says "Sound Blaster 16 or AWE32 or compatible (WDM)" that throw me out ...but looking at it more carefully I can see that your Motherboard is Intel 915G chipset family:

Download and install the Intel Chipset utility first.
Then download Realtek driver from this site:

Hope this fixes your sound issue.
