Hello John
A friend reports that some of the motherboard sound chips have a configuration bit that turns the low pass filter on or off. I don't know whether your chip does, or whether your driver supports this bit, but these seem like good things to check into. Look at the include file that describes the chip's registers, and/or find its data sheet online by finding the manufacturer's logo and part number on the physical chip, going to their web site, and searching for the part number.
Thanks for that. The IC is an AD1980 from Analog Devices so there is plenty of information around for it. I shall look into this over the weekend. Thanks Again Ian
