|I'm wondering if we might have a terminology problem:|
On-board sound module is a chip on the motherboard - usually provided from new.
Sound card is an add-on circuit board, which is used to replace the on-board sound module. It might need to be switched over in BIOS.
Sound driver is software that is required to make either of the above function properly. This can be on a disk or downloaded. It has to match the module or card.
Always pop back and let us know the outcome - thanks
