Na buddy....the on-board sound was removed the moment I installed the card. I didn't have to install it's drivers for it to kick off the on-board audio. It's happened to a few HP Compaq dc7800 machines. I tried enabling the sound via BIOS, I tried downloading the official driver but was always requested to download a management app or was blocked by security. I've tried copying to registration and allowing but still negetive. It works for the HP Compaq dc 8100s, unfortunately the 7800 don't like the card for some reason.
I've resorted to imaging on a 8100 instead. didn't want to waste time on it too much but it would be handy to know if there is a way around this issue.
Thanks alot for your contribution I'd be glad to answer some of your IT issues as well. When I'm free that is. I pop in every now and then.
Cheers.
