It's a brand new system so I've got the choice of either HD or AC'97, I'm using the HD. I've only scratched the surface of the audio software that came with the card but if/when I start to play with it more I'll keep an eye out for something that would cut off the speakers when the FP 'phone jack is in use, just in case. Otherwise I'm happy with the setup I've got for now.
Thanks again for all the input.
