I forget the exact porting they required, but might bear fruit to investigate that aspect. Ken Hollingsworth Redlands, CA Ken, Device manager does show a yellow question mark by "PCI multimedia audio device" and has no drivers listed for it. I have no PCI cards installed except the modem and video cards so this will be my next mystery to solve! However, I posted earlier that a different modem is now installed and working so that part is fixed.
