Hi Robert, appreciate all the hard work you're doing for us! But I'm having trouble getting the "Audigy-XFI-XP 4.03.00" to work. Right after it's installed (before I restarted the PC) the sound worked great. But once I had restarted it didn't. I tried re-installing and nothing helped. I had just reformatted the PC so no drivers were installed before. The "YouP-PAX-AXv3.63.03d" one works like a charm. Is there anything I/you can do to fix it? BTW, the sound card is an regular Audigy and it's hardware id is: "PCI\VEN_1102&DEV_0004&SUBSYS_00511102&REV_03"
