Wonderwrench et al,
Yes, the Wiki bunch are pretty adamant, aren't they, that the UAA driver is contained within SP3 for XP? Here's the bit from Wiki:-
In 2004, Microsoft provided the first version of UAA as an update to Windows 2000 Service Pack 4, Windows XP Service Pack 1 and Windows Server 2003, but is only available by contacting Microsoft support directly.[2] However, almost all manufacturer supplied drivers contain the UAA class driver. Windows XP Service Pack 3 also includes the updated driver.
I've done several reinstalls of my current system in the last few years, adding SP3 each time, and I've never encountered this UAA requirement before or during that process. For this new Gigabyte board I'm getting, it looks like it's not needed if SP3 is going to be installed. Perhaps the situation is slightly different if, for some reason, you're using XP SP2 only, or Vista or Windows 7? The only caveat would perhaps be if the version in SP3 was now out of date.
Yes, Wonderwrench, I'll have to suck it and see. With the new board, I'll not attempt to install it, and then see how the sound card and audio streaming fair. I too use an imaging backup system, which I use as I build up the software, so I can certainly test in the manner you've described. I strongly suspect I'll not need to do so, though. That said, the implication is that the UAA driver has ideally to be loaded early on in the installation of the system's software, ie. directly after the OS has been installed. So, if it isn't in SP3 and I miss that slot, ie. not separately add it at around the time of installing SP3, I may have a long way to go back, in terms of images. Perhaps I'll just have to install the Creative driver earlier than I normally do.
Actually, I've been wondering whether, for this particular Gigabyte board, the Realtek PCIe LAN driver v.5.7.64 is even required. The GA-P55-US3L has a built-in wired Ethernet port and so unless you want extra Ethernet porting on it, there's no need for a separate PCI or PCIe network interface card. In my current machine, which doesn't have built-in Ethernetting, I've been using a PCI nic, and that certainly didn't require a special driver for me to install. So, I suspect that any driver it needed was already there, in WinXP or in SP3. Logic would therefore now lead me to the assumption that the Gigabyte board will also not require an Ethernet driver to be added, ie. that Realtek PCIe LAN driver will not be required. What d'ya reckon?
