For some reason, Windows will install wrong one of that two, but it will download both, so then you can go to device manager and replace it, the Crystal SoundFusion(tm) will be there on the list. And it works just fine for me, I couldn't tell any difference. I get two channel output, but then I only have two speakers on that system. Your mileage may vary, but that is only way I know that works cuz Cirrus Logic abandoned this chipset completely. I doubt there's anything for 64-bit version.
