I just installed Windows XP Professional x64 Edition on my HP Pavilion dv6000z CTO notebook. I got everything to work except for sound. I looked everywhere for Conexant High Definition Audio drivers and couldn’t find anything. I tried the ATI Digital Audio trick and that gave me a “code 10” error. Any other suggestions? I’m really getting frustrated with the whole x64 thing..
The driver is located here.
Thank you for your help, but will that work with XP 64-bit? It only states that it runs in XP Home, Pro (32bit), and Media Center Edition. I’ll try it and see what happens.
It turns out that I ditched the x64 junk. I just bought Windows Vista Home Basic 32bit and it works a lot better than XP 64 bit. Plus, the sound works. 
Yeah, in fact 32-bit is more supported that 64-bit at the moment. But that’ll change in the future.
