IDT driver XP x64 - HP Pavilion dm1z?

[a10239559]

Can anyone help me to find an IDT sound driver for my HP Pavilion laptop, model dm1z-2100, currently running Windows 7 x64 Professional but which I am looking to downgrade to XP x64?

I posted previously under the guest-name "Audiophile" under this thread, "Michael's New IDT/Sigmatel Modded Driver," before realizing the drivers in that set were for Vista/7 only. Another user, adam777, wrote elsewhere about his disappointment in locating the hard-to-find IDT drivers for XP and not being able to use Michael Marley's collection -- but he was looking to dual-boot, I believe, and I'm not sure if his system was 64-bit. Another thread in which mobilenvidia was doing a project for IDT drivers on XP seems to have fizzled out, but it seems other people have been able to get some of the support they needed for their models, so I figured I would try too. :)

The original post at the thread with Michael's drivers described how I'd previously been able to downgrade to XP x64 with about 95% of luck -- except for being able to use the audio drivers (which I can in Windows 7).

I referenced the "unofficial" downgrade guide from HP Forums here, which does say it's only for 32-bit systems, but my laptop has 5GB RAM and obviously I want to be able to make use of the extended memory that 32-bit can't handle. I tried downgrading once before, and managed to get all of the other drivers to work (SATA, monitor, network, even the webcam, which I don't even use), except for the audio, which is IDT. :(

I also found this link from CNET that someone on another site said has worked for a lot of people, but I'm not sure it will work for me. (Strangely, it's listed under Keyboard Drivers rather than Audio or Sound.) There's another driver that's listed to work specifically with 64-bit Windows, but I'm not sure about this one either (especially since the comments indicate Dell users have downloaded it, with no mention of HP).

I have copied the information about my current audio driver (working under Windows 7 Professional x64), from Device Manager. I'm not exactly sure of what these codes all mean, but with any luck someone may be able to identify and/or tweak a little bit of what I need to get audio working under XP x64.
