Sound card issues downgrading Pavilion dm1z to XP x64? [ Edited ]

[Lovekraft]

A few months ago, while following the "Unofficial Downgrade to XP" guide, I decided to go with XP 64-bit for my Pavilion dm1z laptop. The thread does indicate that 64-bit XP isn't supported at all for newer HP laptops, but I wanted to still take advantage of the expanded memory availability for my laptop with a 64-bit OS. (Specs are below in my signature.)

I was able to get everything working that I needed -- monitor/display, wireless, wired networking, touchpad, SATA drivers -- everything except the audio driver, which HP no longer provides for 64-bit XP and which I was unable to find elsewhere. Upon repeated installs, I would always get "The upgrade does not apply to your system" or something similar. MS UAA HD Audio had installed properly, but audio always appeared with a yellow exclamation in Device Manager. Sound card is used with IDT audio drivers, and I'm assuming that the driver(s) I tried work only with a 32-bit OS. I ended up reinstalling Windows 7 through a recovery USB I had made prior to my attempted downgrade, but am still not happy with Windows 7, and would rather have XP 64-bit.

Can anyone point me in the right direction of either: 1) a guide on how to upgrade/replace the built-in IDT sound card with another, more widely used brand (like Realtek, Conexant or Creative), or 2) somewhere I can download IDT audio drivers for 64-bit Windows XP?

Hi:

Did you try this driver?

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=c02937389&prodT...

I can't pull up the direct download page, but all you need to do is click on the SP53628 file download.

Says it is good for XP x64 in the information section on the page.

Thanks for the link, will try it as soon as I can.

But in case it doesn't work, is it possible to replace the internal audio card with one from another company, and download the XP drivers for that?

You're very welcome.

The audio chip is an integrated part of the motherboard.

Accordingly, it cannot be upgraded or changed.
