Mac Mini 2007 and Windows 10 HD Audio Device problem

[Kaida]

Since Apple is showing no love to the Mac Mini 2007, I went with a 128GB SSD + 4GB DDR2 + Windows 10 to see if I can squeeze its last bit of life of this nearing 10 year machine.

I was able to install Windows 10 successfully and got bootcamp 4.0.4033 installed into it. However, I got an yellow ! on the HD audio device with these codes and didn't get any sound on it. Google search shows that it is an IDT Sigmatek and I tried everything I could to get the sound but it was always code 10.

Any experts here has a solution for it?

I had to manually install the sound driver to get audio for my 2009 Mini running Win10. I got it from the vendor website for the chip, not Apple nor MICROS~1.

2009 i got it working from bootcamp drivers. But 2007 I couldn't find it anywhere.

Weird observation:
Sound drivers and infra sensor for remote works when upgrading from Windows 7 with bootcamp to Windows 10.
However, fresh install of Windows 10 and bootcamp (running compatibility mode to Windows 7) does not have the infra sensor nor sound drivers working. Well, at least upgrading works
