Windows XP - IDT HD Audio Device Code 10

[squall leonhart]

Refuses to work with Windows Update drivers as well as official Sigmatel drivers.

That is exactly why HDA isn't the default audio device for XP guests. The drivers from Windows Update don't work with the SigmaTel codec even on real hardware, and at any rate XP comes with drivers for AC'97 but not HDA. Even if it did work, there is currently no benefit XP guests could derive from using HDA versus AC'97, only hassle.

[squall leonhart]

That is patently False.

I have used Sigmatel Codecs with windows xp in the past just fine, the implementation of the emulation is that which is at fault, not the OS.

The device ID that is emulated, specifically has windows xp drivers available.

[michaln]

What is "patently false"? The fact that HDA on XP requires separately downloadable drivers that aren't part of the base OS, while AC'97 doesn't?

[squall leonhart]

The drivers from Windows Update don't work with the SigmaTel codec even on real hardware, and at any rate XP comes with drivers for AC'97 but not HDA.

The drivers are specifically IDT Drivers for the device specified.

Shortly speaking - HDA device emulation doesn't work with default XP drivers yet. We don't consider that too important, as AC97 works.
And please, dear Leonhart, stop trolling. If you have ideas where our emulation is faulty, please share them, although according to our experience, drivers shipped
with XP by default indeed doesn't work with many HDA card.

What part of "The drivers are specifically IDT Drivers for the device specified" constitutes trolling?

Windows does not install any drivers for the device by default, it connects to Microsoft update and downloads the required IDT ven_8384&dev_7680 drivers required, which do work on the specified real hardware on a D945GNT.

The driver that does not work with our HD Audio on your XP doesn't work either on a physical system having that very HD Audio (+ CODEC) chip (we actually verified this). Virtual hardware exactly emulates the behavior of physical hardware so we're doing our job here. The bottom line is: don't choose HD Audio for XP.

i had the same driver working on my friends Intel mainboard, with the emulated hardware, but it could be a problem of implementation on the mainboard. i've seen 2 revisions of the same chip share a dev id before but requiring different drivers.

Is there a source for any sigmatel driver that actually works on XP or do none of them work?

Dude, did you ever consider that the hardware put in that machine is NOT THE SAME as the HDA we're talking about here? There are various implementations of the hardware and IDT has one of them. They are NOT compatible. I repeat, drivers from one implementation DO NOT work on the other. If you want to verify it, search for the IDT HDA specifications and compare it to Intel's. Oh, wait, that might not be possible because IDT doesn't provide technical specifications of their hardware that easily.

don't use the same Compatible ID if its not a compatible device.

Could you please run http://www.alsa-project.org/alsa-info.sh on your friends Intel mainboard and attach the output here?

It's more complex than you can probably imagine. The PCI audio controller (Intel HDA) can be the same but the separate CODEC chip might be very different on two systems. Thus you need the right driver for that combination. It's hard to understand in Windows because all you see is the audio controller but it's the CODEC that is important here.

I've read this thread and concluded, that HDA audio should work if I would use the driver/codec for my hardware (Dell Latitude E6400).
This is not the case, the driver doesn't even install. Other drivers are installable but then I get the same error code. Where am I wrong? Or is it a no-go to use HDA with XP?

My configuration:
Host: Ubuntu 10.04 64 bit
Guest: Windows XP SP3

Thanks

From Dell site it isn't very clear which codec on your model, to simplify guess you can post output of http://www.alsa-project.org/alsa-info.sh script here.
