Intel said they no longer have a relationship with IDT, so I doubt they will be providing an official fix for the audio drivers.

Glad you've achieved a resolution now but did you ask Intel tech support for newer IDT drivers (perhaps even unsigned ones)?

Additionally, I see others have complained in this forum about the power LED header issue - looks like its time to hurry up and wait for yet more fixes from Intel

After a lot of back and forth with Intel support, they have decided to send me an upgraded motherboard and processor instead of fixing the audio drivers for the DP45SG. I have a DP67BG now, which uses Realtek audio, and I have had no problems whatsoever with the optical S/PDIF output. The power LED connector doesn't work, but I am officially being ignored by Intel support now.

I used to think Intel was synonymous with quality, but this experience has taught me otherwise. I will definitely think twice about purchasing Intel products in the future.

This is an issue with these motherboards when the optical (TOSLINK) Audio output is used. If you only ever use the analog 3.5 mm sockets, the problem will not occur anyway - switch over to using the optical output though (perhaps in the future when you buy a receiver capable of handling such audio signals) and you'll definitely experience the issue (probably within a minute or two of using the audio in my experience).

The best way to fix this is with new drivers. Clearly, drivers that fix the problem have already been developed so why isn't Intel simply getting the latest IDT CODEC Drivers digitally signed and putting them up on the website for all to access. Dell and HP are looking after their customers with the latest CODEC drivers but Intels customers are being left out in the cold unsupported over this problem.....

These boards are getting long in the tooth (even though they've not all reached 'end of life' support status). The hard work has already been done and we are already so close to acheiving what we need to resolve this but Intel needs more encouragement from those with these boards to take these final steps and release a new driver package. emirwati and anyone else with the DP45SG, DG45ID or DG45FP please get in touch with Intel right away and protect your PCs functionality for the future (for when you do buy an audio solution or headphones capable of handling optical inputs) by asking for these new drivers to be released to Intel customers - before its too late.

I think that you can overcome the fault by having a headset plugged into the front panel at the same time that you have the speakers connected to the rear panel. It seems that sound is not hanging in my case with that combination.

You've taken the time to provide a detailed response with all the steps you took to get a working solution - thanks. I will try this out and report back!

You should be aware that this is NOT associated with a Dolby Digital Live issue however and the very old Intel release version Vista Driver from 2008 (that was on the FTP site and was referred to earlier in the thread) still has Dolby Digital Live capability built in and THIS works great on my Win 7 SP1 x86 PC (but without any mute capability). Somewhere between that version and current versions it looks as if Intel/IDT made some changes to the underlying core drivers which result in the audio lock-up problems and the subsequent lack of ability to select Dolby Digital Live again immediately after this problem has arisen.

It is old hardware but more and more people are buying optical capable audio solutions these days and hooking up their PCs for the ultimate HTPC experience. It's therfore important that all of the Intel boards which use this IDT codec (and there are at least 3 of them - don't forget the DG45FC) have reliable drivers which don't lock up when using the S/PDIF optical port. If IDT have even newer core drivers than those included in the Intel package, drivers that don't exhibit these problems then why aren't Intel being fed such updates when other hardware providers are? I'm off to do some testing - I guess my ideal would be to try that full Dell driver package with my DG45ID but I don't know (haven't figured out yet ) what bit(s) of the Dell driver package stop it from installing on the Intel motherboard.

Solution:

I did find a solution that worked for me. Here is what I ended up doing:

Download the updated driver for IDT 92HDxxx HD Audio for Windows XP/Vista/Win7, x86 and x64 from Dell. This driver is almost a year newer than the Intel driver.

http://support.dell.com/support/downloads/download.aspx?c=us&cs=08&l=en&s=bsdr&releaseid=R297613&SystemID=LAT_E5520&servicetag=&os=W764&osl=en&deviceid=16105&devlib=0&typecnt=0&vercnt=2&catid=-1&impid=-1&formatcnt=0&libid=3&typeid=-1&dateid=-1&formatid=-1&source=-1&fileid=446749

When you execute this install package it will extract to C:\dell\drivers\R297613

Also, download the latest driver from Intel, it will extract to \AUD_ALLOS_6224.7_PV_IDTGUI_V186

Copy the following files from the Dell driver over the files in the Intel driver directory.

setup.exe
Setup.ini
setup.inx

Copy these files from the \WDM\Vista sub directory Dell driver into the \WDM\Vista sub directory for the Intel driver :

IDTPMA64.exe
stacsv.exe
stacsv64.exe
stapi32.dll
stapi64.dll
stapo.dll
stapo64.dll
stlang.dll
stlang64.dll
sttray.exe
sttray64.exe
stwrt.sys
stwrt64.sys

Then install the Intel driver using the newer driver.

I'm currently using Windows 7 32bit as an operating system, but I have no reason to think that this would not also work for Vista or Windows 7 64 bit.

Here is what I believe this does:

Microsoft provides an API into the sound system with audiodg.exe in Windows Vista and Windows 7. The driver plugs into this API to provide Dolby Digital encoding. The older driver does not have Dobly Digital Live so it doesn't hook into the API and does not experience a problem. I really like the Dolby Digital Live feature because it encodes audio streams as Dolby Digital even when they are stereo. It also passes the Dolby Digital stream through if it exists.

The IDT 92HDXXXX codec is used by a lot of different manufacturers for their audio processors. IDT however does not provide drivers to end users, so there is no way to get a newer driver from them. Intel has moved on to newer boards and harware and don't need to get updated drivers from IDT. (Though they should since thier version has a bug) Dell has released newer hardware based on this codec and therefore has purchased or licesnsed newer drivers from IDT to support them.

The Dell driver as well as the Intel driver includes INF files that specify which hardware the driver is designed for. When you try to install the Dell driver, it sees that your hardware doesn't match and won't install. By copying the actuall DLLs over to the Intel driver but not the INF files, the Intel driver installation package works as expected. I believe the actual hardware is the same and the driver is compatible. My testing with the newer driver and software confirms that assumption.

Intel could go back to IDT and get the updated driver, but I don't know that there is really a motivation for them to do so. We are dealing with an end of life product here. All of this is my own theories and as such should be taken appropriately. I make no garuantees and Intel certainly won't support using a Dell version of the driver on Intel hardware.

Here are some supporting links to what I've discovered:

Then it's doubly important that this problem be resolved for you. If you haven't already done so, it'd be worth creating a ticket (or tickets) about the issue with Intel (preferrably for both boards).

The description of what that service is all about reads "Manages audio jack configurations." so perhaps it has something to do with jack retasking? I've gotten rid of the current drivers in favour of the one linked to earlier in the thread. This service is present on the system after loading this driver and as there's no lockups when using this driver (at least on my DG45ID), I've not been able to verify what you write. I have tried a driver which had no Dolby Digital Live button or configuration options on it at all and that still locked up like the current drivers so I'm not sure this is the problem.

I suspect the lock-up bug has something to do with changes made to make the drivers Windows 7 compatible but as there aren't a large selection of drivers to try on Intels website, I can't say between which specific versions the problem cropped up. I think if I was an engineer trying to resolve this problem, aside from reviewing the changes as above, I'd be looking to work from the version I'm using and add working mute and identifying when SPDIF is actually being used and reporting that to the OS. Maybe it's possible to test the older core drivers within the driver I'm now using, with newer GUI related bits like the control panel. That would help to weed out whether the issue is in the core drivers or the 'frilly bits' that go with them like the GUI/Audio Control Panel - my hunch is the former!

If you're using a DP45SP with the SPDIF output as the only audio connection Ray, would you be kind enough to test the original CDROM drivers linked to earlier in the thread (on post 70) and see how they go with your board. Audiophile complained that they still locked up with his DP45SP but they've totally fixed that issue for my DG45ID. I've included a screenshot of the audio driver GUI with version details accessible by clicking the questionmark. I've circled the jack I'm actually using but alas this driver (nor the current one) doesn't indicate that TOSLINK port is selected and I don't think it reports this to the OS either as my iMON LCD doesn't illuminate the SPDIF icon (iMON is controlled by what the operating system sees).
