DP45SG IDT audio driver hangs?

I am running Windows 7 64-bit on a system built with a DP45SG desktop board.  I am trying to use the on-board rear S/PDIF connector to send audio to my receiver.  Installing the IDT audio driver is the only way I have found to get this working.  After installing the driver, the audio will work for a short time, but it will eventually stop working and cause any application that tries to play audio to hang.  This includes windows explorer, when it tries to play a logoff sound, for example.  Often, rebooting the system will fix the problem but not always.

 

I have been unable to figure out what causes the audio driver to hang.  It has never happend during audio playback, but it seems to be triggered when playback stops.  For example, sometimes I will close the web browser while a video is playing, then any application that tries to play audio after that will hang.  Other times it seems to happen randomly.  I have tried several supposed workarounds mentioned on other sites, such as installing the driver in Vista compatibility mode and disabling audio enhancements and system effects.  As far as I can tell, none of these have had any effect.  All my drivers and BIOS are up to date.

 

After searching the internet, it seems that many people are having a similar problem.  Has anyone discovered how to fix this?

    Yep, me too.

     

    I think it might just be cheaper to purchase a new sound card, but I'm pretty ticked off that I'm NOT the only one with this problem and no fix is available.

    I guess I got a flakey board- did a clean install from vista64 to win7-64 and really, its a whole lot worse on 7 !!! Grrrrrrrr!

    Closely monitoring your usage might avoid problems or installing a sound card.  I am considering a sound card myself since I'm often preferring analog FM to on-line 44.1 kHz, even when analog is mono, but it's difficult to justify.

    My last issue seemed to occur when I changed optical out to local speakers while online.  The IDT system may have memory leaks. There seems to be a difference in buffer used by different programs.  Windows Media Center sound will continue after closing but I haven't noticed this with on-line radio.  If you are using IE9 now you may have fewer problems since it behaves better.

    I'm soooo glad I found this post! Don't worry,this is my experience with these IDT/Intel drivers on a similarly equipped DG45ID too and I'm glad to find others confirming it. There is a solution (although not an ideal one). Uninstall the IDT drivers altogether and upgrade your Win 7 installation to SP1. The native Win 7 SP1 drivers do NOT have this locking up problem and they will still play Dolby Digital files eg AC3 files played through Windows Media Centre with full surround (5.1 or 7.1 etc) sound - it's just you don't have the option to convert ordinary stereo into this format so regular Windows things will still play in stereo. Clearly there's an issue with the latest IDT drivers though so it'd be worth reporting this to Intel so they can in turn report it to IDT and ask for a solution to be developed!

     

    If you want to test the Microsoft drivers to make sure they're working in this way properly do this:

    1. Click the volume icon on system tray area
    2. Click the black 'digital audio' box at the top of the mixer
    3. A Digital Audio Properties window will open up
    4. Click the 'supported formats' tab
    5. Ensure the Dolby Digital tickbox has a tick in it and the correct frequency for your receiver is selected (in my case 48 KHz)
    6. While 'Dolby Digital' is selected/highlighted, click the test button
    7. Listen to the glorious Dolby Digital sound output and click yes to the box that pops up afterwards asking if you'd heard it!

     

    Playing a suitably encoded DVD/HD-DVD or Blu-ray etc using an appropriate player (I'm using Arcsoft TMT 5) will also exercise the Dolby Digital capabilities without locking up any mixers/audio software or causing problems.

     

    This is one of those rare situations where the native Windows drivers are MORE reliable than the motherboard manufacturer provided ones. It's just a shame that they don't have the 'bells and whistles' of the IDT drivers.

     

    I hope this answers your question!

    I have Windows 7 Service Pack 1 installed, and I cannot get any audio from the S/PDIF connector without the IDT driver installed.  Without the IDT driver installed, I do see a "Digital Audio (S/PDIF)" device in the Windows playback devices dialog, but it fails to produce any sound when testing any encoded formats or sample rates.  If I select it as the default playback device, the audio indicator bars on the right side will light up when a sound is played, but I never hear any sound coming from the speakers.  With the IDT driver installed, sound comes from the speakers, but it also causes application hangs.  I would gladly give up the IDT "bells and whistles" just to get audio from the S/PDIF connector without application hangs.

    So you have the Digital Audio (S/PDIF) driver version 6.1.7601.17514 installed and no exclamation marks in Device manager (and you've powered off and on again after uninstalling the IDT drivers)? What receiver are you using and how is it connected? How are its speakers connected/configured? What frequency does the receiver require the connection to be at and do the settings on the properties I referred to above match this (on my setup initially DTS was selected so I had to change it to Dolby Digital). How did the test I referred to above go (or is that also a no sound emmitted result)? While the sound was being 'displayed in the mixer', what lights were displayed on the receiver? Mine has a Digital Input light which is illuminated whenever the fibre cable is plugged in and two other LEDs Dolby PL II when stereo comes through or this switches to Dolby Digital when 5.1 or 7.1 comes through. It could be something as simple as the receiver volume being turned right down or muted....

     

    You do realise that the receiver must support Dolby Digital if you're using this board don't you - other 'surround sound' technologies such as DTS are not supported by the IDT chip. My receiver is for a Turtlebeach X41 wireless headphone set and it's plugged directly into the optical port using the supplied TOSLINK fibre cable.

     

    Sean, how does this solution work for you?

    I've been setting up to try the Win 7 alone and found out the IDT seems to mostly offer an option for using the desktop speakers for telephone service, possibly simultaneously with optical out.  I don't see how to set this up with Windows but to see what I'm talking about set up the optical out with either Windows or IDT panels then change the IDT panel to use local speakers.  Go into the windows panel and change back to SPDIF optical.  Now the SPDIF is checked for default but the desktop speakers have a telephone icon.  That can be deselected in Windows.  Maybe I can find a manual for the IDT.  My old dial-up modem and multipurpose printer provided for this. 

    Otherwise the IDT seems to offer Dolby base and space expander for the desktop.  Equalizer shows base enhanced but not very detectable for my little Altec Lansings.  Space expansion is noticeable and impressive, doubling apparent separation.  Enabling dolby gave me stereo and much improved audio for optical out for radio.

    The image I created should allow very fast recovery if audio uninstall messes up too badly for system recover but I wonder if it might be best to disable the desktop speakers when using optical out.  This could affect the other option of allowing application control that may be the big problem.  Still uncertain if my online switch of audio output led to problems a couple days later.  The old problem I had was computer couldn't shutdown without playing sound but adding speakers fixed this with a 9600GT.  I should have disabled the speakers.

    No manual I'm afraid, just the programs own help. What do you mean by the desktop speakers have a telephone icon? If I connected my corded headphones to the regular speaker jack while outputting sound via S/PDIF to my Dolby Digital receiver, this didn't happen with mine. It's all a rather moot point now anyway though because as I and others here have found (and no doubt you will too, if you attempt it) outputting Dolby Digital using the IDT drivers is a recipie for sound software lockups galore. The Microsoft ones are the only way to go at the moment (reserving judgement in case Intel/IDT do actually fix this problem with their drivers in the future).

    That confirms my suspicion the green telephone icon for speakers in addition to green check for optical must be a bug.  This is disturbing since that should only occur if there is a program that can employ that.  Even if a fax machine were present and telephone for speech + fax were intended I'm not sure this is the way it should be either.   Virtual PC is of no help for viewing w/o IDT so I trust I'll be removing the IDT from regular machines.  Any problems with the IDT seem to be for other than desktop speakers but I would as soon use the Windows drivers.  I haven't been using Dolby but did notice an error on my receiver after closing online radio with Dolby.  I have trouble discerning at this time what problems are due to monitor, Vista or IDT since they have generally been minor.  Maybe I'll go retro and merge the Vista and XP machines.  OK.

    If you're referring to either TAD (telephone answering device) or Speakerphone functionality (a seperate function which some voice capable modems are capable of) then that's correct - there still should be no mention of this (at all) in there. It sounds like your system has become mixed up and confused (well as much as a PC can be anyway ). As mentioned, uninstalling the IDT drivers and resorting to the newer Microsoft Win 7 SP1 High Def Audio ones will restore reliable Dolby functioning and you won't have to worry about the wrong things being displayed here.

    Yes.

     

    What receiver are you using and how is it connected?

     

    Sony STR-DG520 connected with TOSLINK cable.

     

    How are its speakers connected/configured?

     

    5.1 surround.

     

    What frequency does the receiver require the connection to be at and do the settings on the properties I referred to above match this

     

    The receiver supports Dolby Digital and DTS decoding at 44.1kHz, 48kHz, or 96kHz.  Yes, the properties match this.

     

    How did the test I referred to above go (or is that also a no sound emmitted result)?

     

    No sound emmitted.

     

    While the sound was being 'displayed in the mixer', what lights were displayed on the receiver?

     

    Nothing displayed on the receiver.  The front panel will show what channels are active when it is receiving a signal, and there is nothing.  It looks like there is no signal being sent.  When the audio was working with the IDT driver, the TOSLINK cable would be emitting a red light if I unplug it.  In this case, there is no light at all coming through the TOSLINK cable.

     

    It could be something as simple as the receiver volume being turned right down or muted....

     

    I checked all the settings on the receiver, and everything looks fine.

     

    You do realise that the receiver must support Dolby Digital if you're using this board don't you - other 'surround sound' technologies such as DTS are not supported by the IDT chip.


    The receiver does support Dolby Digital and worked fine with it when the IDT driver was installed.  I am thinking the DG45IG may have a different IDT audio chip that works with the Windows driver.

    If you have installed software specific to MP3/WinAmp or RealAudio they may contribute to the problem.  I've only used Windows Media (WAV) files but am considering these for live, not recording.   The logoff problem I had was due to speakers having been present during installation.  The nVidia solution, since this was with a 9600GT w HDMI, coupled with a Dell U2311 with DVI and display port but no HDMI input can be found below.  I simply added speakers.  The control panel shows only IDT HD CODEC but sound works.  A 240GT with the newer 3D capable drivers shows 4 nVidia HD drivers.  This likewise has unused HDMI with DVI to U2311.  Problems are limited to infrequent recording attempts with a TV tuner.

    I stop playback in Windows Media Center before closing to avoid any threading and hard drive write problems.  The Buffer size can also be changed.  Uninstalling audio seems safe and this is required to install an update.  I'm not sure about sound cards.  One test of the icon issue seemed to differ from previous experience.  I'm making sure to have only the one output enabled in Windows sound panel and only using the IDT panel to enable Dolby initially.  This system has only Intel graphics.

     

    The nVidia forum response was

    Certain computer motherboards which feature an onboard audio controller will disable the onboard audio controller if it detects the presense of another audio controller installed in your PC. Newer NVIDIA GPUs such as the Geforce G210, Geforce GT220, etc. feature an onboard HDMI and DisplayPort audio codec. This allows the graphics card to send audio as well as video to a connected display via HDMI or DisplayPort if your display can receive audio through these inputs and if your graphics card came with either of these display outputs. Even if your graphics card does not have a native HDMI or DisplayPort connection, if the PC detects an NVIDIA audio codec on the NVIDIA GPU (Graphics Processing Unit), it may still disable the motherboard onboard audio controller. To correct this, you will need to go into your motherboard BIOS and change the setting "Onboard Audio" from "Auto" to "Enabled". This will force the onboard audio controller to always be enabled even if there is another audio device present in your PC. If your motherboard BIOS does not include this setting, check with your PC manufacturer for a newer motherboard BIOS which may add this option.

    Thanks for checking that - it's a useful thing I didn't think to ask you to look at. On my DG45ID the red light is there at the end of the fibre whenever it's powered up so clearly you are right in that it appears to be (at least) soething on the PC side which isn't right.

     

    The DG45ID has just the one audio chip which is used by the IDT or Windows drivers. There's no switching over to a different chip. Do you have any additional audio cards/devices plugged into any of your your motherboard slots or USB ports? Do you have a discrete graphics card plugged into the board, esp one with HDMI capability?

     

    The Microsoft version of the High Definition Audio Device drivers are Universal Audio Architecture type which don't give the same depth of control as the IDT ones, that said, if not configured correctly, audio won't work (and there'll be no read light out the end of the TOSLINK cable). Does this look familiar?Sound control panel.jpg[Edit: One additional thing, although your receiver may support high frequencies like 96 KHz, I don't know if the IDT Chips does so it'll pay to ensure JUST 48 KHZ and JUST Dolby Digital are selected in the Digital Audio (S/PDIF) device Properties here]:SPDIF Properties.jpg

    I do not have any other audio devices, but I do have a discrete graphics card.  My graphics card does not support audio and only has VGA and DVI connectors.

     

    My playback devices dialog looks exactly like your screenshot, except my speakers are connected.  As a test, I unplugged my speakers, but I was still unable to get any audio from the S/PDIF connector.  I am curious as to why the dialog shows an HDMI device when there is none as far as I can tell.

     

    I tried changing the supported formats to match the ones shown in your screenshot but still no luck with the Windows driver.

    Here is the variation obtained where SPDIF was selected in windows then changed in IDT panel. May be different when both open simulaneously.

     

    Sound.PNG

    No graphics card

     

    DevManagerSound.PNG

    Abnormal  below with 9600GT

     

    DG45ID9600GT.PNG

    This has stereo so I never retried reinstallation.

    Perhaps uninstalling the graphics card, shutdown to remove, uninstalling audio, restart, latest INF if not present, install audio, shut down to insert card and install graphics driver?  Probably this HDMI is too old.
