    DG45ID WinXP IDT audio driver High latencies

    irus

      i'm using the onboard audio of  DG45ID/ AA E27729-312 which is IDT high definition audio on Windows XP professional SP3 and the audio drivers are not functioning properly (version 186) . The audio drivers are introducing a lot of DPC latency as observed in DPC latency program while playing music or even with normal windows OS sounds.

       

      All drivers, bios, windows hotfixes/patches are upto date.

       

      What could be the problem??

       

      Thanks.

          The DPC Latency program itself.....

           

          Other than this program that tells you there's a problem, is there any actual problem you are experiencing with audio, if so what is it and what audio connection are you using out of the PC? How does it work with just the drivers on a Windows XP SP3 setup without additional audio or diagnostic software?

           

          The DG45ID is a very mature board that's been out for a long time so what changes did you make to the system that precipitated this behaviour/result? Although I briefly had Win XP on my DG45ID, I quickly upgraded to Win 7 when I realised that there is no Graphics Driver support for the full HD Graphics acceleration under XP (eg for Blu-Ray or HD-DVD playback), this is only avail with the Vista or Win 7 drivers.

            the only external device attached to the motherboard audio system are my audiophile quality headphones. The DPC program doesnt show any problems in windows 7x64, so i assume the problem is winxp sp3 x86 audio drivers. In real world scenario i get slight skipping sounds (easily noticed if you pay attention) and when that happens the latency was up too if you check the program. So there is a link to Winxp sp3 audio drivers

             

            I was trying different drivers here but couldnt get them to install, windows said the best drivers were already installed. http://catalog.update.microsoft.com/v7/site/Search.aspx?q=IDT%20high%20definition%20audio%20

             

            i have to use xp sp3 most of the time for professional reasons (since last week) so i would want this fixed instead of rebooting into win7 to hear a few songs.

             

            i know its a mature product and so don't expect to see half efficient drivers even when warranty period expires 3 years later!

             

            i didnt make any changes to the system, it is working well in all respects except this, which ive narrowed down to be a idt driver issue on xp.

             

            is it possible to somehow install win7 drivers in winxp sp3 since they are working fine?

              So are you saying the product has behaved this way for you all along? It'd certainly be worth attempting an audio driver uninstall/reinstall to see if that makes a difference. How did it perform with just a basic setup ie no audio diagnostic software installed and only the newly installed OS and drivers installed.

               

              How are the headphones connected to the PC (mine use the TOSLINK fibre optic port - are yours the same)? The same driver covers all supported versions of Windows (XP on).

                my headphones are using the regular 3.5 mm jack from the backpanel. well i installed winxp just a few days ago, its a fresh install of xp+drivers, when i do a fresh install of xp+drivers ,leaving out the audio drivers the latencies are normal, no spikes. i dont have any diagnostic software on it except the dpc latency program which i use to verify all drivers are working ok when doing a fresh install whether in xp or win7. before this i was single booting win7x64, with all drivers installed including audio there are no latency spikes, now i'm dual booting with winxp x86.

                 

                well as soon as i uninstall the drivers of IDT from device manager windows leaps and reinstalls it. doesn't give any chance to install a different set of drivers and when i try to update the driver it says the best drivers are already installed.

                  So it's always behaved this way - even with a simple (single boot) OS back in the beginning? You shouldn't need to install latency software to tell you whether the audio function is working properly - you can hear this. Were the skipping problems present on a single boot fresh install with no latency checking software installed? What player software is this using and what codecs were installed (to play what types of files)?

                    yes for windows xp. no for windows 7

                    i can hear it in windows xp x86. windows 7x64 is fine.

                    single boot was with windows 7 x64 previously. That worked flawlessly and is still working flawlessly in dual boot config. winxp is the problem. i've not tried single booting winxp.

                     

                     

                     

                    What player software is this using and what codecs were installed (to play what types of files)?

                    using anything wmp11 or vlc or youtube video or even OS sounds produce a slight crackle and spike the latency in windows xp. its interesting that when i play 2 audio sources then latency spikes go away i.e. playing vlc+youtube simultaneously =normal latency. but with only 1 playing, either vlc or youtube the latencies spike.

                     

                     

                     

                    edit update i played around with a fresh os install after formatting. the problem can be played around with the dolby control area of IDT control panel. the settings are dolby virtualisation of headphones and prologix II option in windows xp IDT control centre.

                     

                    Windows 7 IDT control centre doesnt have the dolby settings integrated maybe thts why it has no latency problem. Maybe the drivers are ok for even XP, it is just the way dolby is integrated which is causing the problems.

                     

                    now how do i fix this?! someway to install the drivers only without the idt control panel in windows xp?

                        I suspect your problems under XP might be associated with the fact you've only ever had XP in a dual boot scenario on this PC. My hunch is if you install only XP and its drivers, the sound problems will go away. As the same driver package installs for both OSs (possibly with files of a common name for both OS's sharing similar locations), I suspect some driver mix ups are occurring due to dual booting. The best way to have a dual boot PC (if you really must) is to have each OS installed on its own HDD and choose OS's by selecting in the BIOS, which drive to boot from by moving it up the boot priority list.

                         

                        I know of no way to install the drivers without the IDT control panel because even if your right click install from device manager on the driver archives contents, the IDT Control Panel still ends up being installed (although under Win 7, this won't give you a listing under programs you can uninstall - unlike an installation performed by running the drivers exe file). I'd sure be interested to know how it goes on a standalone installation of Win XP - as mentioned I briefly had XP (Media Centre 2005) on my DG45ID and I didn't notice any audio problems. In fairness it was only for a couple of days until I replaced it with Windows 7 but I think I still would have noticed any audio problems unless they were VERY minor.
