    Serial Port In Intel DG965RY Motherboard


    Hi,

    I have a problem with the serial port on my Intel DG965RY motherboard, and would appreciate any help on resolving the issue:

    1. The TPS of the motherboard (available on Intel's download site - forum rules prohibit me from entering the URL address here) shows that the board has provision for a 9-pin serial port (page 28). However, when I opened the CPU box, I was unable to locate the serial port header as indicated by the accompanying diagram. Is it possible to have the actual motherboard provisions to be different from the TPS? Or am I looking in the wrong place?

    2. I have a device which can be connected to the CPU using a cable, whose CPU-end is a 9-pin female plug. Is there some way by which I can connect this plug to some place in the motherboard and make use of this device? (The device is a mobile phone, and using the cable I can access the internet.)

    Any suggestions on how I can resolve these issues?

    Thanks in advance.

    Components should be placed in about the same locations as mentioned on the tech specs. Some boards may have multiple versions/models within a series, but tech specs typically mention which model would be missing which component in the footnotes.

    Based on Intel's documentation, it should be green, placed between the ram slots, and look similar to JP2 as shown below.



    2. I have a device which can be connected to the CPU using a cable, whose CPU-end is a 9-pin female plug. Is there some way by which I can connect this plug to some place in the motherboard and make use of this device? (The device is a mobile phone, and using the cable I can access the internet.)
    If you can locate the header on the board, use a Serial Port Bracket . Most boards should include this bracket in the box.

    You can also get a USB-to-Serial adapter (plug into your USB slot, get a COM port). These can be handy, but some serial devices will flat out not work with them.

    There are always expansion cards you can put into PCI slots that will give you 2+ serial ports; this is probably the most expensive, and least recommended, of the three solutions.

    Serial Port Problem - Thanks!


    Hello "beleagured",

    Thank you very much!

    Because of the diagram, I could pinpoint more precisely the serial port header. I have managed to locate a Serial port bracket, and right at this moment, I am typing out this message using the mobile connected to the serial port of my own computer!

    The only uncertain element was the direction in which the female plug of the serial port cable had to be fitted into the male serial header. The header does not have any 10th pin, while the female plug had all 10 holes, so I hope there is no problem if the plug is inserted into the header any which way. (There _is_ a notch on one side of the plug, though, perhaps that should give some clue?)

    Thank you again for your help, much appreciated!

    Regards.

    Another problem - this time related to Sound


    Hi again,

    The success of this problem encourages me to ask for a solution to yet another problem; this time related to Sound.

    On this same motherboard (DG965RY), I am not able to hear any sound. My OS is XPSP3, and the TPS says the codec is SigmaTel STAC9227 audio codec.

    When it was working, the sound driver was indeed SigmaTel. Because the sound stopped coming, I installed the latest version of the sound device driver available on the download page for this motherboard on Intel's download site. So now I have IDT (IDT1 and IDT2). Yet no sound is coming.

    The download site has three different versions of sound codecs for this motherboard. When I install the SigmaTel version, there is absolutely no sound. But when I install the IDT version, I get very weak sound, almost muffled. All volume levels in the software panel are turned up.

    Any suggestions on how this problem can be resolved, will be much appreciated.

    Thanks in advance.

    The 10th "pin" on the header is labeled as a No Connect on the diagram, so the missing pin is to be expected. The connector (female plug) will have all 10 because those connectors typically come in even measurements. (n number of rows, both rows having identical lengths)

    The driver itself can be seen in Windows as "SigmaTel", but Intel took SigmaTel's chip/setup, wrote a driver specific to [i]the Intel/i] board and chipset, and then used the audio codecs themselves from SigmaTel.

    Intel's site has three listed. I would recommend trying #2 and #3. #8 on the list is an older driver set. As basic as it sounds, double check all of the settings in that Intel Audio tool you're using to make sure nothing is turned down/muffled. Then, go to the Control Panel and do the same within the Windows Sound settings itself. Lastly, make sure you're connected to the correct port on your sound card. :-)

    Assuming you're using drivers from here, which set (5790_5713_v83 or 5790.3v22) works with the muffled audio as you described?

    Also, just to play it safe, download the Chipset INF Utility (labeled as #2 on the list) and install the updated driver set for your chipset.

    Trying Alternative Sound Codecs


    Hello,

    Thank you for your guidance; much appreciated.

    As suggested by you, I uninstalled the driver of item #8 in the Intel's driver list, and installed 5790_5713_v83. This produces the muffled sound. Later this was uninstalled and the 5790.3v22 was installed. This too produces a muffled sound. The only difference I observed between the two is that the former comes with its own IDT control panel, while the latter comes with SonicFocus, Intel's own Audio Studio.

    In SonicFocus, clicking on "Test all speakers" produces a muffled sound, when the slidebars for all the four parameters - Dynamics, Brilliance, Solo Clarity and Deep Bass - are set to full.

    In DxDiag, clicking on "Test Direct Sound" for IDT1 and IDT2 too produces a very weak sound, as if a heavy handkerchief has been pressed on the speakers.

    I am reproducing here the output of DxDiag for sound:

    Microsoft seems to have gotten sloppy with KB888111's intended fixes properly working in SP3.

    Hold on to both of the driver sets that we know produce at least a muffled sound.

    Make sure you have the current chipset drivers from Intel. As mentioned before, you can get these from the download labeled "Chipset INF Utility" on Intel's list of downloads for your motherboard.

    Next, download KB888111 and completely uninstall whichever audio driver is installed.

    Restart your PC, and make sure you cancel and ignore any requests to install new hardware when Windows notices your sound driver is missing.

    Next, open the Registry Editor by going to Start-->Run-->regedit

    Navigate to the following key:
    HKEY_LOCAL_MACHINE/SYSTEM/CONTROLSET/CONTROL/WINDOWS/

    Within this path, there should be a registry entry labeled CSDVersion. If you edit it, the value should currently read 300. Change this to 200.

    After this has been changed, exit the registry editor, restart your system, install KB888111, and then install the either of the audio drivers we know produce muffled audio. Restart one more time and test the audio.

    If it sounds good, go back to the previous registry key and change it back 300.

    Installing KB888111


    Hello "beleagured",

    Thank you very much for your guidance; much, much appreciated.

    Before proceeding to install KB888111, just wanted to confirm that I already have XPSP3 installed on my system. Microsoft's documentation states that KB888111 issues have already been incorporated in SP3. And when I tried installing KB888111 using the copy that comes with these sound codecs, I get a message saying that my Service Pack is later than SP2 and therefore I need not install KB888111.

    I am proceeding with the steps given by you now, and your clarification on this point should put any confusion at rest.

    Thanks once again.

    The registry edit I have above basically forces Windows to think it's running in Service Pack 2, so it should allow you to pass the OS check when reinstalling KB888111.

    Three Versions Of ControlSet


    Hello "beleagured",

    Thank you for the clarification.

    In the regedit of my machine, after reaching

    HKEY_LOCAL_MACHINE/SYSTEM/

    I observe three versions of CONTROLSET:

    ControlSet001
    ControlSet002
    CurrentControlSet

    Each of these folders has four subfolders:

    - Control
    - Enum
    - Hardware Profiles
    - Services

    The /CONTROL/WINDOWS portion in each of these three has an entry CSDVersion. And the value in this entry is presently set to '300'.

    Which particular entry should be set to '200'? All the three? Or the 'CurrentControlSet'?

    Thanks in advance.

    Sorry,

    CurrentControlSet/Control/Windows

    The value for CSDVersion should be 300 currently. This is your system's way of knowing Service Pack 3 is installed. By changing it to 200 and restarting, the system will think it has Service Pack 2 for a while.

    Installing KB888111...


    Hello "beleagured",

    Thank you for your patience and guidance; much appreciated.

    Doing exactly as guided by you, the muffled voice has not yet improved. I used the 5790.3x_5713 version of the codec.

    Here is the latest relevant portion of DxDiag, if that could give any clues of what has changed between the earlier installation and this installation.

    The regedit value of CSDVersion continues to be 200. Should I revert to 300?

    Thanks again in advance.

    Yeah, you can change the registry key back to 300. SP3 doesn't have the best track record with High Def audo.

    The only other things I can think to do would be to specifically try another set of speakers or headphones on your system. As mundane as it may sound, leave some music or whatnot playing, and switch through the jacks on your sound card to see if anything actually pops up. Other than that, see if reverting to SP2 helps (if you can).

    After that, I'm out of ideas.

    Muffled sound from the headphone speakers


    Hello "beleagured",

    Thank you very much for all your help; much appreciated.

    Before launching the KB888111-installation experiment, I had set a restore point. I will revert back to this restore point to bring back the status quo.

    I had connected a set of desktop speakers to the machine, but they didn't give even the muffled sound that one could hear in the headphone. The same headphone works beautifully on another machine.

    The quirky thing is: I had installed SP3 about four months ago, and the then SigmaTel codec used to work quite well - till three weeks back. I remember there was a Windows upgrade that was downloaded and installed on the day the problem cropped up. So it is not SP3 per se that is the cause of the problem. It is the latest upgrade from Microsoft that is the problem. I wonder if there are other XPSP3 SigmaTel users out there that are in a similar predicament?

    Talking about restore points, when I click on any of the restore points that the Restore Calender shows for the past one month or so, the system says "Cannot revert back". Is this a Windows bug? To not revert to some earlier point? Or is this solvable at our level?

    Thank you "beleagured", for sparing your valuable time and putting in effort to help solve my earlier problem of serial port, and also for the sound card. My appreciation is sincere.

    Best.

    "Cannot Revert Back" on system restores is typically caused by either a corrupted restore point or some sort of AV software stopping you from restoring. Kapersky and Norton tend to be the big culprits. If you run either, try disabling the AV/Security suite and seeing if you can restore or try reverting to the restore point from Windows Safe Mode.
