Conexant Audio Driver for Windows 7

Hi all

I am a user of HP Pavilion dv1000 laptop (PR428UA #ABA), which is a very primitive model, but after upgrade the RAM to 1 GB, I changed the OS from Win XP to Win 7, and it's useful for now. In my view, that it is faster than when it was on XP.

The problem is, I can't get the audio driver Conexant Cx20468 @ Intel 82801DBM ICH4-M - AC 97 Audio Controller [B-1], for Windows 7.

Yes, I already checked several messages in this forum and tried the similar drivers such as sp40270.exe or sp37816.exe.

But it does not work.

What I have to give up this challenge because he's too old for laptop?

Thank you.

Hi, Jun:

Sorry, that didn't work. I was hoping he would because it was an AC-97 audio driver.

I have another simple idea that you can try.

If you have your laptop connected to the internet, click the audio device in Device Manager. Click the driver tab click on Update driver. Select the automatic search method and I hope that Windows Update will download and install an audio driver for it.

I'm sure that your laptop should be able to run Windows 7, including audio.

If this does not work, try this method of complicated... change the driver XP for work in W7... but you should be able to do. Just follow the instructions carefully:

1. download the sp30399 driver.   You can get it here:

http://h10025.www1.HP.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-31530-1 & LC = on & CC = US & DLC = in & Product = 1816346 & os = 228 & lang = in

2. run sp30399.exe.

3 go to the extracted folder (default location is: c:\SWSetup\sp30399)

4. change qta3091.inf:
Search code block:
[Conexant]
% * WDM_AMCAUD. DeviceDesc%=WDM_AMCAUD,PCI\VEN_1002 & DEV_4370 & SUBSYS_3091103C

and add this line to the title:
% * WDM_AMCAUD. DeviceDesc%=WDM_AMCAUD,PCI\VEN_10B9 & DEV_5451 & SUBSYS_0024103C & REV_02

So the result would look like this:
[Conexant]
% * WDM_AMCAUD. DeviceDesc%=WDM_AMCAUD,PCI\VEN_1002 & DEV_4370 & SUBSYS_3091103C
% * WDM_AMCAUD. DeviceDesc%=WDM_AMCAUD,PCI\VEN_10B9 & DEV_5451 & SUBSYS_0024103C & REV_02

Note: Copy this part of the Device Manager > Multimedia Audio Controller > Details > hardware ID:
PCI\VEN_10B9 & DEV_5451 & SUBSYS_0024103C & REV_02

You can have a slightly different description of the device. If you want to be sure, go to Device Manager, open the properties of the audio device not recognized, select the "Détails" tab and select "Hardware ID" in the drop-down list properties drop-down list. Copy the listed top hardware ID string and replace the description of device I wrote above, with one you see.

So the final result is as follows (if you have a description of different device.):
[Conexant]
% * WDM_AMCAUD. DeviceDesc%=WDM_AMCAUD,PCI\VEN_1002 & DEV_4370 & SUBSYS_3091103C
% * WDM_AMCAUD. DeviceDesc%=WDM_AMCAUD,PCI\VEN_INSERT YOUR DESCRIPTION OF THE DEVICE ID

5. now, all you have to do is to install the driver manually through the Device Manager (Driver tab > update driver > select manual installation method and browse to the extracted driver folder (sp30399).)

Good luck and please let us know if you get the sound to work.

  • T400: Problem and FIX for UK Conexant Audio Driver for Windows Vista and XP (4.92.2.0 2009/04/23)

    Hello

    I installed the new drivers Conexant for my T400 (the driver is also for R400, R500, T400, T500, W500, W700, W700ds, X 200, X200s, X 200 Tablet, X 301) yesterday.

    This morning I had to adjust the smart-audio feature works correctly with my helmet of docking station for VoIP calls. The control panel SmartAudio applet would work well. It crashes.

    Today a .net developer and that it is a .net application I got it debugged in Visual Studio. The problem, apparently, is that the folder "C:\Program Files\CONEXANT\SAII\en-GB" does not exist on my machine. Of course, it is true. The solution is to go to "C:\Program Files\CONEXANT\SAII" and copy the contents of the "en-US" folder to a new folder "en-GB".

    Just thought I'd share this incase anyone else has problems and so Lenovo can fix if all goes well the installation. I suspect it will be wishful thinking, to provide them with real ENGLISH values for resources in en - GB instead of corrupt English which is probably in the American version resources

  • IDT audio driver for Windows XP

    Hello

    I have a DV7-1050ef downgraded to XP. I know that HP does not support Windows XP more.

    Anyone found yet an IDT audio driver for Windows XP? I have already tried many, none of them worked.

    I also installed the UAA kb888111.exe driver. Do I need to install anything else before the driver IDT?

  • T430u Audio driver for Windows 8.1

    Hello. When Lenovo will get out a compatible audio driver Windows 8.1 for T430u? I'm looking forward to upgrade to 8.1 Windows but found that no audio driver for T430u supports Windows 8.1 of the Lenovo Web site.

    Please update the audio driver for Windows 8.1, please take care.

    Hello

    Welcome to the Community Forums of Lenovo!

    Apologize for the inconvenience caused and thank you for the patience. Windows 8.1 is totally new approach and cannot be considered only as an update for Windows 8. Therefore, compatible drivers needs to be rethought so that they work properly in Windows 8.1. From now on, I can't engage the exact date of arrival of the missing drivers for T430u. You can expect it in the next few days, perhaps a week or even a month to release full and final of all drivers.

    Best regards

    Mithun.

  • Audio driver for windows 10

    Hello

    I have an Inspiron 14R 5420 that is updated to windows 10. Since Windows 8.1, I have a problem with an EXTREMELLY STRONG NOISE on my internal mic and I used "High definition Audio Device" driver by Microsoft.
    Three days ago, that I decided to install a driver from dell support list. In my case, is exactly this: www.dell.com/.../DriversDetails; Starts = 3499109433 & WB64A = osCode & productCode = inspiron-14r-5420 & languageCode = BP, EN & categoryId = to THE

    "Wow, incredible, my microphone is working correctly now, yay", I even called some people on Skype and it was fine. But yesterday the laptop stopped recognizing my headset (I is not yet in the list 'Device Manager') and the audio does not work.

    Well, I found a lot of other people with the same problem and the solution was to change the driver to "High definition Audio Device". I did sound returns, but my microphone is always noisy.

    Why the audio stopped suddenly? I tried to restore the system, but it has not solved the problem.

    Now I'm back with the microsoft driver and no microphone. The ideal was to have a driver that works correctly, but this is not the case. How can I handle the noise in my microphone without the conexant driver? Or will resolve this incompatibility between W10 and conexant problem?

    Hello. Have you tried to delete the driver Conexant completely from the laptop, then download and re-install?

    My guess is that Windows Update is changing the driver to something that does not work. This 'feature' cannot be defeated in most of the versions of Win10 so it may be best to simply go back to Win8.1 and install the Conexant audio driver in this system. The same version of the pilot work for 8.1 and 10.
