Sigmatel AC97 audio driver 5.1 for the STAC 9750 on Windows Vista, XP and 2000


Description
The Sigmatel AC97 audio driver is for Windows Vista, Windows XP or Windows 2000 (used in lots of Dell, and other brand, pc models). Technically, it is the rather long winded:

Sigmatel C-Major STAC 9750 AC97 WDM Audio Driver.

Whatever way you to label it, the driver package installs version 5.1 of the driver onto your system and can be used as an update to an earlier driver or as part of a new installation.

What is the operating system installed on your laptop? Currently there's only windows xp sound drivers (click here). The sound card integrated with the laptop is SIGMATEL STAC 975X AC97.

If you need further help, let me know with more details.


Good luck.

Thanks for using FixYa.

The D610 has two audio jacks. The one closest to the monitor has a picture of a microphone above it, and the one closest to the user has a picture of headphones above it. Do you have your microphone plugged into the correct jack?

Please make sure that the sound driver is installed in your system, you can check this by right clicking on My Computer - Manage - Device Manager - Sound, Video and Game controller, and check whether there's any icon with the name Sigmatel Stac 97x Ac97, if it isn't there, it means there's no sound driver installed, or if there's a yellow mark (?) then driver wasn't properly installed or corrupt, or if you see an Unknown Device in that list, then driver had never installed, you need to reinstall it. To reinstall/install the sound driver, you have to Right click on the yellow icon, and Select Update Driver from the drop down list. You will be presented with a new dialog box "New Hardware Found Wizard" click "no not this time" and next, if you know the the directory of the driver, click browse and locate the directory with the particular folder where your driver is saved (maybe in a CD or in a folder directory) and click Ok - Next the wizard will search for the particular driver, again you will be presented with a warning dialog box "This driver is digitally not signed",click "Do you want to continue anyway" Yes - and the wizard will install the driver automatically. When it's done, it will show you that "the driver has been successfully installed" click Finish to close the wizard. On the other hand, if everything is normal and you can see the Sigmatel Stac 97x Ac97, then there must be problem with the sound card (hardware). You will need to replace it with a new Sound Card. I hope this will help you to troubleshoot this problem. In case you need to sound driver, you can download it from this link, http://dell.driversdown.com/dell-drivers-downloads/SIGMATEL-STAC-975X-AC97_1116.shtml If you can do it yourself, You can refer to this image presented below:

Hi

To ensure you have installed the drive properly

Please do the following to check

Start>Control Panel>System>(tab) Hardware> Click on device manager

Click on the + next to sound, audio and video properties

If there are yellow excalamtion marks in the Sigmatel then the driver has not been installed properly

Please redownload from the link below

If it is ok please do the following

Start>Control>sounds and audio devices and ensure the volume is nbot muted

Please leave feedback/vote if my answer was helpful

first of all check if you have sound in headphones if not go to start->accessories->system tools->system recovery and here chose day that you know that your sound was working. If it will not fix it try to reinstall sound drivers, and last hope is in reinstalling operating system. If you have sound in speakers its fault of your laptop speakers and you need to change them.

Go to this link, and download the XP audio driver. In a few minutes you should be up and running again.
