I recently re-installed win98 SE and am having problems relocating the correct driver for my sound card. I ran a program called PCWizard to identify the specs of my sound card, and it listed it as

PCI Device audio : 82801BA/BAM (ICH2/ICH2-M) AC'97 Audio Controller

and

Audio Playback : AC'97 Sound Card

I went to DriverGuide.com and downloaded the following driver which corresponded to the sound card

AC'97 Driver for Intel(r) 82801 BA/BAM Controller

After installing and rebooting, my sound does work, but something is not right about it...all sounds (movies, music, general sounds) from every player I have are high pitched...similar to one's voice after inhaling helium.

I checked the device status and it says everything is working properly...I even tried downloading and installing 2 other identical drivers from the site, with the exact same results...

Anybody know what might be causing this and how I might go about fixing it?

Thanks in advace!

Chances are you are using the wrong drivers. Use the following information to identify the Vendor's ID as well as the Device ID. Although this information is directed to identify unknown devices and Standard VGA devices, it could also be use for this purpose. In your case the PCI device may appear in the registry as "Class=Audio Controller". Here is the information:

Microsoft Database:

SUMMARY

This article describes how to identify and locate vendor information for a device that is displayed as Unknown Device on the Device Manager tab in the System Properties dialog box.

This method can also be used to identify an unknown display adapter listed as Standard PCI Graphics Adapter (VGA).

MORE INFORMATION

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

When you install Microsoft Windows, the Add New Hardware Wizard may search for drivers for an unknown device. When Windows searches for the best driver for the device and it is unable to find one, you way receive the following message:
Unknown Device
Windows has not installed a driver for this device.

When you click View devices by type on the Device Manager tab in the System Properties dialog box, the device may be displayed as Unknown Device under Other devices.

When your computer starts, the Peripheral Component Interconnect (PCI) devices are polled for the following information:
Vendor ID
Device ID
Subsystem ID
Hardware Revision ID

This information is stored in the following Windows registry location:
HKEY_LOCAL_MACHINE\Enum\PCI\VEN_<vendorID>&DEV_<deviceID>&SUBSYS_<subsystemID>&REV_<hardwarerevisionID>

Where <vendorID> is a four-digit hexadecimal vendor ID number, <deviceID> is a four-digit hexadecimal device ID number, <subsystemID> is a subsystem ID number, and <hardwarerevisionID> is a hardware revision ID number.

To use this information to help you identify the unknown device, follow these steps:

Click Start, and then click Run.
Type Regedit in the Open box, and then click OK.
Expand the following registry subkey:
HKEY_LOCAL_MACHINE\Enum\PCI

Under PCI, expand one of the following subkeys.
VEN_vendorID&DEV_deviceID&SUBSYS_subsystemID&REV_hardwarerevisionID

For example:
VEN_11C1&DEV_0442&SUBSYS_04401668&REV_01

Click the folder that appears beneath the subkey that you expanded in step 4.

In the right pane, record the values of following registry entries that appear:
Class
DeviceDesc
Mfg

"Class" is the class of the device, such as "Modem". "DeviceDesc" is the description of the device, such as "Lucent Win Modem." "Mfg" is the device manufacturer, such as "Lucent."

To identify an unknown PCI device, follow these steps:

View the registry entries in the folder that appears in each of the registry subkeys under the following registry key:
HKEY_LOCAL_MACHINE\Enum\PCI

Note the Class registry entry with the Data value of "Unknown".

Record the following information of the parent registry subkey where this value is located:

Vendor ID
Device ID
Subsystem ID
Hardware Revision ID

For example, the Unknown Data value is found in the subfolder of the following registry subkey:
HKEY_LOCAL_MACHINE\Enum\PCI\VEN_11C1&DEV_0442&SUBSYS_04401668&REV_01

In that case, record the following information: Vendor ID 11C1
Device ID 0442
Subsystem ID 04401668
Hardware Revision ID 01

To identify a display adapter that is listed as Standard PCI Graphics Adapter (VGA), follow these steps:

View the registry entries in the folder that appears in each of the registry subkeys under the following registry key:
HKEY_LOCAL_MACHINE\Enum\PCI

Note the DeviceDesc registry entry with the Data value of "Standard PCI Graphics Adapter".

Record the following information of the parent registry subkey where this value is found:
Vendor ID
Device ID
Subsystem ID
Hardware Revision ID

For example, the "Standard PCI Graphics Adapter" Data value is found in the subfolder of the following registry subkey:
HKEY_LOCAL_MACHINE\Enum\PCI\VEN_8086&DEV_7121&SUBSYS_801F104&REV_03

In that case, record the following information: Vendor ID 8086
Device ID 7121
Subsystem ID 801F104
Hardware Revision ID 03

Start Microsoft Internet Explorer, and then visit the following PCI Vendor and Device Lists Web site:

http://www.pcidatabase.com/

Microsoft provides third-party contact information to help you find technical support. This contact information may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information.

Click the By Vendor ID link.
Click the 0xVendor ID link, where Vendor ID corresponds to the Vendor ID that you recorded in step c. For example, click 0x11C1 AT&T Microelectronics.

On the Vendor Information page, search for the 0xDevice ID, where Device ID corresponds to the Device ID that you recorded in step c. For example, 0x0442.

Record the Device ID information that corresponds to this Device ID. For example:

Chip Number: 1646T00
Description: V.90 Lucent Modem
Notes: Drivers http://808hi.com/56k/ltwin7.htm

Use this information to locate a compatible driver for the device.

Let us know how it goes!

thank you for the prompt response...

ok, I ran through these steps to verify that I had the correct driver, and apparently I do...

Vendor Id: 0x8086
Short Name: Intel

0x2442 Chip Number: 82801BA/BAM
Chip Description: USB Controller, USB-A
Notes: device #31, function #2, i820 chipset (Camino2)

When I did a search on this, I came across the same files as I downloaded earlier...

AC'97 Driver for Intel(r) 82801BA/BAM Controller

....containing the files.....

Ksproxy.ax
wdma_int

So, after another install and reboot, the sound is still off pitch...am I doing something wrong?

I would suggest you download the latest DirectX and perform a diagnostic:

http://www.microsoft.com/windows/directx/default.aspx?url=/windows/directx/downloads/default.htm

To run a diagnostic, go to Start->Run, type dxdiag and click Ok.

Also open the Volume Control Properties and adjust the settings to your preferences.

Another suggeston will be to test your speakers by conneting them to a device such as a CD player or walkman. If you are using a powered speaker sytem, the problem could be due to a malfuctioning amplifier.

Ok now I am extremely confused and frustrated...after running directx diag, it identified my sound card slightly different than before...

Realtek AC'97 Audio
Vendor 8086
0x2445

I went to the pci database and located this model, and it had a link to the Realtek website to download the driver...after the download, it automatically ran through an install wizard and installed the components...after restarting my computer, Windows would not load up and gave me a fatal exception error at 0028:C0014FDO (??? I have no idea what this means)...I then manually restarted my computer and Windows was able to load due to the automatic skip driver function...I looked at the device manager and it says that Realtek AC'97 Audio device is there, but has a problem...(Code 11??)...I went to driverguide.com and tried two different versions of drivers that matched this model, but when I try to update them it says that it is currently using the best one....and now there is NO sound coming from my speakers. I checked my speakers with my iPod, and they work fine...I'm lost now

Remove the item from the Device Manager. Restart the computer. Do whatever possible to redetect this device as an Unknown Device. Even if you have to remove the drivers being used reflected in the Device Manager from your Computer. Once you are unable to load the device and Windows recognizes the Device as an Unknown Device, Then use the entries in the Registry to find the Vendor ID and Device ID under an Unknown PCI Device.

Reinstall Multimedia. You will need the Windows 98 installation CD of your installation files must be dtored in your computer.

Go to the Control Panel->Add/Remove programs. Select Windows Components. Remove the check mark fom Multimedia. Click Apply, then OK.

Repeat the process, except that this time around put a check mark under Multimedia. Click Apply, then Ok, restart the omputer.

When you reinstalled Windows. What type of installation was performed? Clean Install? Parallel Install? -or- Installed over the existing installation?
