You could give either of these two suggestions a try.....
1) D/load and install Everest Home Edition, available from here:
http://www.oldversion.com/program.php?n=everesthome
Scroll down to "Old Versions Available of Everest Home Edition" and select
Everest Home Edition 2.20.405
Once installed, launch Everest
In the opening window, click on the Computer icon in the right pane, then
click on the Summary icon
Scroll down to Multimedia, then look for Audio Adapter
2) Open the registry editor (Start>Run key in regedit then click on OK or
hit ENTER) and navigate to:
HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Enum>PCI
When you expand PCI, you should see quite a few registry keys, with names in
the general form such as this:
VEN_10B7&DEV_9004&SUBSYS_900410B7&REV_04
Each one corresponds to a PCI or AGP device on your system, and represents a
VENDOR ID string and a DEVICE ID string. In my example,the "Vendor ID" is
10B7 and the "Device ID" is 9004
If you expand each one in turn, they should each have a sub-key labelled
with a long hex number, for example:
3&61aaa01&0&58
Click on this sub-key, and look in the right pane for Class........for the
Unknown Device, the Class Data will be "Unknown"
Also look at DeviceDesc, it will probably say something like "PCI Multimedia
Audio Device"
Look thru each of these subkeys for the one that has the Class Data value of
"Unknown" and make a note of the Vendor ID and Device ID under which this was
found
Now, go here:
http://www.pcidatabase.com/vendors.php?sort=id
Look up the Vendor ID (you might have to scroll quite a ways to find it, or
do a "Find on/in this page" for the Vendor ID). For mine, I looked up 0x10B7,
which was related to 3COM Corporation. Now, click on the link for the Vendor.
Then look up the Device ID. Mine was 0x9004, which returned this information:
Chip Number: 3C900-COMBO
Description: Fast Etherlink XL PCI Combo NIC
Notes: Same as 9000 with TP and BNC connector with TP and BNC connecto
Following the above, you should be able to find out who made the device and
what it is, then that should give you a good idea of where to go to look for
drivers for it.
