You can try to match the vendor and device ID to the database here:
PCI Vendor and Device Lists
In device manager check the information tab for the device, open the hardware-id property and read it from there.
It'll look something like this:
HDAUDIO\FUNC_01&VEN_1002&DEV_AA01&SUBSYS_00AA0100&REV_1000
VEN_xxxx = vendor ID
DEV_xxxx = device ID
Hope this helps.
