I was unable to find this model listed on any Sony website so.....
Open Device Manager, find the sound device and double-click it, click the Details tab, select "hardware id" and give me the hardware id string that appears under that screen that starts with "PCI\VEN", (1st./top line of text only). Open Notepad and manually type the string carefully, then recheck it for accuracy then copy and paste it into your next post.
