Use "WIN" + "I" > Update & Security to find the troubleshooters.
However, because Microsoft has some relocated the troubleshooter (depending on your version of Windows) just type "Troubleshoot" in the "Type here to search" box.
You should see "Troubleshoot" System Settings appear. Along with a small wrench icon.
You can likewise type in "Device Manager" to find and identify your audio card(s). There may be a built in card and/or a PCIe slotted card.
Avoid downloading drivers from other than the manufacturer's website. Sometimes an older driver will work. Avoid downloads from 3rd party sites. Such sites should be last resort only. Watch out for fake links and obvious download buttons that really download something else. Read carefully and check the URL that should appear when a link is moused over.
