Jim updated to Windows 10 vs. 1903 and now he's lost sound support and can't record. Can he downgrade? Leo says he could, but not for long. Microsoft is going to force it on him sooner or later. There is a known issue with sound in gaming. Leo recommends updating to the subsequent updates after 1903.
