Would something like this also work with the old PCI X-Fi cards?
My sound card is X-Fi Xtreme Music PCI.
I also have the same problem that no sound comes out after updating 1809 to 1903 today. Of course it worked perfectly on 1809.
I tried following the Bryan86_HU's guide, but DON'T WORK. :( I tested with the official Audigy RX and the latest X-Fi Xtreme Music official driver, both failed.
Windows update even don't provide any driver available. Microsoft must fix this serious bug ASAP. It looks like I have to go back to 1809 for now.
