Windows 10 version 1903 intentionally stopped my Sound Blaster Audigy FX sound card from functioning

Hi,

You might try to completely uninstall the drivers and software for the Audigy.

The reinstall as follows.

right click install executable and select "troubleshoot compatibility"

let troubleshooter do it's thing and hopefully it will end with a suggestion to try installing with "these settings', if it does give it a go. If it doesn't, try creatives website for updated drivers.

MOST of the driver issues are on the hardware manufacture not Microsoft. They way I understand it Microsoft will work with any hardware manufacturer to get their drivers updated to work with new Windows 10 releases. If Creative has chosen to NOT do that it is NOT Microsoft's fault and your only options at that point is to either downgrade to a Windows 10 version which has driver support for your hardware or upgrade your hardware.

I personally ditched Creative back in the late 90's/early 2000's just for their apparent lack of driver support for older hardware models. Superb hardware with lacking driver support does not make a good hardware purchase IMHO. For example a quick search of the Creative website revealed the latest driver release for your sound card was 2015.
