4 weeks ago, Creative Labs finally released a new driver package for their old X-Fi soundcard series finally.
(Myself having a Soundblaster X-FI Xtreme Gamer PCI sound card from 2007 myself) so finally the sound output for the analog output can be again selected in Windows 10 X64 1903 and the apps delivered with the driver work again, however some have been removed, so the package just only comes with the following tools:
-Creative Audio Control Panel
-Creative Software AutoUpdate
But better than nothing!
