Question about Creative Sound Blaster Audigy Fx

I bought a Sound Blaster Audigy Fx (PCI-Ex1) for my (then) new computer in Dec. 2018 and it is still running successfully today, now with Windows 11. However, I only use the Sound Blaster as an input and output port, I don't (know and) use any other functions.

However, I have found that not all audio software works fully with the Soundblaster, but this does not depend on the operating system.
