Based on my humble experience, I must say that at least in my case, the sound I get from a Sound Blaster X7 with pipewire, I never got it with windows and the driver of the card. I am using MX Linux 23.1. to which I have added the pipewire and wirepumbler repositories, which ensures that I have the latest software available, and at the time of writing this entry pipewire has been updated to version 1.0.

I don't use any effect, but the connection is direct to the DAC/AMP and from there to the speakers.
