Bad sound quality Linux vs Windows

I think that what @Estilon is referring to is described in the following:
Audio Processing Object
Audio Signal Processing Modes
Linux offers what Win* calls “RAW processing” as a default; pipewire is powerful and flexible enough to implement any other mode described, but the “Pro Audio” and audio enthusiast audience has the like of JamesDSP while general purpose laptop users need model-specific tuning that manufacturers don’t see as economically viable to entice just a fraction of an already tiny share of linux desktop users.
And, BTW, Linux already has a huge market share in disguise, it is called “Android”, but runs on completely different HW with regard to sound physics…
