Try the excellent soundpack from FTsim: https://x-plane-sounds.blogspot.com/2020/05/the-genx-queen.html

I haven't used these models in a while but from memory: Check that your bleeds (x2) are set to "Both" on the right-hand side of the overhead panel. I think they're set to off by default + hence your plane is unpressurised.
