Note that I'll have more review comments, but I wasn't able to build fftw with the following error:

│B│ if (/bin/sh '/mason/build/x86_64/fftw-3.3.10.tar.gz/.fftw/missing' makeinfo --version) >/dev/null 2>&1; then \

I notice that lsp-plugins is also missing from this. Other than those 3 things this looks good.

Added a patch to easyeffects that when the pipewire 1.4.0 pr lands it won't have any problems
