Let's consolidate all modules under one path, so that NixOS,
home-manager, and nix-darwin (if I ever end up using it down the line)
would go under the same folder.
This configuration file completely breaks my sound setup.
Will investigate more at a later time, in the mean time, since this is
basically the default options, I will just remove the configuration
file.
This reverts commit c987206bc5.
