easyeffects: fix bug 'missing spectrum analyzer'

Due to old version of lsp-plugins in nixpkgs, the delay plugin is
incorrectly inserting silence in the plugin output instead of the
processed audio. This has been fixed in lsp-plugins 1.2.17 but is not
in nixpkgs yet.

(cherry picked from commit c2df671cfc)
