+      apulse (${apulse.meta.homepage}) implements most of libpulseaudio
+      API over pure ALSA in 5% LOC of the original PulseAudio.
+
+      But apulse is made to be used as a wrapper that substitutes its
+      replacement libs into LD_LIBRARY_PATH. The problem with that is
+      that you still have to link against the original libpulseaudio.
+
+      pressureaudio (http://git.r-36.net/pressureaudio/) wraps apulse
+      with everything you need to replace libpulseaudio completely.
+
+      This derivation is a reimplementation of pressureaudio in pure
+      nix.
+
+      You can simply override libpulseaudio with this and most
+      packages would just work.
