longDescription = ''
apulse (${apulse.meta.homepage}) implements most of libpulse
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 libpulse.
pressureaudio (http://git.r-36.net/pressureaudio/) wraps apulse
with everything you need to replace libpulse completely.
This derivation is a reimplementation of pressureaudio in pure
nix.
You can simply override libpulse with this and most
packages would just work.
