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.
