libcanberra-doc 0.30-10ubuntu2 (amd64 binary) in ubuntu lunar

 libcanberra defines a simple abstract interface for playing event
 sounds.
 .
 libcanberra relies on the XDG sound naming specification for
 identifying event sounds. On Unix/Linux the right sound to play
 is found via the mechanisms defined in the XDG sound theming
 specification.
 .
 This package contains the HTML documentation for libcanberra and
