libasound2-plugins 1.0.17-0ubuntu4 (amd64 binary) in ubuntu jaunty

 This package contains plugins for the ALSA library that are
 not included in the main libasound2 package.
 .
 The ALSA library plugin "jack" allows the ALSA library to
 play or capture via JACK. (This should not be confused with
 the jackd output driver "alsa", included in the jackd
 package, which allows the JACK daemon to play back via the
 ALSA library.)
 .
 The PulseAudio library plugin "pulse" allows the ALSA
 library to play or capture via PulseAudio.
 .
 The OSS library plugin "oss" allows the ALSA library to
 play or capture via OSS.
 .
 Also included are enhanced resampling, a52 conversion, and
 Maemo ALSA library plugins.
 .
 Note that in the Ubuntu package the JACK, a52, and Maemo
 plugins are disabled by default due to build component
 separation and cd image capacity issues.
 .
 ALSA is the Advanced Linux Sound Architecture.
 JACK is the Jack Audio Connection Kit.
 OSS is the Open Sound System.
