libsdl-sound1.2 binary package in Ubuntu Precise amd64

 This library is meant to make the programmer's sound playback tasks
 simpler. The programmer gives SDL_sound a filename, or feeds it data
 directly from one of many sources, and then reads the decoded waveform
 data back at her leisure.
 .
 If resource constraints are a concern, SDL_sound can process sound
 data in programmer-specified blocks. Alternately, SDL_sound can
 decode a whole sound file and hand back a single pointer to the whole
 waveform. SDL_sound can also handle sample rate, audio format, and
 channel conversion on-the-fly and behind-the-scenes, if the programmer
 desires.
