\* Efficient support for all types of audio interfaces, from consumer sound
  cards to professional multichannel audio interfaces.
\* Fully modularized sound drivers.
\* SMP and thread-safe design.
\* User space library (alsa-lib) to simplify application programming and
  provide higher level functionality.
