ALSA has the following significant features: 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 (see these notes). User space library (alsa-lib) to simplify application programming and provide higher level functionality. Support for the older Open Sound System (OSS) API, providing binary compatibility for most OSS programs.
