The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux operating system. 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 ([[SMP_Design|PLEASE READ THIS]]).
* 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.

Introduction
The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux operating system. 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 (PLEASE READ THIS).
  • 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.

Please, help us to provide better content and organisation on this wiki. Read the Community Portal for more details.
