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.
* 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.
This package provides utilities for configuring and using ALSA.
