Alsa drivers for linux

How To Install alsa-base on Ubuntu 20.04

In this tutorial we learn how to install alsa-base on Ubuntu 20.04.

What is alsa-base

This package contains various configuration files for the ALSA drivers.

For ALSA to work on a system with a given sound card, there must be an ALSA driver for that card in the kernel. Linux 2.6 as shipped in linux-image packages contains ALSA drivers for all supported sound cards in the form of loadable modules. A custom alsa-modules package can be built from the sources in the alsa-source package using the m-a utility (included in the module-assistant package). Please read the README.Debian file for more information about loading and building modules.

ALSA is the Advanced Linux Sound Architecture.

Detailed package descriptions

alsa-driver

alsa-driver contains the ALSA components that run in kernel space (e.g. all the modules). It also contains a few user-space components, including the alsasound startup script and a set of ALSA headers.

This package is now obsolete. The kernel development continues in the standard linux kernel tree [2].
The old drivers (alsa-driver) are still available.

alsa-lib

alsa-lib contains the user space library that developers compile ALSA applications against.

alsa-utils

alsa-utils contains various generic ALSA command line tools, such as amixer, aplay, alsaconf, etc.

alsa-tools

alsa-tools contains various more obscure tools and loaders.

alsa-firmware

alsa-firmware contains binary drivers for various third-party products.

alsa-plugins

alsa-plugins contains plugins for various ALSA needs (e.g. Jack).

alsa-oss

alsa-oss contains the OSS compatibilty layer.

pyalsa

pyalsa contains the Python bindings for ALSA

.bz2 extension handling

The .bz2 extension belongs to the bzip2 compression utility which replaces gzip. You may unpack the .tar.bz2 files directly using one of the following commands:

using the newer version of tar: tar -xjf or, using the older version of tar: tar -xIf or, with all versions of tar: bunzip2 -c | tar -xf -

Advanced Linux Sound Architecture (ALSA) project homepage

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.
