ALSA, also known as Advanced Linux Sound Architecture, is the default sound subsystem for most [[GNU/Linux]] distros, used most often in combination with [[pulseaudio]]. ALSA replaces OSS and a myraid of other convoluted solutions to Audio on Linux, and has remained somewhat stable for the last few years. Due to some drawbacks in the design and implementation of ALSA, pulseaudio is also used on many distros as a layer between software and ALSA to ensure that multiple applications can play sound simultaneously, something ALSA may stumble with natively.

The Advanced Linux Sound Architecture, shortened to ALSA, is the default sound system for most, if not all GNU/Linux distributions. ALSA replaced OSS after a new version of OSS was released under a non-free licence.

Usually on minimal GNU/Linux installations, the module dmix is sufficient to allow multiple programs to play sound at the same time. Most ready-made GNU/Linux distributions include PulseAudio and enable it by default to allow network transparency and per-application volume control, although many users exclude it because it is buggy and not worth the hassle. PulseAudio is now required to use Skype on GNU/Linux.
