<P>
|
|
The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI
|
|
functionality to the Linux operating system.
|
|
|
|
<P>
|
|
Logically ALSA consists of these components:
|
|
|
|
<UL>
|
|
<LI>A set of kernel drivers.
|
|
<BR>
|
|
These drivers are responsible for handling the physical sound
|
|
hardware from within the Linux kernel, and have been the standard
|
|
sound implementation in Linux since kernel version 2.5
|
|
</LI>
|
|
<LI>A kernel level API for manipulating the ALSA devices.
|
|
</LI>
|
|
<LI>A user-space C library for simplified access to the sound hardware
|
|
from userspace applications. This library is called <i>libasound</i>
|
|
and is required by all ALSA capable applications.
|
|
</LI>
|
|
</UL>
|
|
|
|
<P>
|
|
More information about ALSA may be found on the project homepage
