18 | <para>The first question which people tend to ask about <acronym>ALSA</acronym>
|
---|
19 | is why they should use it over the sound drivers included in the
|
---|
20 | kernel—there are several reasons. First, the <acronym>ALSA</acronym>
|
---|
21 | drivers support more sound cards than those in the kernel. Second, the
|
---|
22 | <acronym>OSS</acronym> emulation is in some cases faster and better than the
|
---|
23 | original <acronym>OSS</acronym> driver itself. And finally, there are some
|
---|
24 | programs which can use <acronym>ALSA</acronym>'s enhanced features to better
|
---|
25 | drive the sound card.</para>
|

26 |
|
---|
27 | <para><acronym>ALSA</acronym> is also the future of Linux Sound (hence the
|
---|
28 | name <emphasis>Advanced Linux Sound Architecture</emphasis>). The
|
---|
29 | <acronym>ALSA</acronym> drivers were included into the main Linux kernel
|
---|
30 | during the 2.5 development series, and they are now the "standard" sound
|
---|
31 | drivers in the 2.6 stable kernel.</para>

33 | <para>The following five sections of the book deal with the five separate
|
---|
34 | components of <acronym>ALSA</acronym>: the libraries, the utilities, the
|
---|
35 | tools, the firmware and the <acronym>OSS</acronym> compatibility
|

36 | libraries.</para>
