| 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>

|

| 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>

| 34 | components of <acronym>ALSA</acronym>: the libraries, the utilities, the

| 35 | tools, the firmware and the <acronym>OSS</acronym> compatibility
