|

| 83 | <acronym>ALSA</acronym> Driver</application> package to build the sequencer
|
---|
| 84 | modules. Most people want
|
---|
| 85 | them so you will usually want to leave it set to yes.</para>
|
---|
| 86 |
|
---|
| 87 | <para><parameter>--with-oss=yes</parameter>: This tells the package to
|
---|
| 88 | build the <acronym>OSS</acronym>/Free emulation modules. Again, most people

| 89 | want this so it's probably best to stick with yes.</para>

|
---|
| 93 | support isn't needed. If you are using an <acronym>ISA</acronym> PnP sound card,
|
---|
| 94 | it's best to say yes here. If your card is <acronym>ISA</acronym>, but

| 95 | not PnP, it is safer to stay with 'no'.</para>
|

| 96 |
|

| 99 | on which drivers are available, see <command>./configure
|
---|
| 100 | --help</command>. If you aren't sure which chipset your sound card uses,
|

---|
| 102 | <application><acronym>ALSA</acronym> Driver</application> source
