5      If you have a sound card in your computer, i.e. if it can say more
6      than an occasional beep, say Y. Be sure to have all the information
7      about your sound card and its configuration down (I/O port,
8      interrupt and DMA channel), because you will be asked for it.
9
10      You want to read the Sound-HOWTO, available from
11      <http://www.tldp.org/docs.html#howto>. General information about
12      the modular sound system is contained in the files
13      <file:Documentation/sound/oss/Introduction>. The file
14      <file:Documentation/sound/oss/README.OSS> contains some slightly
15      outdated but still useful information as well. Newer sound
16      driver documentation is found in <file:Documentation/sound/alsa/*>.
17
18      If you have a PnP sound card and you want to configure it at boot
19      time using the ISA PnP tools (read
20      <http://www.roestock.demon.co.uk/isapnptools/>), then you need to
21      compile the sound card support as a module and load that module
22      after the PnP configuration is finished. To do this, choose M here
23      and read <file:Documentation/sound/oss/README.modules>; the module
24      will be called soundcore.

32config SOUND_OSS_CORE_PRECLAIM
33    bool "Preclaim OSS device numbers"
34    depends on SOUND_OSS_CORE
35    default y
36    help
37      With this option enabled, the kernel will claim all OSS device
38      numbers if any OSS support (native or emulation) is enabled
39      whether the respective module is loaded or not and try to load the
40      appropriate module using sound-slot/service-* and char-major-*
41      module aliases when one of the device numbers is opened. With
42      this option disabled, kernel will only claim actually in-use
43      device numbers and opening a missing device will generate only the
44      standard char-major-* aliases.
45
46      The only visible difference is use of additional module aliases
47      and whether OSS sound devices appear multiple times in
48      /proc/devices. sound-slot/service-* module aliases are scheduled
49      to be removed (ie. PRECLAIM won't be available) and this option is
50      to make the transition easier. This option can be overridden
51      during boot using the kernel parameter soundcore.preclaim_oss.
52
53      Disabling this allows alternative OSS implementations.
54
55      If unsure, say Y.

131      This is used to avoid config and link hard dependencies between the
132      sound subsystem and other function drivers completely unrelated to
133      sound although they're sharing the AC97 bus. Concerned drivers
134      should "select" this.
