4	help
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15	  outdated but still useful information as well.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.

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	  Please read Documentation/feature-removal-schedule.txt for
56	  details.

58	  If unsure, say Y.
