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  18           outdated but still useful information as well.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

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

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