  20           With this option enabled, the kernel will claim all OSS device
  21           numbers if any OSS support (native or emulation) is enabled
  22           whether the respective module is loaded or not and try to load the
  23           appropriate module using sound-slot/service-* and char-major-*
  24           module aliases when one of the device numbers is opened.  With
  25           this option disabled, kernel will only claim actually in-use
  26           device numbers and opening a missing device will generate only the
  27           standard char-major-* aliases.
  28
  29           The only visible difference is use of additional module aliases
  30           and whether OSS sound devices appear multiple times in
  31           /proc/devices.  sound-slot/service-* module aliases are scheduled
  32           to be removed (ie. PRECLAIM won't be available) and this option is
  33           to make the transition easier.  This option can be overridden
  34           during boot using the kernel parameter soundcore.preclaim_oss.
  35
  36           Disabling this allows alternative OSS implementations.

  38           If unsure, say Y.

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