  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.
  37
  38          If unsure, say Y.

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