 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.
