19	help
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.
