6	  than an occasional beep, say Y.

17	default y
18	help
19	  With this option enabled, the kernel will claim all OSS device
20	  numbers if any OSS support (native or emulation) is enabled
21	  whether the respective module is loaded or not and try to load the
22	  appropriate module using sound-slot/service-* and char-major-*
23	  module aliases when one of the device numbers is opened.  With
24	  this option disabled, kernel will only claim actually in-use
25	  device numbers and opening a missing device will generate only the
26	  standard char-major-* aliases.
27
28	  The only visible difference is use of additional module aliases
29	  and whether OSS sound devices appear multiple times in
30	  /proc/devices.  sound-slot/service-* module aliases are scheduled
31	  to be removed (ie. PRECLAIM won't be available) and this option is
32	  to make the transition easier.  This option can be overridden
33	  during boot using the kernel parameter soundcore.preclaim_oss.
34
35	  Disabling this allows alternative OSS implementations.
36
37	  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.
