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.

115 sound subsystem and other function drivers completely unrelated to
116 sound although they're sharing the AC97 bus. Concerned drivers
117 should "select" this.
