0020 With this option enabled, the kernel will claim all OSS device
0021 numbers if any OSS support (native or emulation) is enabled
0022 whether the respective module is loaded or not and try to load the
0023 appropriate module using sound-slot/service-* and char-major-*
0024 module aliases when one of the device numbers is opened. With
0025 this option disabled, kernel will only claim actually in-use
0026 device numbers and opening a missing device will generate only the
0027 standard char-major-* aliases.
0028
0029 The only visible difference is use of additional module aliases
0030 and whether OSS sound devices appear multiple times in
0031 /proc/devices. sound-slot/service-* module aliases are scheduled
0032 to be removed (ie. PRECLAIM won't be available) and this option is
0033 to make the transition easier. This option can be overridden
0034 during boot using the kernel parameter soundcore.preclaim_oss.
0035
0036 Disabling this allows alternative OSS implementations.
0037
0038 If unsure, say Y.

0114 This is used to avoid config and link hard dependencies between the
0115 sound subsystem and other function drivers completely unrelated to
0116 sound although they're sharing the AC97 bus. Concerned drivers
0117 should "select" this.
