help
If you have a sound card in your computer, i.e. if it can say more
than an occasional beep, say Y. Be sure to have all the information
and read <file:Documentation/sound/oss/README.modules>; the module
will be called soundcore.
- I'm told that even without a sound card, you can make your computer
- say more than an occasional beep, by programming the PC speaker.
- Kernel patches and supporting utilities to do that are in the pcsp
- package, available at <ftp://ftp.infradead.org/pub/pcsp/>.

+ help
+ With this option enabled, the kernel will claim all OSS device
+ numbers if any OSS support (native or emulation) is enabled
+ whether the respective module is loaded or not and try to load the
+ appropriate module using sound-slot/service-* and char-major-*
+ module aliases when one of the device numbers is opened. With
+ this option disabled, kernel will only claim actually in-use
+ device numbers and opening a missing device will generate only the
+ standard char-major-* aliases.
+
+ The only visible difference is use of additional module aliases
+ and whether OSS sound devices appear multiple times in
+ /proc/devices. sound-slot/service-* module aliases are scheduled
+ to be removed (ie. PRECLAIM won't be available) and this option is
+ to make the transition easier. This option can be overridden
+ during boot using the kernel parameter soundcore.preclaim_oss.
+
+ Disabling this allows alternative OSS implementations.
+
+ Please read Documentation/feature-removal-schedule.txt for
+ details.
+
+ If unsure, say Y.

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