- than an occasional beep, say Y.

- 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.
- If unsure, say Y.
