Help text

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.
