+          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 unusre, say Y.
