menuconfig CONFIG_SOUND
	tristate "Sound card support"
	depends on CONFIG_HAS_IOMEM
	help
	  If you have a sound card in your computer, i.e. if it can say more
	  than an occasional beep, say Y.

if CONFIG_SOUND

config CONFIG_SOUND_OSS_CORE
	bool
	default n

config CONFIG_SOUND_OSS_CORE_PRECLAIM
	bool "Preclaim OSS device numbers"
	depends on CONFIG_SOUND_OSS_CORE
	default 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.

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