Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

menuconfig SOUND
	tristate "Sound card support"
	depends on HAS_IOMEM || INDIRECT_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 SOUND

config SOUND_OSS_CORE
	bool
	default n

config SOUND_OSS_CORE_PRECLAIM
	bool "Preclaim OSS device numbers"
	depends on 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.

	  Say 'Y' or 'M' to enable ALSA (Advanced Linux Sound Architecture),
	  the new base sound system.
