tristate "Sound card support"
If you have a sound card in your computer, i.e. if it can say more
than an occasional beep, say Y.
config SOUND_OSS_CORE_PRECLAIM
bool "Preclaim OSS device numbers"
depends on SOUND_OSS_CORE
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.
