If you have a sound card in your computer, i.e. if it can say more

than an occasional beep, say 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.

config AC97_BUS

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.
