menuconfig SOUND
tristate "Sound card support"
depends on 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. Be sure to have all the information
about your sound card and its configuration down (I/O port,
interrupt and DMA channel), because you will be asked for it.
You want to read the Sound-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. General information about
the modular sound system is contained in the files
<file:Documentation/sound/oss/Introduction>. The file
<file:Documentation/sound/oss/README.OSS> contains some slightly
outdated but still useful information as well. Newer sound
driver documentation is found in <file:Documentation/sound/alsa/*>.
If you have a PnP sound card and you want to configure it at boot
time using the ISA PnP tools (read
<http://www.roestock.demon.co.uk/isapnptools/>), then you need to
compile the sound card support as a module and load that module
after the PnP configuration is finished. To do this, choose M here
and read <file:Documentation/sound/oss/README.modules>; the module
will be called soundcore.

and want to use its audio codec chip.

depends on SOUND_OSS_CORE

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.
Please read Documentation/feature-removal-schedule.txt for
details.
If unsure, say Y.

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.
