20 With this option enabled, the kernel will claim all OSS device
21 numbers if any OSS support (native or emulation) is enabled
22 whether the respective module is loaded or not and try to load the
23 appropriate module using sound-slot/service-* and char-major-*
24 module aliases when one of the device numbers is opened. With
25 this option disabled, kernel will only claim actually in-use
26 device numbers and opening a missing device will generate only the
27 standard char-major-* aliases.
28
29 The only visible difference is use of additional module aliases
30 and whether OSS sound devices appear multiple times in
31 /proc/devices. sound-slot/service-* module aliases are scheduled
32 to be removed (ie. PRECLAIM won't be available) and this option is
33 to make the transition easier. This option can be overridden
34 during boot using the kernel parameter soundcore.preclaim_oss.

36 Disabling this allows alternative OSS implementations.

5 If you have a sound card in your computer, i.e. if it can say more
6 than an occasional beep, say Y. Be sure to have all the information
7 about your sound card and its configuration down (I/O port,
8 interrupt and DMA channel), because you will be asked for it.

10 You want to read the Sound-HOWTO, available from
11 <http://www.tldp.org/docs.html#howto>. General information about
12 the modular sound system is contained in the files
13 <file:Documentation/sound/oss/Introduction>. The file
14 <file:Documentation/sound/oss/README.OSS> contains some slightly
15 outdated but still useful information as well. Newer sound
16 driver documentation is found in <file:Documentation/sound/alsa/*>.
17
18 If you have a PnP sound card and you want to configure it at boot
19 time using the ISA PnP tools (read
20 <http://www.roestock.demon.co.uk/isapnptools/>), then you need to
21 compile the sound card support as a module and load that module
22 after the PnP configuration is finished. To do this, choose M here
23 and read <file:Documentation/sound/oss/README.modules>; the module
24 will be called soundcore.
