7    help
8      If you have a sound card in your computer, i.e. if it can say more
9      than an occasional beep, say Y. Be sure to have all the information
10      about your sound card and its configuration down (I/O port,
11      interrupt and DMA channel), because you will be asked for it.
12
13      You want to read the Sound-HOWTO, available from
14      <http://www.tldp.org/docs.html#howto>. General information about
15      the modular sound system is contained in the files
16      <file:Documentation/sound/oss/Introduction>. The file
17      <file:Documentation/sound/oss/README.OSS> contains some slightly
18      outdated but still useful information as well. Newer sound
19      driver documentation is found in <file:Documentation/sound/alsa/*>.
20
21      If you have a PnP sound card and you want to configure it at boot
22      time using the ISA PnP tools (read
23      <http://www.roestock.demon.co.uk/isapnptools/>), then you need to
24      compile the sound card support as a module and load that module
25      after the PnP configuration is finished. To do this, choose M here
26      and read <file:Documentation/sound/oss/README.modules>; the module
27      will be called soundcore.

38    default y
39    help
40      With this option enabled, the kernel will claim all OSS device
41      numbers if any OSS support (native or emulation) is enabled
42      whether the respective module is loaded or not and try to load the
43      appropriate module using sound-slot/service-* and char-major-*
44      module aliases when one of the device numbers is opened. With
45      this option disabled, kernel will only claim actually in-use
46      device numbers and opening a missing device will generate only the
47      standard char-major-* aliases.
48
49      The only visible difference is use of additional module aliases
50      and whether OSS sound devices appear multiple times in
51      /proc/devices. sound-slot/service-* module aliases are scheduled
52      to be removed (ie. PRECLAIM won't be available) and this option is
53      to make the transition easier. This option can be overridden
54      during boot using the kernel parameter soundcore.preclaim_oss.
55
56      Disabling this allows alternative OSS implementations.
57
58      Please read Documentation/feature-removal-schedule.txt for
59      details.

135      This is used to avoid config and link hard dependencies between the
136      sound subsystem and other function drivers completely unrelated to
137      sound although they're sharing the AC97 bus. Concerned drivers
138      should "select" this.
