   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  15          outdated but still useful information as well.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.

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

  55          Please read Documentation/feature-removal-schedule.txt for
  56          details.

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