   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  18          outdated but still useful information as well.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.

  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.

  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.
