  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 18           outdated but still useful information as well.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.

106         help
107           This is used to avoid config and link hard dependencies between the
108           sound subsystem and other function drivers completely unrelated to
109           sound although they're sharing the AC97 bus. Concerned drivers
110           should "select" this.
