NAME

       randomsound - ALSA sound card related entropy gathering daemon.

SYNOPSIS

       randomsound [options]

DESCRIPTION

       Using  the  low	order bit of the ADC output of your sound card, randomsound gathers entropy, debiases it and offers it up to your kernel's
       random pool. It can be tweaked to only write into the pool when it drops below a certain level, and to back  off  once  the  pool  is  full
       enough.	This build will set your sound card into 16 bit mono unsigned input at 8KHz.  If your sound card cannot do that then you will need
       to change the defines in asoundrunner.c and recompile the package. You must have set up asound as root on your machine. This  can  be  done
       with the asoundconf tool and its set-default-card command.

       You  may  also need to use the alsamixer to ensure that the sound card is generating plenty of noise. Set all the gains nice and high, turn
       on any boosters you have. If you have a V_REFLVL or similar then consider tweaking that.

OPTIONS

       -D     Daemonize

       -v     Increase verbosity. Can be used more than once.

       -m     specify minimum number of bits of entropy in the pool.

       -M     specify max number of bits in the pool.

       -b     specify number of bytes of randomness to buffer for use.

       -d     specify number of bytes to deposit into the pool each time.

       -h     display help message

       -V     display version information.

NAME

       sndconfig - configure sound card for use with Linux kernel modules

SYNOPSIS

       sndconfig {--help,--noprobe,--noautoconfig}

DESCRIPTION

       sndconfig sets up the necessary configuration files to use a sound card on a Red Hat system. If PnP support is compiled in, by default snd-
       config will do an initial probe for PnP sound cards using the pnpdump utility.  If the --noprobe option is given this step will be skipped.
       The  user  will	be notified if any cards were found. Otherwise the user must pick the card type from a menu. Then the user must choose the
       I/O port, IRQ, and DMA settings for the sound card. These must be known ahead of time and depend upon the  jumper  settings  of	the  sound
       card.   For PnP cards, the program will determine settings for the card; if the --noautoconfig option is given the user can choose the val-
       ues which will be programmed into the PnP device. There is no guarantee that the values entered do not conflict with an existing non-PnP or
       PnP device.  The user must make sure these types of conflicts do not occur.

   OPTIONS
       --help Print a usage message on standard output and exit successfully.

       --noprobe
	      No probe will be made for PnP cards, and the PnP configuration files will not be changed.

       --noautoconfig
	      No autoconfiguration of PnP cards will be done; the user will be prompted for settings.
