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

       envy24control - GUI control tool for Envy24 (ice1712) based soundcards, under ALSA.

SYNOPSIS

       envy24control  [-c  card-number]  [-D control-name] [-o 0-num DACs max 8] [-i 0-num ADCs max 8] [-p 0-8] [-s 0-2] [-f <profiles file name>]
       [-v] [<profile number>|<profile name>] [-m midi-channel] [-M] [-w window-width] [-t 0-9]

DESCRIPTION

       envy24control allows control of the digital mixer, channel gains and other hardware settings for sound cards based on the  ice1712  chipset
       (Midiman Delta series, Terratec EWS and EWX series). It also displays a level meter for each input and output channel.

INVOKING

       envy24control  [-c  card-number]  [-D control-name] [-o 0-num DACs max 8] [-i 0-num ADCs max 8] [-p 0-8] [-s 0-2] [-f <profiles file name>]
       [-v] [<profile number>|<profile name>] [-m midi-channel] [-M] [-w window-width] [-t 0-9]

       If no control-name is given, then the first sound card is used.

   Options
       -c card-number
	      Use the card specified by card-number rather than the first card.  This is equivalent with -Dhw:n option where n is the card number.

       -D control-name
	      Use the card specified by control-name rather than the first card, normally this will be of the form hw:n where n is the sound  card
	      number (zero-based). This is only needed if you have more than one Envy24-based card or if your Envy24 card is not configured as the
	      first card in your ALSA driver setup.

       -o outputs
	      Limit number of analog line outputs to display.  Default is the number of DACs in the driver specification. Maximum is 8.  The  num-
	      ber of analog output lines can only be reduced from the available number of output lines.

       -i inputs
	      Limit number of analog line inputs to display.  Default is the number of ADCs in the driver specification. Maximum is 8.	The number
	      of analog input lines can only be reduced from the available number of input lines.

       -p pcm outputs
	      Limit number of PCM outputs to display.  Default is 8.

       -s spdif inputs/outputs
	      Limit number of SPDIF inputs/outputs to display.	Default is 2.

       -f name and path of the profiles file name.
	      From/to this file will envy24control read/write the alsactl  settings.   If  is  not  given  DEFAULT_PROFILERC  or  for  restore	if
	      DEFAULT_PROFILERC doesn't exists SYS_PROFILERC will be used.

       -v view spdif playback channels in the mixer.
	      It  is  not  possible to manage something (muting, volume levels).  It is only to view the levelmeters.  Default is no view of spdif
	      playback channels in the mixer.

       -m midi-channel
	      Use MIDI controller values to control the Faders in the mixer view.  The application will react to controllers on channel midi-chan-
	      nel and send controllers on this channel when the user moves the GUI sliders.

       -M     Use an enhanced mapping from midi controller values to db sliders.

       -w window-width
	      Specify  the initial width of the envy24control window.  Using window-width in the range 0-20 specifies approx number of mixer chan-
	      nels visible.  Values >20 are interpreted as screen pixels.

       -t tall-equal mixer heights
	      Using -t 1 enlarges the channel mixers to the same height as the digital mixer.	With  values  >1  the  height  of  all	mixers	is
	      increased in stages.  -t 0 is the default, set for minimum window height.
