ALSACTL(1) General Commands Manual ALSACTL(1) NAME
alsactl - advanced controls for ALSA soundcard driver SYNOPSIS
alsactl [options] [store|restore|init] <card # or id or device> DESCRIPTION
alsactl is used to control advanced settings for the ALSA soundcard drivers. It supports multiple soundcards. If your card has features that you can't seem to control from a mixer application, you have come to the right place. COMMANDS
store saves the current driver state for the selected soundcard to the configuration file. restore loads driver state for the selected soundcard from the configuration file. If restoring fails (eventually partly), the init action is called. init tries to initialize all devices to a default state. If device is not known, error code 99 is returned. If no soundcards are specified, setup for all cards will be saved or loaded. OPTIONS
-h, --help Help: show available flags and commands. -d, --debug Use debug mode: a bit more verbose. -v, --version Print alsactl version number. -f, --file Select the configuration file to use. The default is /etc/asound.state. -F, --force Used with restore command. Try to restore the matching control elements as much as possible. This option is set as default now. -g, --ignore Used with store and restore commands. Do not show 'No soundcards found' and do not set an error exit code when soundcards are not installed. -P, --pedantic Used with restore command. Don't restore mismatching control elements. This option was the old default behavior. -I, --no-init-fallback Don't initialize cards if restore fails. Since version 1.0.18, alsactl tries to initialize the card with the restore operation as default. But this can cause incompatibility with the older version. The caller may expect that the state won't be touched if no state file exists. This option takes the restore behavior back to the older version by suppressing the initialization. -r, --runstate Save restore and init state to this file. The file will contain only errors. Errors are appended with the soundcard id to the end of file. -R, --remove Remove runstate file at first. -E, --env #=# Set environment variable (useful for init action or you may override ALSA_CONFIG_PATH to read different or optimized configuration - may be useful for "boot" scripts). -i, --initfile #=# The configuration file for init. By default, PREFIX/share/alsa/init/00main is used. FILES
/etc/asound.state (or whatever file you specify with the -f flag) is used to store current settings for your soundcards. The settings include all the usual soundcard mixer settings. More importantly, alsactl is capable of controlling other card-specific features that mixer apps usually don't know about. The configuration file is generated automatically by running alsactl store. Editing the configuration file by hand may be necessary for some soundcard features (e.g. enabling/disabling automatic mic gain, digital output, joystick/game ports, some future MIDI routing options, etc).

envy24control(1) envy24control(1) 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. SEE ALSO
