NAME


iecset - Set or dump IEC958 status bits

SYNOPSIS


iecset [options] [cmd arg...]

DESCRIPTION


iecset is a small utility to set or dump the IEC958 (or so-called "S/PDIF") status bits of
the specified sound card via ALSA control API.

When iecset is started without arguments except for options, it will show the current
IEC958 status in a human-readable form. When the commands are given in the arguments,
they are parsed and the IEC958 status bits are updated. The resultant status is shown as
well.

The commands consist of the command directive and the argument. As the boolean argument,
yes, no, true, false, or a digit number is allowed.

EXAMPLES


iecset -Dhw:1
Displays the current IEC958 status bits on the second card. This is equivalent
with -c 1.

iecset -x
Displays the current IEC958 status bits in a style of the arguments for the PCM
stream. The output string can be passed to the iec958 (or spdif) PCM type as the
optional argument.

iecset pro off audio off
Sets the current status to the consumer-mode and turns on the non-audio bit. The
modified status will be shown, too.

OPTIONS


-D device
Specifies the device name of the control to open

-c card
Specifies the card index to open. Equivalent with -Dhw:x.

-n index
Specifies the IEC958 control element index, in case you have multiple IEC958
devices and need to choose one of them.

-x Dumps the status in the form of AESx bytes.

-i Reads the command sequences from stdin. Each line has single command.
