iecset - Set or dump IEC958 status bits
iecset [options] [cmd arg...]
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
The commands consist of the command directive and the argument. As the boolean argument,
yes, no, true, false, or a digit number is allowed.
Displays the current IEC958 status bits on the second card. This is equivalent
with -c 1.
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

Sets the current status to the consumer-mode and turns on the non-audio bit. The
modified status will be shown, too.
Specifies the device name of the control to open
Specifies the card index to open. Equivalent with -Dhw:x.
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.
The professional mode (true) or consumer mode (false).
The audio mode (true) or non-audio mode (false).
The sample rate in Hz.
The emphasis: 0 = none, 1 = 50/15us, 2 = CCITT.
Rate lock: locked (true), unlocked (false). This command is for the professional
