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 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.
