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 com-
       mands 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 argu-
	      ments 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.

COMMANDS
       professional <bool>
	      The professional mode (true) or consumer mode (false).

       audio <bool>
	      The audio	mode (true) or non-audio mode (false).

       rate <int>
	      The sample rate in Hz.

       emphasis	<int>
	      The emphasis: 0 =	none, 1	= 50/15us, 2 = CCITT.

       lock <bool>
	      Rate lock: locked	(true),	unlocked (false).  This	command	is for
	      the professional mode only.

       sbits <int>
	      Sample bits:  2 =	20bit, 4 = 24bit, 6 = undefined.  This command
	      is for the professional mode only.

       wordlength <int>
	      Wordlength: 0 = No, 2 = 22-18 bit, 4 = 23-19 bit,	5 = 24-20 bit,
	      6	= 20-16	bit.  This command is for the professional mode	only.

       category	<int>
	      Category:	 the value is from 0 to	0x7f.  This command is for the
	      consumer mode only.

       copyright <bool>
	      Copyright: copyrighted (true),  non-copyrighted  (false).	  This
	      command is for the consumer mode only.
