SYNOPSIS

       codecgraph [-f format] [-h] [-o name] [-v] [codecfile]

DESCRIPTION

       codecgraph generates a graph based on the ALSA description of a High Definition Audio codec. The generated graph depicts the HDA codec lay-
       out  and  node  connections,  helping  driver  troubleshooting	and   maintenance.   In   Linux   this	 description   is   available	at
       /proc/asound/card*/codec#*.

OPTIONS

       -f format
	      Specify  the format of the generated graph. Valid formats are all formats accepted by dot(1), including ps (PostScript), svg (Struc-
	      tured Vector Graphics), fig (XFIG graphics) and png (Portable Network Graphics).

       -h     Show usage information and exit.

       -o name
	      Set the output file name.

       -v     Print version information and exit.

EXAMPLES

       Generate a graph from codec.txt in PNG format:

	      codecgraph -f png codec.txt

       Generate a graph for the local host HDA codec data:

	      codecgraph
