NAME

       codecgraph - hda-intel codec graph generator

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 layout and node connections,  helping  driver  troubleshooting  and
       maintenance. In Linux this description is available at /proc/asound/card*/codec#*.

              Specify  the  format  of  the  generated  graph. Valid formats are all formats accepted by dot(1),
              including ps (PostScript), svg (Structured 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
