CODECGRAPH(1)
π CODECGRAPH(1) β the hda-intel codec graph generator π
okay bestie, listen. this is the codecgraph manual page, from the HDA tools family, and it's genuinely one of those little utilities that eats. no cap. it's a tiny program with four flags and it will hand you a whole picture of your sound chip's insides. let's get into it π
β¨ NAME β¨
codecgraph β hda-intel codec graph generator
π¦ SYNOPSIS π¦
codecgraph [-f format] [-h] [-o name] [-v] [codecfile]
πΈ DESCRIPTION πΈ
so here's the tea: codecgraph generates a graph based on the ALSA description of a High Definition Audio codec. that's it, that's the whole job, and it does it gorgeously π
the generated graph depicts the HDA codec layout and all the node connections, which is lowkey a lifesaver for driver troubleshooting and maintenance. like, instead of staring at a wall of hex and guessing which widget talks to which, you get a picture. main character energy honestly.
and on Linux, this description lives right here:
/proc/asound/card*/codec#*
go look, it's there, i promise π«Ά
π OPTIONS π
-f formatβ specify the format of the generated graph. valid formats are all formats accepted bydot(1), which includesps(PostScript),svg(Structured Vector Graphics),fig(XFIG graphics) andpng(Portable Network Graphics). so basically whateverdotcan do, you can do β¨-hβ show usage information and exit. the classic "wait how do i use this" button π-o nameβ set the output file name. name your baby π-vβ print version information and exit.
π EXAMPLES π
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
look at that second one. no arguments. no file. it just knows. iconic behavior, periodt π₯

heads up bestie: the-fflag hands your format string straight todot(1), so ifdotdoesn't know it, neither doescodecgraph. keep it to the formatsdotactually accepts and you're golden π«
and that's the whole page!! Version 1.0, dated Jan 2008, from the HDA tools crew. go graph your codec, bestie, you've got this π β¨π
