For those interested in Linux HDA sound troubleshooting, Eduardo Habkost’s Codecgraph tool finally gains a tarball and page.

Codecgraph is a tool to generate 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. Codecgraph’s parser reads the codec description from /proc/asound/card*/codec#0 and parsed data is sent to Graphviz for actual graph generation.

I mentioned codecgraph before as the tool used to fix 5.1 sound in six and threestack ALC888-based HP systems, and recently it was used to fix 5.1/7.1 sound in the Dell Inspiron 530.
