how do you edit hda pins and nodes?

Hello,

I have a Thinkpad R61i with the Conexant CX20549 HDA codec. A lot of the controls are wrongly wired, with showstopping consequences, such as not being able to change the mic capture level, resulting in intolerable distortion.

To get round this I rolled my own kernel with hwdep enabled and used hda-analyzer to tweak what had to be tweaked. Unfortunately hda-analyzer would always download its own latest version from git, and right now the version in git is broken. I have tried a snapshot of an older version, but that doesn't work either. Therefore I am going to need to do this manually.

I can see the values I need to change in /proc/asound/intel/codec#0. The trouble is that I cannot for the life of me work out how to change them. Could anyone help me?

Many thanks
Robert
