I have a Fujitsu Lifebook T4210 (very similar to the T4215) and wish to work on adding support for these models in patch_sigmatel.c. I have ran the alsa-info script, once after a fresh boot, and once after changing the model a few times:
Virgin: http://www.alsa-project.org/db/?f=e76430dbf61b0e2c1ff199c9d1c85051a0341508 With Model Changed: http://www.alsa-project.org/db/?f=cdd45e343c143052e18f9706e65eef8865696606
After trying various models, I have been unable to get the audio to output to the correct pin groups. I have managed to use hda_analyzer.py to change some of my hardware settings, and have an idea of what verbs i need to send. What I need is some information on the architecture of the driver, or an idea of where to edit things. I would just say the config here and ask someone else to edit patch_sigmatel.c, but this is only the first of the issues I want to fix, so some knowledge of how to edit myself would be useful.
