Look at the .state files in /usr/share/openmoko/scenarios/ with nice 
descriptive names. You can use diff to see what changes between the different 
states, and you will want to edit these to make the changes persistent. I'm 
still working this out using these and the audio path diagrams on the wiki.

The mics in particular have several adjustments in the audio path. I _think_ 
it's something like this:

Both handset (mic1) and headset (mic2) mics are switched by 'Mic Sidetone Mux' 
into the channel that passes though 'Mono Sidetone' and 'Mono' volume 
controls.

headset earphones and speaker are on 'Headphone'

Handset earpiece is on 'Speaker'
