"Capabilities: volume"

...means a volume control that affects both playback and recording. So 
that looks ok.

Orschiro should have both an "Internal Mic" port and a "Docking Station 
Mic" port, and be able to select the "Internal Mic" one. From the pacmd 
ls it doesn't seem to be that way. This is probably a bug, but since no 
more releases of 0.9.23 are planned, I wouldn't spend time on it unless 
it is also a problem in 0.99.x.
