When we have a mono input, do we really want to have the same input doubled? I don't do any recording, so I don't know how most programs handle this, but IMHO it's a waste of resources and if the source is only able to deliver a mono-signal, the recording should only be possible in mono. Does this sound sane? Be warned, if you proceed to submit such patches, we may want to lure you into becomming a committer...
