I experienced the same problem on Lubuntu 14.04 (automatic switching to front mic, although no front mic connected). This workaround fixed the problem for me as well.
Here some more thoughts: - The problem occurred less often on my pc if I decreased the speaker volume (internal feedback from speaker to unconnected front mic?) - If this is not strictly a bug (might depend on hardware) there should still be a GUI option (pavucontrol) to disable autoswitching without having to go through config files - In pavucontrol you can enable "Set as fallback" for each input (in my case front and rear mic + line in), even though I disabled this for front mic it keeped switching back to this input (the flag would then be automatically set again).
