The main problem is the "pink jack" and "blue jack" at rear panel can be
retasked as output pin for those motherboard with 3 audio jack at rear panel
(e.g. those VIA codec has "Smart51" switch

Some realtek codec has "Line/Mic jack mode" or "Mic Jack Mode" controls

How about those laptop docked into a docking station ?

Did pulseaudio changed the profile from "Internal Mic" or "External Mic" to
"Dock Mic" automatically
