I seem to recall that sometimes you have a hardware-only jack that does this. Sometimes its a software only thing where the hardware has a switch that the software uses to flip the output wiring. So depending upon the chipset and what it implements, it may be some automagic wiring done by the driver that's enumerated at boot time. Boot with -v and see if you get this nice verbose output from the sound driver explaining how all the connections are wired up. -adrian On 19 November 2013 06:23, Julian H.
