Hi. T420 here, Debian 8 and same output i.e: 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)

sometimes when I plug and unplug headphones it mutes the speakers (or changes devices) so I have to go through settings... hope that's it?
