[HP EliteBook 840 G2, Realtek ALC3228, HP UltraSlim Dock 2013] Line
in/Line out on docking station doesn't work
Status in alsa-driver package in Ubuntu:
When I plug in external speakers to line in/line out combo on the
laptop the internal speakers are turned off but when I plug the
speakers into the docking station (HP UltraSlim Dock 2013 EURO,
D9Y32AA) music keeps playing in the internal speakers. Similar
behaviour (nothing happens) is experienced with microphone connected
to line in on docking station.
### Expected behaviour
Plugging in external speakers to docking station should turn off sound from
laptop internal speakers.
Plugging in microphone to line in on docking station should switch
from "internal microphone" to "microphone" in Ubuntu sound settings.
### Current behaviour
Sound keeps playing in internal speakers when plugging in external speakers
to docking station.
Plugging in microphone to line in on docking station, nothing happens.
