Public bug reported:
Hi everyone,
when I dock my Thinkpad T440s to my docking station, the sound channel
for the speakers connected to the docking station audio jack are muted
by default. If I run the following command after docking
amixer --card 1 sset 'Speaker+LO' 100%
the sound starts
you have to file upstream bug report
And where?

Title:
Thinkpad T440s - Sound muted when docked to docking
And the speakers are connected to the 1x Stereo/Mic Combo Audio Port
mentioned in the device specification of Lenovo. Nothing is connected to
the audio port directly at the laptop (that works fine by the way).
