Do your dock station has one headphone and one mic Jack or just one combo
headset Jack ?
Connect headphones or a headset that has a 3.5-mm (0.14-inch), 4-pole plug
to the audio connector to listen to the sound from the computer.
Remove the following lines
> options snd cards_limit=1
> #options snd-hda-intel model=thinkpad
> options snd-hda-intel model=thinkpad enable=1 index=0
> options snd-hda-intel model=hdmi enable=1 index=-2
lenovo-dock expect dock headphone Jack and dock Mic Jack ?
Post the output of alsa-info.sh when thinkpad is docked and not docked with
headphone pluggedd and unplugged
