None of the solutions above work for me. I don't have a dock, just the
headset jack on T440p.

Title:
[20ANCTO1WW, Realtek ALC3232, Black Headphone Out, Left] No sound at
all when headset plugged in
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
Sounds works fine through the internal speakers, but once I plug a
headset or headphones (I tried two things, in case one was broken) in
to the audio out, I get nothing.
Looking in alsamixer, plugging the headset in mutes the 'Speaker'
output and unmutes the 'Headphone' output, and restores the Master
volume to its previous headset-in value. Unplugging the headset does
the opposite (mutes 'Headphone'; unmutes 'Speaker'), as I would
expect.
This was working on vivid, so a definite regression, I think.
