Thinkpad T440s dock - no audio ALC292 Power: setting=UNKNOWN, actual=UNKNOWN, Error, Clock-stop-OK, Setting-reset

[CannyDuck]

If my Thinkpad T440s is connected with the docking station and the audio cable is plugged in the dock there is no audio output on the speakers. If I connect the audio cable directly with the Thinkpad I can here the audio output.

Hello all,

im using Ubuntu 14.04 with my T440s and the Pos Diock. I also can't get any audio output through the dock. But audio output on the build in speckers and on the jack on the laptop body works fine in case the laoptop is not docked....

So the problem Canny reported is still an issue, also in 14.04.

Looking at https://bugzilla.redhat.com/show_bug.cgi?id=1101386
We may need to backport http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/?id=1c37c22332a2d2c1b4ab32177a4f847c7fe06e38

[Lukas (bobukas)]

I attached a patch to bug #1385680 which solves extends the fix to the thinkpad x240.

[imker (imker)]

Hello all,

since I upgraded to Ubuntu 14.10 the audio output and input over the dock works fine.

Thanks
