Package: linux
Severity: normal

The docking station headphone plug stopped working after upgrading to 3.16. The problem matches the description for T440 which can be found here: https://bugzilla.redhat.com/show_bug.cgi?id=1101386
But in my case it stopped working after the patch https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda/patch_realtek.c?id=1c37c22332a2d2c1b4ab32177a4f847c7fe06e38 was applied
expected:
* headphones/speakers get plugged in
* sound on the speaker is reduced and the headphones output is activated (pulseaudio magic?)
what happens:
* headphones/speakers get plugged in
* no mixer changes
* I cannot hear anything anymore
Interestingly, it works fine when using the headphone plug on the laptop instead of the docking station. But in my setup I cannot use the laptop plug because the speakers are all the time connected to the docking station.

Hi
This bug was filed for a very old kernel or the bug is old itself
without resolution.
If you can reproduce it with
- the current version in unstable/testing
- the latest kernel from backports
please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Regards,
Salvatore
