Description of problem:
jack sense doesn't work correctly on Lenovo Thinkpad T510 resulting in speakers or headphone output being zeroed and muted for whole system run time

Version-Release number of selected component (if applicable):
kernel-3.12.6-300.fc20.x86_64
alsa-firmware-1.0.27-2.fc20.noarch
alsa-plugins-pulseaudio-1.0.27-2.fc20.x86_64

kernel-3.11.10-301.fc20.x86_64
kernel-3.12.5-302.fc20.x86_64
alsa-lib-1.0.27.2-2.fc20.i686
alsa-utils-1.0.27.2-3.fc20.x86_64

How reproducible:
always

Steps to Reproduce:
1. download to a single directory these files: hda_{codec,mixer,proc}.py files from alsa git [1] and the hda-jack-sense-test [2]
  [1] http://git.alsa-project.org/?p=alsa.git;a=tree;f=hda-analyzer;hb=HEAD
  [2] http://mailman.alsa-project.org/pipermail/alsa-devel/2011-May/039809.html
2. cd to the directory, chmod +x hda-jack-sense-test
3. run ./hda-jack-sense-test docked and undocked
4. run "./hda-jack-sense-test -a" for all combos of port connections and laptop docked

Actual results:
3. only these pins are shown in spite of dock mic+hp out jack (in)availability:
Pin 0x19 (Black HP Out): present = No
Pin 0x1b (Black Mic): present = No

4.

Pin 0x19 (Black HP Out): present = No
Pin 0x1a (Not connected): present = No
Pin 0x1b (Black Mic): present = No
Pin 0x1c (Not connected): present = No

Pin 0x22 (Not connected): present = No
Pin 0x23 (Internal Mic): present = No

Expected results:
  * dock station jacks are recognized as such (availability, color)
  * microphone of hp+mic combo sensing works correctly (the input gets switched correctly though so some hw switching probably is at work)

Additional info:
  * debug info is in the attachment
  * the problem may be the root cause of the bug 1006791 in RHEL 6
Comment 1 David Jaša 2014-01-08 16:28:50 UTC 
Addendum:

1) plugging/unplugging headphones in integrated laptop jack works fine - output of speakers/headphones gets muted/unmuted and unmuted/muted respectively

2) plugging/unplugging headphones to/from dock jack has no effect in mixer

3) docking station jacks don't show up in './hda-jack-sense-test' output but in /proc/asound/card0/codec#0, they are described just fine:

Comment 2 Justin M. Forbes 2014-02-24 13:56:21 UTC 
*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs.

Fedora 20 has now been rebased to 3.13.4-200.fc20.  Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you experience different issues, please open a new bug report for those.
Comment 3 David Jaša 2014-02-24 14:37:00 UTC 
In the 3.13 kernel, the Speakers/Headphones controls are missing so even though the underlying issue (hot-plugged physical jacks on dock not recognized as such) persists, it's user-visible part is gone.

Closing as WORKSFORME because when the jack sensing is reenabled again, this bug will regres.
