    ALSA: hda - fix an external mic jack problem on a HP machine

    ON the machine, two pin complex (0xb and 0xe) are both routed to
    the same external right-side mic jack, this makes the jack can't work.

    To fix this problem, set the 0xe to "not connected".

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I'm not sure if it's fixed or not.
On the machines there are 2 slots, one icon on the machine is head phone, and another icon is microphone.
With the dkms, plug-in the microphone into the microphone jack, in the audio settings the input device will switch to external microphone.
With the proposed kernel, plug-in the microphone into microphone jack, nothing happens, but plug-in into head phone jack, it works.

I've tested headset and pure microphone and plugin to the microphone jack, the behavior is the same, with dkms it works, but with preposed kernel, nothing happens. It looks like the only working jack is the headphone jack.

This commit came from an upstream stable update. We don't need to verify those.

This bug was fixed in the package linux - 3.13.0-37.64
