Two front mics can't work on a lenovo machine

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1740973

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

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-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

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.

Thanks Hui. It looks like you found a few more Lenovo machines that need this fix.

As well a going into the currently under development 4.18 kernel, the new patch is in the 4.17.4 kernel:

commit 11a74cf5d322b899c95a1544e4ed85b5712babc1
Author: Hui Wang
Date: Mon Jun 25 14:40:56 2018 +0800

    ALSA: hda/realtek - Fix the problem of two front mics on more machines

    commit e41fc8c5bd41b96bfae5ce4c66bee6edabc932e8 upstream.

    We have 3 more Lenovo machines, they all have 2 front mics on them,
    so they need the fixup to change the location for one of two mics.

    Among these 3 Lenovo machines, one of them has the same pin cfg as the
    machine with subid 0x17aa3138, so use the pin cfg table to apply fixup
    for them. The rest machines don't share the same pin cfg, so far use
    the subid to apply fixup for them.
