[SRU][Cosmic/Bionic/OEM-B][PATCH 0/1] The front MIC can't work on the Lenovo M715

Hui Wang
BugLink: https://bugs.launchpad.net/bugs/1797292

[Impact]
On the machine of Lenovo M715, there are 2 audio jacks on the front panel,
one of them is microphone jack. When we plug a micrphone into it, the system
can't detect this microphone and can't record sound via this microphone too.


[Fix]
Apply the quirk of ALC294_FIXUP_LENOVO_MIC_LOCATION, the alsa driver will
assign a different name to this audio jack, then pulseaudio can handle this
jack and everything works well.


[Test Case]
plug a microphone to this jack and record sound, system can detect the
microphone and can record sound.

[Regression Potential]
Very low, this pin configuration is specific to the machine of
M715 so far, will not affect other machines.

[SRU][Cosmic/Bionic/OEM-B][PATCH 1/1] ALSA: hda/realtek - Fix the problem of the front MIC on the Lenovo M715

Hui Wang
BugLink: https://bugs.launchpad.net/bugs/1797292

The front MIC on the Lenovo M715 can't record sound, after applying
the ALC294_FIXUP_LENOVO_MIC_LOCATION, the problem is fixed. So add
the pin configuration of this machine to the pin quirk table.

Maybe we should at least start to tag things not picked from the upstream linux
tree as "UBUNTU: SAUCE: "
