The patch is sent to oem-5.10 first, and other ubuntu kernels will
merge this patch with stable update since this patch was already
CCed to stable.

Users plug a headset or microphone to the front mic jack, but the
system can't detect the plug and will not set the mic to be the
active input device.

Backport a upstream patch, this will change the front mic jack's
name from Front Mic to Mic, then the pulseaudio could handle the

Plug a headset to the front mic jack, open the gnome-sound-setting,
the front mic is the active input device, use this device to record
sound, it could record the sound successfully.

[Where problems could occur]
It could make the other mic can't be detected, but this possibility is
very low and I alreaed tested all audio jacks on that machine, all worked
well as before.
