[PATCH 5.4 042/408] ALSA: hda/realtek - set mic to auto detect on a HP AIO machine

[Greg Kroah-Hartman]

From: Hui Wang <hui.wang@xxxxxxxxxxxxx>

commit 13468bfa8c58731dc9ecda1cd9b22a191114f944 upstream.

Recently we enabled a HP AIO machine, we found the mic on the machine
couldn't record any sound and it couldn't detect plugging and
unplugging as well.

Through debugging we found the mic is set to manual detect mode, after
setting it to auto detect mode, it could detect plugging and
unplugging and could record sound.
