[Hui Wang]

From: Kailang Yang <kailang at realtek.com>

BugLink: https://bugs.launchpad.net/bugs/1810891

If it plugged headphone or headset into the jack, then
do the reboot, it will have a chance to cause headphone no sound.
It just need to run the headphone mode procedure after boot time.
The issue will be fixed.
It also suitable for ALC234 ALC274 and ALC294.
