Title:
alsa/sof: headphone can't be detected when sof driver enters
rt_suspend
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Eoan:
Fix Committed
Bug description:
This patchset is already in the linux-oem-osp1 and focal, so only eoan
kernel needs this patchset
[Impact]
When users plug a headset/headphone into the audio jack, the driver
can't detect them, if users open the gnome-sound-setting, then the
driver could detect them.
[Fix]
Before driver enters runtime_suspend, need to set the WAKEEN, then
the plug/unplugging will trigger unsol event to the driver.
[Test Case]
boot the kenrel, plug/unplug the headset/headphone, run amixer contents
to check the "Jack Headpone" state
[Regression Risk]
Low, those patches come from mainline kernel, I have tested those patches
on Dell and Lenovo machines, they all worked well.
