Bug description:
[SRU Justification]
[Impact]
When output device is set to HDMI/DP and headset plugged in, there is no
Headset device available in sound settings.
[Fix]
Proposed fix in
https://patchwork.kernel.org/project/alsa-devel/patch/[email protected]/
, already accepted as
https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?id=94d508fa3186d0cbc63765aa94d5cf3bd847694c
. This also depends on two commits which already in mainline kernel that
refactor device init.
[Test Case]
1. Set output device to HDMI/DP
2. Plug headset
3. Check Sound settings for a new headset device
[Where problems could occur]
The last patch simply makes the onboard audio jack to use phantom jack.
No much potential risk introduced. The two prerequisites simplifies
init procedures and may need to receive some more stress tests
especially those for suspend/resume, plug/unplug.
[Other Info]
This is for the new oem Dolphin platform that is only available in
oem-5.13/oem-5.14 and impish. See bug 1939541.

1. Check output device is HDMI/DP audio and it works

Sound settings has no headset
