Public bug reported:
[Impact]
The headphone jack may not be detected after a warm reboot on systems with a
Realtek ALC3359 codec on Dell Intel NVL-H platforms. Audio can continue through
the wrong output.
[Fix]
Check the codec function status before reloading its initialization table.
Trigger jack detection when the jack callback runs, and retry the detection
interrupt if the sound card is not ready yet.
Upstream commits (no released v* tag contains them):
• be190d999369 — avoid re-initialize the blind write
• e8f30155e96a — trigger JD when system reboots
[Test Plan]
Connect a headset and run sudo reboot .
Without the patches: after the warm reboot, the headset may not be detected.
With the patches: confirm the headset is detected and audio uses the headset
output.
[Where problems could occur]
Could break initialization or jack detection in the ALC3359 codec driver. If
the function-status check or interrupt retry is wrong, the codec may not
initialize or the jack state may remain stale after reboot.
