Thanks. So, something still doesn't trigger at unplugging. We should check at
first whether the jack-detection really works reliably.
Install hda-verb from OBS home:tiwai/hda-verb repo, and check whether the
pin-detection works or not. Run like below at HP plugged / unplugged.
# hda-verb /dev/snd/hwC0D0 0x21 GET_PIN_SENSE 0
You should have different value in the bit 31 when plugging / unplugging the
headphone, 1 = plugged, 0 = unplugged.
If the above is confirmed to work, what we can do at next is to use
trace-points.
Check whether /sys/kernel/debug/tracing/events/hda directory exists. If yes,
run like:
# echo 1 > /sys/kernel/debug/tracing/events/hda/enable
Then plug/unplug the headphone. Copy the tracing result by
# cp /sys/kernel/debug/tracing/trace SOME-YOUR-FILE
where SOME-YOUR-FILE is an arbitrary file name to save. Attach this file
content. After getting the result, echo 0 to the same sysfs file above to
disable the tracing.
