Same here, Gigabyte GA-B250M-DS3H with HDA Intel PCH, ALC887-VD. Ubuntu 18.04.
On my machine, once this starts happening it survives a reboot but goes away for a while after a _cold_ reboot. Clicks every few seconds and debounce might indeed be a workaround (~20 ms plug/unplug in my case): $ ./pulseaudio -vvvv --log-time=1 2>&1 | grep -P 'Front Headphone.*is now' ( 0.120| 0.000) D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged ( 3.134| 0.000) D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in ( 3.155| 0.000) D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged ( 5.161| 0.000) D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in ( 5.182| 0.000) D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged ( 6.324| 0.000) D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now plugged in ( 6.345| 0.000) D: [pulseaudio] module-alsa-card.c: Jack 'Front Headphone Jack' is now unplugged I'm yet to see anything other than 21-22 ms. I set jackpoll_ms=40 in snd_hda_intel options but still seeing the same plug/unplug interval.
