the Symptom is the headphone was reported plug and unplugged in the loop in the pulseaudio verbose log

the exact cause of the problem is not known, you have to enable tracepoint to find out why unsolicited event was triggered

or the jack detect is inverted

by using hda-verb GET_PIN_SENSE after you disable the unsolicited event by set the misc bit of headphone or disable jack detect using hint jack_detect = 0
