When this problem happens, we check the /proc/asound/cardX/eld#N.M, we will find the monitor_present=1, eld_valid=0. The root cause is BIOS or GPU driver makes the PRESENCE valid even no monitor plugged, and of course the driver will not get the valid eld_data subsequently. In this situation, we should not report the jack_plugged event, to do so, let us change the function hdmi_present_sense_via_verbs(). In this function, it reads the pin_sense via snd_hda_pin_sense(), after calling this function, the jack_dirty is 0, and before exiting via_verbs(), we change the shadow pin_sense according to both monitor_present and eld_valid, then in the snd_hda_jack_report_sync(), since the jack_dirty is still 0, it will report jack event according to this modified shadow pin_sense. After this change, the driver will not report Jack_is_plugged event through hdmi_present_sense_via_verbs() if monitor_present is 1 and eld_valid is 0.
