ALSA: hda: Jack detection poll in suspend state
HDA Jack detection logic doesn't work when the HDACODEC in runtime suspended state as unsol event won't be triggered during D3 state. As pulseaudio server in userspace rely on the jack mixer control status to show the audio devices in gui and any display sink device hotplug event during D3 state will never updates the jack status which will result in no audio device option available in userspace settings. The possible option available to resolve this issue is to run Jack polling worker thread even after codec suspend state. The choice can be made based on compromise between power saving or Jack detection in suspend state.
