Comment(by joerg):

 Internal power management of ALSA WM8753 driver enables and disables
 MICBIAS depending on setting of control.66.
 MICBIAS triggers HOLD.

 When pressing and holding down HOLD-button of an attached headset, IRQ
 generation and screen wakeup via control.66 as well as 'alsactl restore'
 is stopped.

 Masking HOLD-IRQ by tracking JACK_INSERT seems to be the best way fix this
