I've set up headphone hack detection in my machine driver, using snd_soc_jack_new, snd_soc_jack_add_pins, and snd_soc_jack_add_gpios.
I've also created a control to allow the user to enable/disable the headphone jack:
static const struct snd_kcontrol_new harmony_controls[] = { SOC_DAPM_PIN_SWITCH("Headphone Jack"), };
On their own, both of these work fine.
However, if I use the control to disable the headphones, then unplug/replug the headphones, the jack detect seems to override the control, and I hear audio from the headphones.
Is this something that's known not yet implemented or was never intended to be used this way, or should I look further to find the issue?
FYI, sound/soc/samsung/smartq_wm8987.c has this same code structure, and I imagine will have the same issue.
Thanks.
