SND_JACK_HEADPHONE | SND_JACK_MICROPHONE |SND_JACK_BTN_0 | SND_JACK_BTN_1 |SND_JACK_BTN_2 | SND_JACK_BTN_3, jack, NULL, 0);Do you really support all those buttons?
TI driver supports 4 buttons sound/soc/codecs/ts3a227e.c google made 4 buttons headsets
Not every codec is capable of handling 4 buttons. That TI codec was made specifically to detect 4 different levels of impedance. Looking at the Max98090, I see support for a single button press (change in the status of JKSNS). what makes you think you can handle 4 buttons in the codec hardware?
