Yes, you are right. On the buttons, someone would like to have an 
keymapping like KEY_VOLUMEDOWN, KEY_VOLUMEUP for the different buttons 
SND_JACK_BTN_X. This is always added to the jack by the ts3a227e driver.

I pushed yesterday a v3, which returns all supported jack types by this 
device. I am happy with this.
