RE: ear jack

It's hardware design. One pin of the earjack will high/low change when
plugging in/out the earphones.
You can refer to Page16.

As my experience, earjack wouldn't interact with audio driver. It only
effects the audio amplifier how to output the waveform, line-out or
speaker-out, through an indicating pin. Line-out is single-ended output for
earjack. Speaker-out is differential output for speaker.

ho w earjack interact with audio driver?
