Hi Mark

Thank you for checking patch

Sorry. what is this "limited functionality" mean ?

We used headphone output by ak4642/ak4643 on our (old) board.
today, our new board use stereo-line output by ak4648.

And ak4642/ak4643/ak4648 can output headphone/stereo-line in same time.
I think there is no limited functionality on these chips.
but am I misunderstanding ?

Best regards
