TLV320AIC3104: Pin handling issues

Part Number: TLV320AIC3104

Hi TI,

I am interested in using Audio Codec IC.
I am wondering how to handle the output pins below because the Audio Out is missing in the new model.
 
Please check whether you need to tie it to the ground separately or handle the pull-up, etc., and reply to it.

    Hi, BJ Han,

    The unused analog outputs such line outputs (RIGHT_LOP/M, LEFT_LOP/M) and headphone outputs (HPRCOM/HPROUT, HPLCOM/HPLOUT) can be left floated if they are not in use. There's no need to connect an additional component or tie them to GND or VDD.

    Best regards,
