Adjust volume after TI PCM1742 DAC?


Hi All,
A box audio output is TI PCM1742 DAC, I want to connect to low
power speaker ( thin speake ) and I also want the volume is adjustable.


Do I have to add chip ?


or can I only add variable resistor to function that?


1. I have two channels.
2. The resistor can only decrease volume, right? our digital domain
audio signal to DAC already set to maximum, but I feel it is not loud
enoguh.


Could you please advice the method to adjust two channels volume
directly, or advice a chip that is suitable to connect after 1742?


Best regards,
Boki.
