SSM3582, speaker output stops when operating one-side DAC OFF/ON.

On the SSM3852, I encounter unexpected behavior.
Could you please check below?

When setting the one-side DAC channel OFF and setting ON again, the speaker output stops with the over current.
On the evaluation board, we can reproduce the behavior.
Are following operations unexpected on the SSM3582?
When controlling the on-side DAC channel ON/OFF, does it cause any errors (for example, current leakage occur)?
