Speaker power management setting

Hi everyone.

There is a noise when voice trigger the speaker.
I found that uncheck the power saving mode will help this issue. Like the following figure.

But when I restart the Windows it will go back to the default setting every time.
The strange thing is that you shutdown the Windows and turn on by the button. It will keep the last setting.

Dose anyone has the idea about this??


Thanks.
