Graphic Equalizer plugin: HifiBerry DAC+ Pro led always on

I have a RPi 3B+ and a HifiBerry DAC+ PRO RCA version hat.
The graphic equalizer plugin does work, but I’ve noticed that the DAC board green led is always on even when no track is playing, as if the DAC chip was always powered. Could this result in significant increase in average power drawing, as my RPi is always on but it actually plays a few hours a week, and if so, is there any way to keep both the plugin on and the normal behavior (i.e. led off when nothing is playing)?

Thanks.

Same here, led always on, no sound on RCA on a hifiberry dac +
