volumio + Hifiberry Digi+ pro question

Hi folks,

Is it possible to have a signal coming out of the digi + board even if there is no music playing. My DAC is giving a “ploc” each time music is restarting after a certain time. If songs are playing after each other I have no problem because the DAC is not losing the signal in-between .

If I well remember I didn’t have this problem with Volumio 1…

Thanks
