Volumio, RP3/4, Digi+ Pro: Lot's of clicks when not playing

Hi HifiBerry-friends,

using Volumio, I have a lot of high-pitch clicks on my speakers when no music is playing using the SPDIF. Happens on Raspberry Pi 3 and 4. Interface is the Digi+ Pro. I tried two of them. The amplifier is a Hypex PSC2.400D connect via cinch output to the digital XLR AES input.

Also I tried a Tinkerboard with the onboard SPDIF. That's working fine.

Any idea, how I can avoid the clicks? I already tried the jumper on the HB Digi.
