DAC+ DSP Output stops after Reboot

I have got the DAC+ DSP Board connected directly to my Raspberry Pi 3.

I have installed the 4way-iir profile from Github. Output works fine.

If i reboot/start the system and start playing Music, there ist just a very short Output of music (about 1/2 second) then the music stops and the green LED on the DSP turns off.

Writing the profile to the DSP again using dsptoolkit install-profile or Sigma-Studio (Self-boot Memory -> Write Last Compilation through DSP) makes the Output work again.

What do I have to do, to make it work directly?
