I recently purchased a HiFiBerry DAC+ DSP and after initial setup and configuration, everything seemed to be working. However, after a few tests, I noticed that the signal I am receiving on the Toslink input is being cut off by half a second every time a song starts playing, which. I already tried two different sources (Cocktail Audio X12 and Oppo 103D), with Flac and MP3 files, and the issue is the same, no sound from the start. I have a stand alone DAC and never experienced this before. Also, I noticed that when the track changes, the green light of the optical input shuts off and only lights up again after the track is already playing. Is there a way to avoid this? Maybe it is a basic answer but I'm very new to this.
