[PROBLEM] witch Audio Playback at the begin of the Track

[Nutul]

The OP hasn't told us what the actual DAC is in his setup. The HiFiBerrry Digi2 Plus isn't a DAC; it merely converts the PCM parallel-bit transfers to S/PDIF serial-bit streams. There's an interesting note on Limitations in the Wikipedia article on S/PDIF which comes into play here. I have no experience with S/PDIF equipment so can't comment further.

It would still seem useful for us to example one of the OPs albums for any oddities, but that's on him.

Good point Kent.

Looks like the DAC following in the chain might be more responsible. Since it then continues to play fine, I would exclude a bandwidth limitation dictated by the SPDIF standard.
Nevertheless, see if the OP comes back.
