I asked Jussi this question a few weeks ago and got the following answer:
Hi,
That is common problem with DoP and DACs that don’t follow DSD
specification closely enough. The specification requires DAC to mute
output for 50 ms when DSD stream is starting and when it is ending to
avoid such noises.
HQPlayer does play silence at beginning and end of playback. But not
between tracks. Make sure you have either PCM or SDM output mode
selected (instead of Auto) in main window so that DAC stays at either
mode and doesn’t keep switching between the modes…
Best regards,
