Need your help on DSD over DoP on AUDIOPHONICS I-Sabre V3 DAC ES9023:
I installed this DAC on DietPi as HiFiberry DAC
It is recognised
root@DietPi:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 
Subdevice #0: subdevice #0
Installed ALSA utils
Installed FFmpage tools
It’s found in Roon as RAAT, plays 24/192, and plays DSD if converted to PCM.
However, I can’t get it to play DSD over DoP (even when DoP selected and it shows DSD64 in green).
I only hear hissing sound and in background very very very silently the music???
What’s missing, what’s wrong?
