Bit Rate issue: Rpi3 + Allo Digione + Holo Spring Dac v2

[sdiesel77]

Hi All
I am using the following config with PCP: Rpi3 + Allo Digione + Holo Spring Dac v2 (via coax)

I noticed that when playing some high res files such as DSF the DAC is not recognizing the full bit rate.

As an example on the below file 5644khz, the DAC shows 176 4k.

Any idea how to fix this issue?
Could it be the file format settings?

Does coax output support native DSD?

Dunno, I think so ..

I think SPDIF only supports DSD over DOP which is DSD over PCM. Only USB or HDMI supports native DSD.

You could try using the USB input to prove it.

Issue resolved!
Indeed DSD only working with USB.
I therefore upgraded to a Rpi4 (8gb)
No need for Digione anymore, USB direct from Pi4 to DAC and I have to say I'm really impressed with the sound quality improvement!
Thx
