I alredy described my problem in my first message in presentation section, but after a first response I have received no replies to subsequent messages. I try to repeat here the answers,
I use a Pro-Ject Stream Box S2 Ultra connected to a North Star Design Supremo dac, but Volumio seems unable to recognize that my dac handles native DSD streams up to DSD256.
In my first post I sent the data of my dac and Michelangelo replied that the dac was added to the list of dacs capable of managing the NativeDSD, so with the subsequent system release of the Pro-Ject Stream Box the problem would have been resolved.
Since then, June 2019, there have been 3 or 4 updates of the system of Pro-Ject Stream Box, now we are at n. 1.043 released Tue Sep 23 03.05.08, but nothing changed:
- if i set Native DSD --> the DSD flows are automatically converted to PCM 352 kHz;
- if I set DoP DSD --> DSD64 and DSD128 work correctly, DSD256 is still converted to PCM 352 kHz.
What I shall do to resolve the problem?
I could change the Project Stream Box with a bridge mini pc with Windows10 and ASIO driver of my DAC, but I would prefer to solve the problem by keeping the Stream Box.
