Hi @benjamin!
PRO-JECT support team AUSTRIA have provided me OS Volumio distr. v 1.071 and the instruction how to install it ((Pro-Ject Stream Box S2 Ultra: Multiple Issues with Roon - #26 by Leonid_Kravchuk). With streambox as a ROON bridge everything is resolved for now.
Meanwhile.i have asked additionally about dissapering NATIVE DSD scenario and DoP as well in ROON Settings starting form sofware VOLUMIO OEM v. 1071. With sofware of VOLUMIO OEM v. 1.069 (‘from the box’), as i remember streambox s2 ultra and connected DAC SA KI RUBY has NATIVE DSD scenario options in ROON SETTINGS (as well as additional hardware mixer settings). But in v.1071 nither Native DSD (which is preferable), nor DoP settings are simple not working, and ROON reflects DSD 2.8Mhz sent as PCM 352 Mhz. That’s it!(
I am kindly ask you to clarify this issue by your channels with PRO-JECT support.
Thank you in advance!
Warm regards,
LK
