Audirvana on Mac mini 2014 does not recognize a 11.2 MHz DoP capable DAC as DSD DAC

DAC is Esoteric Grandioso K1X which is 11.2 MHz DoP capable.

Both 3.5 and Origin on following MacBook Pros work fine;
MacBook Pro (16 inches, 2021), Apple M1 Pro, 16GB, macOS Monterey 12.4
MacBook Pro (Retina, Mid 2012), 2.3GHz quad core Intel Core i7, 8GB, macOS Catalina 10.15.7

But on Mac mini (Late 2014, 2.6GHz Dual core Intel Core i5, 8GB, macOS Monterey 12.4) they fail to recognize the DAC’s DoP capability and send PCM data.
Using Esoteric HR Audio Player software, it has been confirmed that this Mac mini can send DSD to the DAC.
To check if there are malfunctioning softwares, I have tried Clean Re-installing of Monterey to no effect.

Any suggestions?

Hello @nrrc,

When you go in your audio output setting, do you have the option to set the DSD over PCM to 1.0?

Thank you for the suggestion. By choosing the DoP option in Audirvana 3.5, DSD has become effective. Somehow it automatically reflected to Audirvana Origin.
