Good settings to play DSD to DSD from Roon to HQP

I had forgotten that I had some DSD64s and so I am hesitant about the correct configuration of Roon before HQPlayer (Sigma decoding before SDM reencoding ?).
I am not in direct DSD (in HQP) because I manage the volume.

And 2nd question… why all the screenshots I see are “HQPlayer streaming”, while at home, it stays at “HQPlayer” ? Just a translation problem ? or something else ?

You should disable these Roon side DSP things like volume leveling, so that Roon passes DSD untouched to HQPlayer.
