Setting up HQ player with Holo red

Folks, I am very new to this and need some help here.

I got a separate PC to run HQ player and Roon server. I have Holo Red and Holo may DAC feeding into other gear. I can’t find any step by step instructions on how to setup everything. I have installed roon and HQ player and connected them.

I saw Holo red manual talking about flashing the red with some image files of HQ player ? Currently I have accessed red os server and chose HQ player as NAA. The music through roon/tidal is playing on HQ player but no reaching red/Dac… I think I am missing something …

Should I get a new SD card to flash the software or the one that came with RED that has RED OS installed…

Thanks…

Did you set the output in HQPlayer setup to be NAA and then selecting the RED from the Device dropdown.
