Can't adjust volume on app or in PC, trial version

USB cable from PC to main system with Lampi DAC/Amamero . Just speakers (Combo 384 Asio 1.3) as device name.
Asio driversetup in grey.
No volume slider on app on PC. PC volume does not work.
Volume slider on Android app. Does not affect volume.
No slider on Ipad app.

Have you enabled software volume control? Can you dump the debug info here?

Yes. I’t on.Audirvana 3.5.41

You need to disable the upsampling to DSD.

Thank you. It works. What’s the best option in the upsampling box? I guess to 192? Do people prefer PCM or DSD with this app?

It’s a question of personal taste, DAC you’re using and more importantly, the type of music you’re listening and if it’s available in DSD.
