I'm trying to build an RPI4 streamer with my Peachtree Pre DAC connected without a HAT via USB.
I've got all of my streamer software built and it is (mostly, he says optimistically) working using Plexamp. Everything else about my Plex setup is working.
What is not working...I can't get any audio out of the RPI4 using USB on any of the four USB ports.
My Peachtree Pre DAC is set to USB 2.0 mode
Peachtree says I should see it advertised as "peachtree preDAC".
But I can't see it.
It doesn't seem to see this anywhere.
I'm trying to figure out what is wrong, but everyting I've tried doesn't seem to change these outputs.
My Plexamp configuration for output shows a bunch of options that are not the ones I want.
I am craving a nudge in the right direction. Thank you.
