Built and fired up on my first Raspberry Pi this morning and had Caldera running headless in about 2 hours. Raspberry Pi 5 with 2GB ram and a 32GB SD plus a DAC+. Memory usage appears to be just under 0.5GB of ram total for the system and no problems with cooling without fan. CPU and GPU usage is pretty much non-existent.
One question, how do you control the equalizer on Caldera? The Plexamp app settings don’t appear to change anything for Caldera’s playback.
