Hi officialsm
The disabled mixer does not seem to be a problem. I usually use an I2S DAC with software volume. Without changing the audio copy configuration, I changed to mixer type disabled (0db outout), and the spectrum worked fine. I then plugged in a USB DAC and tried the software, hardware and disabled mixers, and in all cases the spectrum worked fine without any changes to the audio copy configuration.
That led me to review your ouput again, and I think I have found the problem!
You are running mpd_oled without specifying the loopback device as the audio source. In which case, make sure you do not have a copy of mpd_oled running and then run
