When I pick a dac to use, hifiberry DAC plus doesn’t work. Doesn’t load, no sound. But if I select hifiberry DAC (plain) it works ok. I’m using a Pi Zero with the hifiberryDAC+Zero. Am I missing something? Any pointers would be appreciated.
I wouldn’t worry: if you have found a device overlay that works, then use it. The difference between DAC and DAC+ for RPI and RPi Zero are not necessarily the same.
