Hello, all.
Recently got a Digi+ Pro HW1.2 and had a "MPD error | Failed to open ALSA default | Failed to open ALSA device hw:1,0 | No such file or directory".
After some back and forth, realised that setting I2S audio device to None solved the issue (as opposed to "HiFiBerry Digi+ Pro" or "HiFiBerry Digi(Digi+)").
I don't understand why this solved it, but thought it could be useful to others and maybe someone know what I did wrong.
Setup: Pi B v1.2, running from a 10A 5V switching power supply (into GPIO pins #4 and #6). Soldered a 2x20 pint header to the Digi+ Pro. Software is moodeaudio 6.7.1. Prior to the Digi+ Pro, I've used a USB-powered DAC Focusrite Scarlett 2i4.
Results from dmesg:
