I have a Pi zero with a sd card flashed with Volumio music program, and a PhatDac fitted onto the GPIO pins, Up until a week ago it all worked well with sound coming out of the PhatDAC into a speaker.
Then a few days ago, the sound was no more, so I assumed it was the PhatDAC, and bout an AudioDAC to replace it. I tried that, and still no sound. I then tried another Pi Zero and no sound from there either.
Anyone any idea what could be the problem Pi Zero, AudioDAC, PhatDAC, or even the sd card.
Thanks
