I have A HifiBerry DAC on a Pi running volumio 1.41. Yesterday I tried playing and I got no sound. In Volumio, I can only see the ALSA output device. Trying to do anything with the DAC driver resulted in a 'background worker is busy' error.
I reimaged the SD card and I still have the same result. Therefore I suspect that the DAC may be the problem.
Can you suggest how I proceed?
