Hi,
I have a Pi-3b with a Hifiberry-DAC+ and they both worked well until recently. I can not get any sound out of the DAC+ anymore...
I have tried several things, as follows, with no success...
I also tried to boot the system on hifiberryOS and got no sound neither...
Does this mean the DAC+card is dead ?
Is there anything else I can try or look for ?
