I just bought a DIGI+ card for my RaspberryPi 3B. After connecting it and following several guides on how to configure it with OSMC and Volumio I couldn't get it working.
Looking on this forum i found this post: https://support.hifiberry.com/hc/en-us/community/posts/115002769469-My-Digi-doesn-t-work-anymore?flash_digest=9358d26f273db7644e4633616fc5b73ba512be11#_=_
After following the instructions, installing the image, executing the command 'play -n synth sine 1000' I hear nothing from my speakers.
Also I see no (red)light on the SPDIF, shouldn't this be lighting up?
Secondly, there is a green led burning on the board, so I assume its getting power etc.
What could possible be wrong and how can I determine if the board is (not) functioning?
