I try to get my Digi+ to work with Kodi. Running Raspian Jessie. Followed the steps described for Kernel 3.18.x.
Everything fine, the Output of aplay -l Looks the same as in your guide.
But in Kodi all I see in "Audio output device" is snd_rpi_hifiberry_digi Analog" and not "snd_rpi_hifiberry_digi S/PDIF". For the passthrough device there is noc choice at all, only "PI: HDMI". The only sound I get is Stereo if I turn off passthrough.
Any idea somebody?
