I just received my AMP2 and plugged it into a fresh PI3.I run OSMC 2017.12 so now I want to connect the card. I followed https://www.hifiberry.com/blog/configuring-osmc/ to make it works.
I selected the hifiberry-dacplus as overlay, restarted the PI, then in the system preferences / audio, I wanted to select the alsa output as mentioned. However I only found 'none', 'hdmi', 'analog' and 'analog-hdml'. What's the issue ?
