I've just bought a Digi+, but I can't get it to work.
I've installed and updated raspbian to the latest firmware and kernel, and upgraded all packages. I've followed the instructions for installing (edited /etc/modules and /etc/modprobe.d/raspi-blacklist.conf). The on-board LED is green. But the Digi+ doesn't show up as as a sound card when I run 'aplay -l', which just gives me
aplay: device_list:252: no soundcards found...
(I've removed the line 'snd-bcm2835' from /etc/modules. With that line left in I can get output from the B+ standard jack).
What can I do to fix this?
