With the RPI3, to get the Digi+ working you first have to disable Bluetooth. With piCorePlayer 2.04 you need to edit the config file by adding "dtoverlay=pi3-disable-bt". See the following link "http://forums.slimdevices.com/showthread.php?105018-Announce-piCorePlayer-2-00&p=852454&viewfull=1#post852454" on the SlimDevices forum. If you are not familiar with the vi editor try this for a simple introduction http://www.lagmonster.org/docs/vi.html. Sound quality with the Caiman II is excellent.
