HiFiBerry Amp 2 settings please


Can someone please give me the correct settings for the current version 2.368 of Volumio and the HiFiBerry Amp 2 board on a Pi 3? I’ve tried a bunch of things, and at times I’ve heard sound, so I know that the hardware is doing something. I’ve had it working pretty well, and then not. I’ve had it only working at full volume, and I’ve had lots of times with either no volume, or an error stating “Failed to open “alsa” [alsa]; Failed to open ASLA device “hw:1,0”: No such file or directory”.
