My success story:
1. Install official image (0.4beta) on Raspberry without audio card (Rasp with audio didn't boot)
http://sourceforge.net/projects/runeaud ... z/download
2. Configure WiFi (if you need) by console "wifi-menu" (WebGUI didn't work)
3. Install ArchLinux kernel with Cirrus support (linux-raspberrypi-wsp-4.4.14-2-armv7h)

4. Shutdown, install audio card and boot
5. Go to MPD setup (WebGUI) select Wolfson sound card output (Headphone or Lineout)
Voila! I have working RuneAudio on Raspberry Pi2/3 with Cirrus Logic Audio Card and WiFi.
