I recently purchased, assembled, and installed Runeaudio Beta on my new RPI3. The RPI 3 was the bundled DAC+ from HIFIBerry. The system boots, connects to WiFi, and Spotify. I have also successfully installed the app for android on my Galaxy S7. The RPI is connected via the RCA jacks to a functioning Sunfire Pre-Amp connected to two Carver Amps. However, when a song is selected to play no audio. The app indicates it is playing (the pause icon is present) and all the information with regards to my playlists, song titles, artists names are there but the elapsed time doesn't move much beyond 15 or 20 seconds. FYI, I am new to the whole RPI world!
