RPi B+ // DAC+ // Volume hardware control


I just received my DAC+ and installed it on a new RPi B+ that has been running Volumio for a week (from the RPi's jack).

Everything seems to work after:

  • Enabling the I2S driver (set to Hifiberry +)
  • Audio output to  sndrpihifiberry
  • Mixer type to software

As soon as I try to switch to Audio Output = ALSA / Mixer Type = Hardware, the music stops (as I guess the RCA isn't even used then ?). As this is a newly installed volumio and a new DAC+ (not the light) this should work if I understand correctly.

The /etc/mpd.conf has the config below in it:

audio_output {

type "alsa"
name "Output"
device "hw:1,0"
mixer_control "Playback Digital"
mixer_device "hw:1"
mixer_index "0"
dop "no"
