Hifiberry DAC - no sound from RCA output

Hi Daniel,

I've got both the DAC+ as well as the Digi+. I've followed the instructions on the Volumio website and i've mounted the images on the SD cards, so now both Pi's have the same OS. My Digi+ outputs via Toslink to my external DAC and that works fine (thank you!) but i am having trouble getting output via my Hifiberry DAC+. I have the USB drive plugged in, FLAC files loaded up, playlist cued up and playing. However, there's no audio signal coming out of the RCA outputs (i've tried different RCA cables - all going into my headphone amplifier). I noticed that under Menu>Playback>Audio Output - i've only the option of "ALSA" whereas on my Digi+ there was something like "sndrpihifiberry" which worked. I'm sorry i don't know what either means but how do i configure it to work?

Thank you for your time.

  Hey Daniel!
  
  I got it to work! I fiddled with the I2S drivers - i selected the Hifiberry + one, and now i'm enjoying the sweet music! YAY!

  Matthew, Daniel;

  Having similar issue with a DAC+ Pro and Pi3 but I'm running Plex Media Player.

  I've retraced my steps from download to flash to dtoverplay but still no output from the two (left & right) RCA connections.

  If I connect an HDMI LED/Speaker kit, I get audio from the monitor's speaker.  Can never get audio from the RCAs,

  Do I need to fiddle "with the I2S drivers" in some way?  Don't know what you meant by that.

  Thanks for your help....

  Hi David,

  what's the output of "aplay -l"? In addition to the configuration of the driver itself, you might also have to select it within Plex. 

  Best regards,
  Daniel

  Hello Sir,

  I got it fudge-working by commenting out the line:

  dtparam=audio=on

  i.e.,

  # dtparam=audio=on

  I have copied below the output of aplay-l before AND after I made the change;

  BEFORE (no output from HiFiBerry DAC+ Pro)

  I would love to have both outputs available as required by usage, hence the fudge-working moniker.
