PiFi Digi+ and RPi 3 B+ no audio

Help and Support Help

Hello there!

I’m a little bit stuck here.

My setup is a 3 weeks old Rpi 3 B+ (with a 2.5A PSU) and a “Cambridge Audio DacMAgic+” DAC.
The Songs are stored on my Synology NAS and the Pi is connected via Ethernet to my LAN.
While sending the audio data via USB everything worked so far.

A few days ago I received my PfFi Digi+ v.1 board. Since two days now I’m trying to get it work but without any result.

I tried both spdif connectors (RCA and Toslink) without any success.
I have checked the spdif Inputs on my DAC with other audio sources (TV reciever -> optical and CD player -> digi RCA) and they worked so far.

My Volumino settings:

Activated i2S and chose “HifiBerry Digi+ Pro” and rebooted the system.
After hitting play I hear nothing but I assume volumio plays a song. The volume level is automatically set to 100% and cannot be changed.

I’ve tried switching between DSD mode and DSD over PCM and activated Audio resampling but nothing seem to change a thing.

The volumio version that I originally installed was nr. 2.388 from this thread https://volumio.org/forum/new-rasberry-pi3-t9519.html
and was later upgraded to nr. 2.839 by the volumio system settings.

One more thing. The DAC manual says that only 2 Ch. LPCM or Dolby Digital 2.0 will be accepted. DTS or DD5.1 won’t work.

Maybe anyone can help me.
I would really like to use the PiFi board instead of the usb protocol because I always have to restart the Pi when I turned the Dac off and later on again.
This is quite annoying.

Ok! I finally solved the problem by myself.

I had to choose “Hifiberry Digi” (not Hifiberry Digi+ Pro) and after saving the settings I had to reboot the RPi which I haven’t done before.
And then it worked.

Before I made the board work I also added this line to the config.txt
“dtoverlay=lirc-rpi,gpio_in_pin=26”

I don’t know if it is necessary but I read somewhere that the IRC sensor could cause some problems.
I think the overlay command makes only sense if I install the LIRC protocol but I haven’t tried to get it to work yet.

Hi, sorry it’s been a year since I have looked at this and I cannot remember what I did.
