My Raspberry PI 2 works with Volumio and with audio output on HDMI.
Recently I bought this DAC http://www.audiophonics.fr/fr/kits-modules-diy-dac/dac-pcm5102-i2s-p5-32bit384khz-raspberry-pi-p-9637.html apparently born for raspberry PI 2 and declared operating with Volumio, but it doesn’t work.
Audio still remain only on HDMI …
Does anybody knows if there’s any known issues with this DAC or if I have to made any configuration?
Thanks a lot
You can only use one output at the same time, so check with ‘aplay -l’ (run as root) that the DAC is recognized and use the UI to switch the output to use the device instead of the HDMI output.
As first thanks for your kind reply.
Volumio returns:

As you have understood I’m not practical on linux, but I seem to understand that Volumio can see only the HDMI DAC?
Or the external DAC is device #0 end internal HDMI DAC is devide #1?
Your output only shows the default audio of the Pi (analog audio jack and HDMI) and not your new DAC. My guess is that something is not connected properly or not detected. As long as it doesn’t show in this list, it won’t be available to Volumio to use it.
May be the problem is due to a not complete or correct volumio loading.
The UI isn’t completely operating.
Browse, Playback and Playlist works because I can select the music, play, stop and adjust the volume, but the menu isn’t complete and when I try to save the modifies, my browser doesn’t get any reply.
I also can’t turn it off …
This is what appear at the end of Volumio loading.
once more thanks Patrick
EUREKA !!!
After made a new SD and accessed with a PC as client, now I have the access to volumio settings.
Once choose hifiberry+ as DAC, now everything works.
So this good (32bit/384kHz) and cheap (about 35€) DAC probably will be a good choice.
Once more thanks for the advises
Great 
Have fun with it.
Could you post the output of ‘cat /proc/asound’ ( run as root), I am interested to see how this card is recognized.
Glad that your issue is resolved.
Please be patient, the command ‘cat /proc/asound’ doesn’t give me a reply.
aplay -l gives me this:
