To test, connect an amplifier to the RCA out jack on the Hifi-Shield2, and then run:
Applications → Sound & Video → Sound → Hardware Tab & Output Tab select “ODROID-DAC2”
If you want to use the Optical output select “ODROID-HDMI”.
You want to add the Hifi-Shield2 sound_card on ODROID-C2 at boot by editing /etc/rc.local.

odroid@odroid64:~$ sudo nano / etc / rc.local
