If you have to load the driver every time whenever your ODROID-C2 starts, simply you can
register the driver into /etc/modules
target
odroid@odroid64:~$ su
Password: /* root password is "odroid" */
root @ odroid64: / home / odroid # echo "snd-soc-pcm5102" >> /etc/modules
root @ odroid64: / home / odroid # echo "snd-soc-odroid-dac" >> /etc/modules
root @ odroid64: / home / odroid # exit
exit
odroid@odroid64:~$
This adds one line at end of the file, /etc/modules, and load the driver on boot automatically.
Create /etc/asound.conf with the following content:
pcm.!default {
type hw card 1
}
ctl.!default {
type hw card 1
}
Reboot again.
Check, if the sound card is enabled with “aplay -l”:
target
odroid@odroid64:~$ aplay -l
