I just received my octo sound board with the RCA breakout.
I plugged it into my Pi4 (note: Pi-4) and walked through the "Easy Automatic Setup"
described here: http://forum.audioinjector.net/viewtopic.php?f=9&t=1222
After rebooting my board, both aplay -l and arecord -l just return the message:
aplay/arecord: device_list:272: no soundcards found...
I wanted to start by just doing some basic ALSA stuff.
Any idea where I went wrong?
