I build a Picade 8" with a Pi 4 inside. Everything went quite smoothly but after installing a raspbian with NOOBs and the picadehat install script, it still doesn’t detect any audio device.
I did install a raspbian since I don’t know if retropi works correctly on Pi4, the download section seems to have only 1 and 2/3 versions…
There is a small red x on the volume control, and when opening sound parameters, I get the following error message:
no ALSA audio device detected
Any idea how to make it work ?
