I just powered up my Zynthian setup again (Raspberry Pi 4B with a 3.5-inch TFT screen). I’m trying to get my Focusrite Scarlett 4i4 3rd Gen to work with it. But no matter what I try—even with the help of ChatGPT—I just can’t get it to work. There is absolutely no sound, even though the system does recognize the soundcard when I run `aplay -l`. Interestingly, MIDI works perfectly fine through the Scarlett 4i4, but I’m getting zero audio output.

Hi @Robroy1974,

I assume that you already tried to select Generic USB Audio as the Zynthian driver in Webconf \> Hardware \> Audio.

Even if it’s not specific for your Scarlett model, it should give you fail-safe audio operation on USB.

Cheers
