Hi @cryoshad,
Just downloaded your image from dropbox. No luck 
Your question is not stupid: I was trying it without any soundcard. I just wanted to see how the touch interface worked, obviously I didn’t expect any sound at all. Now, I must assume the code @jofemodo did check for a working soundcard.
Conclusion, I have to move my Hifiberry from my main Zynthian Box to the new “testing device”.
Thanks a lot for your advices.
Regards, Jose
