I have Hifiberry OS running on a Raspberry PI 4, a hifiberry Amp4, and a DSP add-on card.
There is no sound output. I think this might be because there is no DSP program installed. I thought Hifiberry OS comes with this pre-installed. Here is a screenshot:
Unchecking the option "Mute Unknown Programs" does not help. In any case I do want the DSP program installed. Maybe there is a permissions problem in my system?
