I have bought the DAC2 HD, the DSP add-on, and the recording mic. Currently the two boards are attached to my Raspberry Pi 3B, and a light on the DSP is shining green. I used the HiFiBerryOS interface to record and save room compensation measurement for my living room.
But I don't understand how to use this measurement. In the HiFiBerryOS interface, if I click on Sound and then DSP it gives me:
Which seems to imply that it doesn't recognize that a DSP is already attached.
If I go to Room Compensation, I get:
This shows that I have a measurement, but doesn't seem to give me a way to use it either.
Here are a few pictures of the assembly:
