"The DAC+DSP profile won't work on the DSP addö-on. Boot HiFiBerryOS and install the latest DSP profile via the GUI."
This news comes rather late for some of us.
Can you please add some .xml examples that work for the DSP add-on. Something to give the functions of the dacdsp-default.xml
What "functions" specifically are you looking for. The DSP profiles come with HiFIBerryOS, but you can also download these from Github:

Many thanks for the information. Those dsp-addon profiles are what I was looking for.
It is quite difficult to find these things. I was looking in the sample xml files under dsptoolkit.
