ProtoDAC TDA1387 X8 project

My experience switching from Polarity Inversion to CamillaDSP.

I went to experiment with CamillaDSP today. In Sections 5.2 and 5.3 of the build guide, they both refer to setting Signal Processing via "Menu, Configure, CamillaDSP". What I found is that Signal Processing was not editable in the CamillaDSP config page . Rather, I had to go to "Menu, Configure, Audio, Equalizers" and select "V2-ProtoDAC" there, then "Edit" to follow. Note: when I didn't find "V2-ProtoDAC" listed, I followed Tim's tip from #432.

I then saw this info in Audio Information

Code:

Audio Chain: MPD -> Polarity inversion -> hw -> Device
.
.
CamillaDSP: V2-ProtoDAC
Volume type: CamillaDSP (64-bit)

Polarity inversion is still in the chain, which I didn't think was possible since I thought it was mutually exclusive with CamillaDSP. I suspect I was double-inverting polarity with this setup (but not sure).

The solution was to disable Polarity Inversion before enabling CamillaDSP. Hopefully this helps the next person.
