PGA: No signal setting any gain other than 1
I set up the example PGA and was encouraged to find that my audio signal (~25mv p-p) was passing through cleanly with no noise. I need to set the gain higher before going onto the next step, but found that changing main.c to set any other gain than PGA_1_GAIIN_01 would cause the audio to stop completely. Am I doing something wrong or is PGA unable to handle low amplitiude imput signal?
