I purchased a modified irlp board for a Raspberry pi3. I have it set up except I am having trouble when I perform readinput the dtmf tones are incorrect. When i run audio_level_test it responds with 0 clipped 0 percent fail. I tried adjusting the alsamixer no change. The audiotest command does work correctly keys radio and is adjustable with alsamixer. I am using a motorola radio gm300 . I have tried another radio and confirmed i have audio out squelched and de-emphasized.
