I ohm tested the GPIO cable looks good It follows the picture on the irlp website. I have pin 11 on gm300 attached to pin 8 on irlp cable i also ohm tested the cable as well from radio to board. I have played with the mixer moved the sliders all the way up tested no audio as well as in the middle no audio. It does work correctly on audio out I can turn it up and down and it changes the transmit audio.

What DTMF codes are you seeing when you press the buttons? A table like this would help:

Possible that you have a broken wire on the GPIO.
Your audio problem is likely mixer related. alsamixer is the program you use to set the levels. I assume you are using a USB based sound card, so the sliders shown should be pretty obvious.

I acquired that as well with the irlp board could that also cause no audio?

Did you also acquire or make up the custom ribbon cable between the Pi GPIO port and the board? Usually incorrect digits are due to wiring errors on that cable.

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.
