I sorta fixed that issue .. I edited the decrypt.py and changed the audio instruction in ffmpeg to "libvo_aacenc" instead of "copy"
These are the EDITED lines below

Line 96: subprocess.Popen([ffmpeg, '-i', video_temp_name, '-i', audio_temp_name, '-acodec', 'libvo_aacenc', '-vcodec', 'copy', muxed_temp_name], stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()

Line 111: subprocess.Popen([ffmpeg, '-i', output_temp_name, '-acodec', 'libvo_aacenc', '-vcodec', 'copy', '-bsf:a', 'aac_adtstoasc', out_file],

Now I can hear audio and it plays through out fine .. cept for you can tell a little tiny drop or something in the audio

I'm not sure at all but I think while it's decrypting in the temp folder it pieces the audio back together as full .. I believe they are in chunks so that's why it sounds like that when you play the output.mp4

As its decrypting in the temp folder I was watching it and aac files were being produced over and over I assume it was decrypting pieces by pieces then joined them all into 1 AAC then muxed with FFMPEG ..
