Why are my Metasounds not playing audio?

I just recently started using metasounds but unfortunately I can’t get any of my node setups to output any audio. When I try to play the metasound source the audio channel doesn’t output anything. I thought something might be wrong with the nodes but I checked and nothing seems to be out of place, just no audio.

Update: I got a simple sine wave generator to output sound, so I’ll have to check again and see what’s missing that’s preventing sound output from my other graphs.
