How to send channels to group channel

Ok, so I’ve done this before…in fact I have it open and working perfectly in another project, but for some unknown reason I can’t get it to work right again. Hopefully someone can figure out what I missed.

I have a simple mono audio track, and a synth instrument track that I both want to send to a group channel to add an effect. It looks like sending both of these to the group isn’t working for some reason, because when I play audio through the audio channel I dont see the volume monitor on the group track moving at all. Same goes for the synth instrument. I play it, and even though it’s set to the group channel, the volume monitor remains unmoved. Any idea on why this isn’t working? Both ARE indeed sent to that group.

Try creating another group track and re-assigning your channels to it instead and see what happens.
