No audio output, only when opened in edit mode..?

So, I built this M4L device. It works great in Max MSP standalone but doesn't output audio when running inside Ableton Live.

*It does output audio to live when I open it in edit mode. Never happened to me, so weird.

List of things I tried to solve it:

1. [plugin~] and [plugout~] has channels arguments ([plugin~ 1 2])

2. Project Inspector>"Include Packages When Freezing" is ON

3. Project Inspector>"Max For Live Device Type">"Audio"

4. Made sure all .gendsp files are included in the project folder.
