I got the same problem but somehow I find a way to solve it without using my interface(Focusrite 2i2). To use Equaziler APO and pro tools together you need to send the pro tools audio out to banana voicemeter. so it will look like this:

pro tool audio - banana voicemeter - EQ APO - speaker.

I still can not use EQ APO with my interface yet together with PT . Hope this will help you and give you some idea.
