Pro Tools Aggregate I/O

[raypiasecki]

Hello, I am having a very disappointing issue, any help would be GREATLY appreciated.

My setup:
Pro Tools | First
Pro Tools 2021.3.1 Trial
Apple MacBook Pro M1
16GB Unified Memory
SSL 2 USB Interface

When I go into Pro Tools | First, my SSL 2 Inputs and Outputs are available to my tracks.

When I am in Pro Tools 2021.2.1 all it recognizes are my built in microphone and speakers. However, when I change the Playback Engine in 2021.3.1 to SSL2, it recognizes the SSL 2 Inputs and Outputs, and, the built in microphone and speakers are no longer available as inputs or outputs.

Both Pro Tools | First and 2021.3.1 have the Playback Engine set to Pro Tools Aggregate I/O.

Any Ideas? Thanks community!
