Can't change playback engine (no dropdown menu)

[TanakaShofixti]

Hello,

I recently got a new laptop (Lenovo Yoga 730) and am trying to get my copy of Pro Tools 11 working.

On my old iMac, I could go open Pro Tools and go to Setup > Playback Engine, and choose between several options such as Built-in Output or my Scarlett 2i4 interface.

On my laptop, there's only one option: ASIO4ALL v2, and honestly I don't even know what that is. So when Pro Tools is open, I can only hear Pro Tools through my speakers, and not any other programs.

How can I fix this?
