Can't find Speaker Audio option

[flyingkunai]

Okay so I've read so many threads about trying to find the Speaker Audio option in pro caster and NOTHING has worked for me.

I'm on a Macbook Pro, OS X Version 10.7.3 and I downloaded procaster version 20.2.69 AND the newest one and nothing is still working.

I just want to stream music videos but it's hard to do with no audio. I had it working once before but I recently tried streaming and viewers complained about "freezing screens" and "choppy audio" so I reinstalled everything and nothing works now.

solutions, anyone?
