And yes, I'm posting this in other forums as well.

So my main question is, how would I go about following through on the advice given in the posts above? I don't understand the 'all you need to do is go to your 'Recording' in Sound - go to the line-in and just listen to the playback' part. That's not what I want, I just want it to record the game audio. When I go into my computer's sound settings in my control panel and turn on 'Listen to this device' (and raise the mic volume), heavily distorted audio blasts through my TV of everything going on in my room - my ceiling fan, my voice, and tons of echoing from the console and TV. OBS definitely recognizes all audio coming from my computer that's being played on the TV. Choose the dazzle option and there you go. Anyway, when I have the RCA female stereo-to-male 3.5mm adapter plugged into my PC, I can't hear any audio coming out of my computer at all anymore - now all audio on my computer plays on my TV (I confirmed this by playing iTunes, it plays the song right on top of the game audio on the TV). Here is your problem when you open up the recording option in Windows movie maker itll give you an option to toggle where you want your audio to come from, one option is the sound system of your computer while the other is the dazzle.
