I didn't get another capture card since it's almost impossible to perfectly sync up audio with the PS4 due to the audio going through the audio port of the DS4.
My issue was that audio would play back in my ears one second after I said it during recording and it fucked with my speech, but if I turned the audio playback down, I would no longer hear the game, so regardless, it was a lose-lose situation. The Elgato people got me to purchase $30 worth of cords to link up between my headset, DS4 and the Elgato itself, only for the audio quality to be cut completely and severely faded out. After all of that, they admitted that there is nothing that can be done due to how the PS4 audio output is structured.
Plus, don't even get me started on fixing audio sync with livestreaming. That was hell on Earth and I never fully fixed it. It was just waaaaay too many problems for the money I paid for it at launch.
