Quoted from BigSilverPin:Thanks! Reseating every cable and playing with the prongs on each seemed to have fixed it, for now. I also didn't realize how many places/plugs are on the motherboard that can come loose. That seems to be the theme with issues on this game so far, "loose." Loose screws, cables, etc.
I was also confused by that "video" cable. As for the poor sound that gogojohnnyquack referenced, mine was solved instantly with the installation of a ground loop isolator. Now I am back to dialing in my powered sub/game audio, trying to get the levels correct. Would like to hear more about the RCA distinctions pinwoofer , I am not ready to change out the cables but it definitely seems like I'll need a better solution down the line.
Thanks all!
For what it's worth, I've been having intermittent issues with the Right channel cutting out after a few minutes of play. I narrowed it down to the line level cable between the motherboard and amplifier. I replaced it and the issue has gone away. The old cable might have had too much tension on it with one of the zip ties causing strain on the motherboard connection, at least that's my best guess. Or it's just a junky cable. The aux line level is the same type of cable so if you are using that for an external sub or something it might be safer to replace that one too.
