If anyone is looking to keep their RGB mod functional and use the CD Audio through the SSDS3 I recommend this audio breakout cable from @Arithmaldor on twitter.
It properly grabs the audio from the SSDS3 and the video from the console. Very professionally made with multi-core cabling and true stereo wired MD2 audio.
I got mine yesterday and it works great. It doesn't eliminate the audio buzz issue, but anyone who isn't happy about the video output on the SSDS3 now can bypass it easily.
