The audio and video are always in sync but may be offset due to vision latency.
I do a very similar thing to what you want and include audio into channels 3+4.
I feed the output of my audio desk into a digital delay unit and then into a audio to SDI converter.
I then set the delay accordingly (usually 40mS).
cam audio -> fiber -> audio -> mixer main -> audio delay-> aud to sdi 1 + 2
_________________________mixer m/e -> audio delay-> aud to sdi 3 + 4
