Question / Help Blackmagic Intensity (PCIe) Audio desync in 2 computer setup

Ok So I recently switched from a 1 PC setup to a PC and Mac Setup. My mac is a 12 core Mac Pro. I have the HDMI out of my PC going into the blackmagic intensity with the audio being sent over the HDMI using Virtual Audio Cable. Virtual Audio Cable is being used at 48k and a 50ms buffer. I have compensated for that using the OBS offset. At the beginning of the stream everything is in sync. By hour 2, the audio is about a second out of sync. OBS is set to 48k, the black magic source has buffering enabled. I have already tried turning off the buffering option, it still desync's. Is this an OBS issue or a Virtual Audio Cable issue? Or is this a known problem?

Here is my log file

Any help will be greatly appreciated.
