Syncing 5.1 audio to Video (Resolve/ Decklink/SDI to audio)

Hi All,

I have a grading suite set up with a Decklink Studio 4K sending video (from Resolve, generally) via HDMI to an OLED client monitor and audio going out SDI from the Decklink, which gets disembedded by a pair of BM SDI- to-Audio 4k boxes and out to speakers. The only problem with this setup is that the sync is not right between the two. When I'm playing DCPs through EasyDCP I'm able to fix the offset in the software, but I can't seem to find any way to tweak the offset when playing out of Resolve. I tried pulling optical out of the OLED, but it won't pass through non-encoded 5.1. Any advice?

Thanks!

Anyone?

Has anyone solved this yet? Is there a simple offset audio by x frames setting in Resolve (And NOT in the Playout settings - that is only for delivering to deck)

Preferences - System - Video and Audio I/O - Audio Monitoring Delay

Does that help at all?
