Hey all, just got a nice used Atomos Shogun Flame and tried to set it up to record today. I'm getting image, but no audio when outputting to 4K (3840x2160) over SDI. Audio does come through when changing the SDI output to 1920x1080 however. Is this possibly a cable issue (need a higher rated SDI cable perhaps?) or a settings/firmware update issue? Any help would be much appreciated!

Note: I'm running a mic directly into the FX6 and can confirm it's good on that end. That mic's audio does come through to the Shogun Flame on 1920x1080, but drops out as soon as I select 3840x2160 on the FX6 SDI output settings.
