FCPX monitoring cam audio issues
My i/o is running though a BMD UltraStudio Express. I have camera originals that are 4 or 5 channels of audio, ID’ed as mono. Most of these are from an ARRI Alexa. I cannot hear any audio until this is on a timeline because it is mono. If I change the camera setting to surround (the only option with 5 mono channels) I can hear the audio. Or – if I use my Mac’s line out audio instead of the UltraStudio, then I can hear the camera audio (without changing channel configuration). Is there a better solution than either of these options? It works fine in Premiere and Media Composer.

EDIT: If you’re on Sierra, see if this helps:

Thanks. The Midi set-up helped. Basically I set it from Stereo to 2.0 Surround and then back to Stereo and it is now fine. Sheesh.

Glad it worked!
I still think Apple needs to do more work on their video I/O, or work with Blackmagic to get drivers that don’t have these issues and the stickiness and delays. These issues don’t exist with Avid and Premiere – just FCPX.

Yep. It’s a known bug. I think it was introduced with Mavericks OS. FWIW, it seems only to affect files that have the pan mode set to “none” – which, of course, would be any file with mono audio.
I thought it was just with AJA I/O hardware. Sorry to hear it affects BMD as well. But at least it’s an easy fix once you know what to do. But I agree – kinda shoddy coming from Apple.
