DCP Audio Stutters on playback in theater

Hi all,

Testing the DCP creation output on Resolve 15 Beta 1, and encountered this showstopping (literally) error.
All DCP's created in Resolve 15, playback fine on the host machine, but when we bring them into our Dolby DCP Server (DSS220) and play them back in the theater, the audio breaks up and stutters. The picture is fine.

DCP specs: 25fps, Kakadu Jpeg2000 2K DCI codec (both flat and scope). Max bitrate set to 200Mbit/sec. Audio Tab set to Linear PCM, Output Track 1 is set to Main 1. I've tried stereo and 5.1 audio as well, both stutter on playback.

The same material is encoded using DCP-o-Matic, same specs and plays back on our projector fine.

This error occurs on both the PC and Mac Versions of of Resolve 15 beta 1.

Mac Specs: iMac Pro (10 core, Vega 64 version, Blackmagic Ultra Studio 4K extreme)

PC Workstation (Built using the Asus x99 Deluxe motherboard recommendations from previous resolve version. 18 core Xeon CPU, x2 Nvidia 1080ti, Decklink 4K Extreme card.)

Thanks!

John

I'm wondering if the 25fps might be 'confusing' the renderer?

I'm going to venture a bet the audio sample rate in the DCP isn't 48kHz
