Dolby Atmos Production Suite (DAPS) bus/bed automation sync issues

[jamesa5454]

Hey all,

I found a cracker this week - tracks that are assigned to a bus AND a Dolby Object appear to have a problem with the synchronization of automation. Look closely at the attached screen shot.

The first 3 tracks contain the exact same clips & volume automation (with a recurring 10dB drop in volume automation displayed on screen) - however the panning position and bus/object assignments are different.

The first track (FX D 1) is panned hard left and is a dual bus/object track; assigned to the bus.

The second track (FX D 2) is panned centre and is dual bus/object track; assigned to an object

The third track (FX D 11) is panned hard right and is ONLY assigned to a bus

The following 3 tracks (FX D 19, 20 & 21) are a recording from the Dolby Atmos Production Suite, that has been imported back into the session. You can clearly see that the timing of the volume automation is a long way out of sync, even though the audio itself is in sync - it is 6 frames early (24fps).

I've only just noticed this problem recently - but I'm pretty sure it didn't exist in the previous release of Pro Tools (2019.10). I'd also guess that the problem is with Pro Tools, as it exhibits itself before audio reaches the renderer.

Setup details as follows:

2019.12 Ultimate (Native)
Dolby Atmos Production Suite 3.4
Dolby Audio Bridge from PT to DAPS
Non Avid (Metric Halo 2882) audio interface from DAPS to monitoring
MacOS 10.13.6
iMac 17,1 (late 2015), 4.2GHz i7, 40GB RAM

Anybody having similar issues?
