Hi, I am on Catalina 10.15.7 and pro tools ultimate 2021.7. The Dolby audio Bridge does not seem to be communicating right with the renderer. Can anyone help
Mac Pro 2019
Avid MTRX Studio
Catalina 10.15.7
Pro tools Ultimate 2021.7
Renderer 3.5

The renderer seems to only get feedback loops when we press play on pro tools.
Everything is installed correct,Peripherals are enabled, i/o is correct and mapped, renderer has been given access to the microphone.
I am lost at this point. Everything works fine on our trash can with the same layout.
Please help.

    Hi there.

    I suggest upgrading to Renderer v3.7 first before troubleshooting. Generally if you are experiencing feedback please ensure that the Dolby Audio Bridge isn't set to the Renderer output device.

    Best,

      LTC issue in Pro Tools. I have upgraded to 3.7 and LTC is no longer syncing off an audio track in Pro tools 2021.7 on Big Sur. All was well on the previous version of Dolby Atmos Renderer on Catalina. Is there a known issue with LTC AAX Plug? I'm confident in my routing using HD Native as that hasn't changed in setup. I have done a clean setup just to be sure.

    There is a new and improved version of the LTC Generator plug-in that was installed with 3.7 and replaced the previous version. If you areopening sessions that used the previous version of the LTC Generator you will need to insert the new version off the LTC Generator plug-in on the same track.
