MattL (Customer) asked a question.

Album Assembler connects to Renderer (green light), but will not play. Error: External Sync Error.
I've tried with LTC Channel 129 on both, as well as various other channels. The Album Assembler shows in the Renderer's Remote Clients page as a connected remote controller client on 127.0.0.1, but the remote IPs are listed as 192.168.0.177 and ...189.

    Hi,

    Sorry you are running into issues. Can you provide some more information on your system (OS version, Renderer/Assembler versions, audio hardware) as well as the Renderer log files (Help > Open logs folder)?

    The remote IP addresses are used when connecting the Renderer Remote application to control the Renderer.

    -B

        A couple of things:

        -The Renderer and Album Assembler are not qualified with Sonoma. This may be a root cause of the issue, but there are many users who have been able to get it to work.
        -Have you used the Renderer successfully on this system before? If not, this may be an issue with the Dolby Audio Bridge and/or microphone permissions for the Renderer.
