Dante Issue

[Muhammad Ahmad]

There are several potential issues that could be causing the problem you’re experiencing with the audio objects showing at maximum volume or zero and not being correctly placed on the sound stage. Here are some areas to check and troubleshoot:

1. **Clock Sync Issues**: Since Box 1 is handling clock purposes with Via and the Controller, ensure that all devices are properly synchronized to the same clock source. Any clock drift or sync issues can cause audio artifacts and incorrect positioning.
2. **Routing Configuration**: Verify that the routing of audio channels from DaVinci Resolve to the Dolby Atmos Renderer is correctly configured. Ensure that each object channel in DaVinci Resolve is mapped to the correct input channel on the Renderer.
>3. **Level Calibration**: Check the level calibration of the audio channels. Ensure that the levels are correctly set in DaVinci Resolve and that there are no unexpected gain adjustments happening in the Dante Virtual Soundcard or the Renderer.
4. **Dante Virtual Soundcard Settings**: Verify the Dante Virtual Soundcard settings on both Box 2 and Box 3. Ensure that the sample rate, buffer size, and network settings are correctly configured and match across all devices.
5. **Dolby Atmos Renderer Configuration**: Check the configuration settings in the Dolby Atmos Renderer. Ensure that the Renderer is set up to receive the correct number of channels and that the input mappings correspond to the output mappings from DaVinci Resolve.
6. **Metadata Transmission**: Ensure that the positional metadata for each object is being correctly transmitted from DaVinci Resolve to the Dolby Atmos Renderer. Any issues with metadata transmission can result in incorrect placement of objects on the sound stage.
7. **Network Latency and Jitter**: Monitor the network for any latency or jitter issues that could affect the transmission of audio and metadata. Dante Controller software can help in diagnosing network-related problems.
8. **Software Versions and Compatibility**: Ensure that you are using compatible versions of DaVinci Resolve, Dolby Atmos Renderer, and Dante Virtual Soundcard. Any incompatibilities between versions could result in unexpected behavior.
9. **System Resources**: Check the resource usage on each PC (CPU, RAM, network bandwidth) to ensure that none of the systems are being overloaded, which could cause performance issues.

By systematically checking these areas, you should be able to identify and resolve the issue with the audio objects not displaying correctly in the Dolby Atmos Renderer.

This answer reads like ChatGPT which sometimes raises more issues than it answers. The solution was that the sample rate has to be set to 32 bit in Dante. ChatGPT mentions sample rates but Dolby’s response to my query told me what constituted the correct one.
