Most switches can pass Dante network audio, but often the default settings can cause issues with your Dante audio network. Here are a few common settings to check if you are having Dante network audio issues:
1. Make sure EEE (Energy-Efficient Ethernet) is disabled, if present.
2. Disallow filtering of unknown multicast traffic as this will block PTP messages.
3. Turn off IGMP snooping.
4. Ensure QoS is properly set up, if available. See guide below for detailed information.
