  • HD-2823: Many improvements were made to improve the device’s resilience to network traffic bursts that it must process. This includes but is not limited to PTP and audio packets.
  • HD-2709: The device doesn’t fallback to link local when the DHCP server is down and the DHCP lease expires.
  • HD-2846: The codec reset GPIO is asserted and deasserted when the device changes the audio clocks. Without a reset, there could be situations which can result in audio artefacts.
  • HD-2837: The device was answering an mDNS query despite the device being in the known answers list.
  • HD-2703: Audio glitches may occur on multicast flows configured with the minimum number of channel slots (e.g., 2 channels per flow); using the maximum slot count (e.g., 4 channels per flow) is not affected.
  • HD-1937: Audio will not recover when the device is enrolled in a SMPTE Dante Domain, DDM is offline and device is rebooted. Workaround: Use a default Dante domain.
  • HD-2115: If a multicast flow with a maximum-character flow name is created on an enrolled device with a maximum-character device name and also maximum-character TX and RX channel names, the multicast flow will not persist across a device reboot. Workaround: Use less characters for the multicast flows OR the device name and channel names.
  • HD-2121: Devices on network may lose sync if a device with “preferred leader” flag enabled joins the network.

Audinate’s Support for Inclusive Language

To our customers: some of the terminology used in Dante products has been changed to align with modern usage. Specifically, areas related to Dante clocking now refer to “Primary Leader Clock”, “Leader Clocks” and “Follower Clocks” to describe the functions of each role more clearly.
