Bug Fixes: 
  • UM-779: Make DHCP initial transaction ID a random value
  • UM-111: Bug with latency negotiation results in transmitted audio not received
  • UM-771: Subscriptions fail after reboot / network down using static IP
  • UM-819: Improve ConMon reporting when the device becomes PTP grand leader
  • UM-607: Device does not exit DDM lonely reset after 15 minutes
  • UM-162: Device is unable to subscribe to a multicast flow if the flow's label length is more then 28 characters, instead the Ddvice will create a unicast flow
  • UM-188 If a multicast flow is created on an DIOUSB with a label length of more than 19 characters, other device will be unable to subscribe to the multicast flow, instead devices will subscribe via unicast.
  • MIL-4518: When a device is enrolled in a domain with multiple subnets, when devices are disconnected (or lose power) and reconnected, devices may temporarily lose clock synchronisation before regaining synchronisation
  • UM-682: Device enters fail-safe when connected to a charging port
Known Issues: 
  • UM-807: DDM interop: PTP v2-only devices lose clock sync when a 'preferred leader' boundary clock device is re-enrolled in the domain
  • UM-841: Changing sample rate and rebooting the device removes subscriptions. Workaround: manually re-subscribe the required channels.


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.
