N/A (bugfix release)

  • ETS-6264: Network timing issues could cause the device’s audio latency to suddenly jump to a higher value and remain stuck until the device was restarted. This was leading to persistent audio delay and degraded performance.
  • HD-1501: When the device is downgraded to the previous GA, it loses part of its persistent storage including DDM credentials and DDM IP and port info. Workaround: Re-apply configuration settings that were lost after the downgrade.
  • UM-807: Dante Domain Manager interop: PTP v2-only devices lose clock sync when a ‘preferred leader’ boundary clock device is re-enrolled in the domain.
  • TRID-520: Dante Domain Manager interop: Device resets when changing latency in domain mode with multicast flows.
  • HD-1843: When the devices are enrolled in a DDM/Dante Director, in different subnets, with unicast clocking enabled, and with unicast audio flows, if the DDM/Dante Director goes offline and devices are rebooted then audio will not recover. Occurs when the AVIO is the only device in a subnet / VLAN with Unicast Clocking enabled. Workaround: Ensure there is at least one other device in each subnet / VLAN with Unicast clocking enabled.
  • HD-1845: When the devices are enrolled in a DDM/Dante Director, in the same subnet, and with multicast audio flows, if the DDM/Dante Director goes offline and devices are rebooted then audio will not recover.
  • HD-1852: When the devices are enrolled in a DDM/Dante Director, in different subnets, with unicast clocking enabled, and with multicast audio flows, if the DDM/Dante Director goes offline and devices are rebooted then audio will not recover.

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.
