- ETS-5764: Audio sometimes doesn’t start after a reboot
- HD-2427: I2C bus speed slightly faster than 400kHz
- 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.
